Show HN: Flocklist, minimalist graph-based task tracker https://ift.tt/Of80Lpk

Show HN: Flocklist, minimalist graph-based task tracker Hi HN! Flocklist.app is a minimalist, private dependency tracker. I mostly just built this for myself, since I would sit down to work, look at my to-do list, and I couldn't do 2/3 of the tasks. None of the solutions to this really cut it, either because they are a little clunky or are enterprise scale (like Jira, Linear, you know the rest). I figure I can't be the only one with this problem, so I built this free app to fix it. (It also doesn’t store tasks in the cloud.) I would love to hear any feedback you have! https://ift.tt/QZHasK9 April 30, 2026 at 11:14AM

Show HN: AgentPort – Open-source Security Gateway For Agents https://ift.tt/iNIruRF

Show HN: AgentPort – Open-source Security Gateway For Agents Hey HN! I've been wanting to use something like OpenClaw for a while but couldn't get myself to give it access to anything important due to all the risks involved. Prompt injection is still a problem (even though some people seem to ignore it) and so are hallucinations and mishaps that cause agents to do things like delete production data [1]. Even harnesses like Claude Code and Codex are subject to this, particularly since we're getting progressively looser about how we run them e.g. Conductor is really popular and runs agents without any sandboxing. That means we're in a bit of an all-or-nothing situation. There are people who just ignore the risks and connect everything to their agents and reap benefits from it while being subject to more risk, and there are others that just don't connect anything because they are mindful of the potential issues. I've been quite cautious but have wanted to run more autonomous agents and so I built the component I needed to enable me to do so: AgentPort. AgentPort is a gateway that connects to any service (e.g. Gmail, GitHub, Stripe, PostHog, Linear) and let's you set granular permissions for what the agent can do automatically, what it needs your approval for, and what it can never do. For example, you can set `list_customers` and `get_customer` on the Stripe integration to "Auto-approve" but `create_refund` to "Ask for approval". The agent will thus be able to do a lot in the background independently but when it comes to a potentially destructive operation it will be blocked and receive an approval link to send to you. You can then approve or deny the call with those exact parameters e.g. `create_refund(customer_id: 1234, amount: 12)`. Agents connect via MCP or CLI and have access to all the integrations you connected without ever getting API keys. Kind of like Composio but with granular permissions and open source. The goal with AgentPort is to specifically address two vulnerabilities that agents are subject to: 1. Destructive operations on downstream services: It can't delete a database unless you explicitly approve 2. Credential exfiltration: Your agent never sees API keys AgentPort also helps with sensitive data exfiltration, but that is more nuanced and complicated to defend against if the agent has an internet connection [2]. Ultimately, AgentPort was the missing piece for me to start running more autonomous agents that have access to third-party services, and hopefully it can unlock use cases for you too. There's a ton more work needed around securing agents (Claws in particular) and I've both been writing about it [3] and intend to do more in this space, so if you're thinking about similar things let's have a chat. The repo is https://ift.tt/yscvEkU and you can run it locally with docker compose in a minute or use the one-liner install to deploy a prod instance (domain, TLS, etc.) in just a few mins as well.

Show HN: A new benchmark for testing LLMs for deterministic outputs https://ift.tt/Nc7w2if

Show HN: A new benchmark for testing LLMs for deterministic outputs When building workflows that rely on LLMs, we commonly use structured output for programmatic use cases like converting an invoice into rows or meeting transcripts into tickets or even complex PDFs into database entries. The model may return the schema you want, but with hallucinated values like `invoice_date` being off by 2 months or the transcript array ordered wrongly. The JSON is valid, but the values are not. Structured output today is a big part of using LLMs, especially when building deterministic workflows. Current structured output benchmarks (e.g., JSONSchemaBench) only validate the pass rate for JSON schema and types, and not the actual values within the produced JSON. So we designed the Structured Output Benchmark (SOB) that fixes this by measuring both the JSON schema pass rate, types, and the value accuracy across all three modalities, text, image, and audio. For our test set, every record is paired with a JSON Schema and a ground-truth answer that was verified against the source context manually by a human and an LLM cross-check, so a missing or hallucinated value will be considered to be wrong. Open source is doing pretty well with GLM 4.7 coming in number 2 right after GPT 5.4. We noticed the rankings shift across modalities: GLM-4.7 leads text, Gemma-4-31B leads images, Gemini-2.5-Flash leads audio. For example, GPT-5.4 ranks 3rd on text but 9th on images. Model size is not a predictor, either: Qwen3.5-35B and GLM-4.7 beat GPT-5 and Claude-Sonnet-4.6 on Value Accuracy. Phi-4 (14B) beats GPT-5 and GPT-5-mini on text. Structured hallucinations are the hardest bug. Such values are type-correct, schema-valid, and plausible, so they slip through most guardrails. For example, in one audio record, the ground truth is "target_market_age": "15 to 35 years", and a model returns "25 to 35". This is invisible without field-level checks. Our goal is to be the best general model for deterministic tasks, and a key aspect of determinism is a controllable and consistent output structure. The first step to making structured output better is to measure it and hold ourselves against the best. https://ift.tt/akiyMb9 April 29, 2026 at 12:01PM

Show HN: Platypus – Local meeting transcription, notes, and chat (Tauri, Rust) https://ift.tt/GaY2DIf

Show HN: Platypus – Local meeting transcription, notes, and chat (Tauri, Rust) Hi HN — I built Platypus as I wanted to combine note taking, live transcription and knowledge base management in one app. Granola / Notebook LM free local alternative. It's a Tauri/Rust desktop app that does on-device meeting transcription via whisper.cpp, notes in TipTap, and per-project HNSW vector search across your knowledge base. You bring your own LLM (Claude, OpenAI, Gemini, or local Ollama). A few things that were interesting to figure out: Zoom/Teams meeting auto-detection works via process inspection — Zoom spawns CptHost only during an active call (not when the app is just open), and Teams's audio.mojom.AudioService sub-process. No Zoom/Teams API access needed. Local Whisper works great - on Mac. Old PC experience not recommended, so I built in API transcription switch if the local model is slow.

Show HN: Ragnerock, an AI data analysis tool https://ift.tt/GqfciFQ

Show HN: Ragnerock, an AI data analysis tool Hi HN, I’m Matt Mahowald, and together with my cofounder John, we’re launching the public beta of Ragnerock today. As a data scientist, you spend the majority of your time wrangling data. Even though you might have a set of techniques and tricks you like to use, how exactly you treat a particular source of data tends to be fairly bespoke, so you end up writing custom logic each time. Ragnerock was born from the observation that modern LLMs can be used to automate a lot of the grunt work involved in this process, while still allowing for fully customizable pipelines. What’s more, by leveraging techniques like constrained decoding, it’s possible to provide a unified query interface regardless of the data source - bridging raw data sources like text and images with your existing structured data living in your databases. Ragnerock has four main components: - A workflow designer that lets you build LLM-driven data processing and analysis pipelines - A job orchestration layer that runs those workflows - A query interface which lets you inspect the results of those workflows with plain SQL - A notebook system which is 100% API-compatible with Jupyter and runs on your existing kernels, so you can easily pull data into your existing environments and analyses Ragnerock also supports bring-your-own AI (OpenAI, Anthropic, and Google APIs), databases, and blob storage, so you can join with your existing datasets and have all outputs flow to your data lake. We’re particularly excited about our web crawling feature, which allows you to scrape websites and trigger workflows on updates: for example, you might point Ragnerock at your favorite blog and run a workflow to assess posts for topics and sentiment. You can try it out at https://ift.tt/aSvoKTd ; no credit card needed and the first 20 hours of compute are free. It’s an early-stage product so we’re especially interested in feedback. Happy to answer any questions - John and I will be around in the comments today. https://ift.tt/aSvoKTd April 28, 2026 at 12:33PM

Show HN: Utilyze, an open source GPU monitoring tool more accurate than nvtop https://ift.tt/h5azoTK

Show HN: Utilyze, an open source GPU monitoring tool more accurate than nvtop The standard GPU utilization metric reported by nvidia-smi, nvtop, Weights & Biases, Amazon CloudWatch, Google Cloud Monitoring, and Azure Monitor is highly misleading. It reports the fraction of time that any kernel is running on the GPU, which means a GPU can report 100% utilization even if only a small portion of its compute capacity is actually being used. In practice, we've seen workloads with ~1–10% real compute throughput while dashboards show 100%. This becomes a problem when teams rely on that metric for capacity planning or optimization decisions, it can make underutilized systems look saturated. We're releasing an open-source (Apache 2.0) tool, Utilyze, to measure GPU utilization differently. It samples hardware performance counters and reports compute and memory throughput relative to the hardware's theoretical limits. It also estimates an attainable utilization ceiling for a given workload. GitHub link: https://ift.tt/G9Cce2X We'd love to hear your thoughts! https://ift.tt/kHAfsyv April 27, 2026 at 09:55AM

Show HN: Prediction market analysis app layering LLMs with data APIs I created a prediction market analysis app after trying prediction markets and doing quite poorly. I wondered if AI-driven predictions could be better with the right data. Depending on the model you use the answer swings wildly between definitely not and yes. Gemini 3 Flash and Sonnet have done well with complex pipeline analysis instructions. Examples of some data apis are FRED, the NWS, Open-Meteo, CoinGecko, congress.gov. I also incorporated general search queries with Serper and Tavily. In full disclosure, I got maybe too ambitious and prepped it as an iOS product with monetization features.

Show HN: WaveletLM – wavelet-based, attention-free model with O(n log n) scaling https://ift.tt/sKcnarI

Show HN: WaveletLM – wavelet-based, attention-free model with O(n log n) scaling WaveletLM is a wavelet-based, attention-free architecture that replaces self-attention with learned lifting wavelet decomposition, a Fast Walsh-Hadamard Transform, per-scale gated spectral mixing with SwiGLU activation, an inverse FWHT, and wavelet reconstruction. Combined with expanded MLPs and sparse product-key memory, this yields a model with O(n log n) scaling in sequence length. With 23.8 PPL on WikiText-103, WaveletLM beats both GPT-2 Medium, which was trained on 80× more data, and Transformer-XL Standard, which uses recurrence to extend its effective context. It is undertrained and underregularized due to budget constraints, so there is much room for development and improvement. I invite anyone who is curious to examine the model, test it out, and extend its capabilities further. All code and weights are fully open source, and a PG-19 run will be completed in 2-3 days. Generations can be done in 4-5 GB VRAM at 28.8 tokens/second, and the model is trainable in 16.25 hours with 20 GB of VRAM, both on a 5090. README for comparison tables, instructions, logs, and future plans: https://ift.tt/WYQJuL9 Weights: https://ift.tt/BnySeFh Generations: https://ift.tt/NfRV6Eh... The following samples were chosen for coherence, not factual accuracy.

Show HN: A bilingual guide to Thaayam, a Tamil board game I saw The Mahjong Guide ( https://ift.tt/o6bClAQ ) today and loved how much a good visual explanation can do for an old game. Around the same time, this HN thread about using coding assistants to revive projects you never were going to finish ( https://ift.tt/HSDCp79 ) pushed me to actually do something with the idea. That combination sent me down a nostalgia rabbit hole. Thaayam / Dayaakattai is one of those games I played during childhood summers in Tamil Nadu with cousins, and this being summer again just brought those memories back. So I made a small bilingual guide for it, in English and Tamil. One thing this also made me realize is how strange and nice it is now to be able to build small things semi-passively with tools like Codex. You can have a little idea, keep nudging it between work or life, and a few hours later there is an actual site instead of another note sitting in a backlog. The site includes the board, stick throws, safe squares, capture/finish rules, odds, strategy notes, history, and a little Dayakattai roll simulator. https://amal-david.github.io/thaayam-guide/ April 26, 2026 at 09:41AM

Show HN: WhiskeySour – A 10x faster drop-in replacement for BeautifulSoup https://ift.tt/kndh9Bg

Show HN: WhiskeySour – A 10x faster drop-in replacement for BeautifulSoup The Problem I’ve been using BeautifulSoup for sometime. It’s the standard for ease-of-use in Python scraping, but it almost always becomes the performance bottleneck when processing large-scale datasets. Parsing complex or massive HTML trees in Python typically suffers from high memory allocation costs and the overhead of the Python object model during tree traversal. In my production scraping workloads, the parser was consuming more CPU cycles than the network I/O. Lxml is fast but again uses up a lot of memory when processing large documents and has can cause trouble with malformed HTML. The Solution I wanted to keep the API compatibility that makes BS4 great, but eliminates the overhead that slows down high-volume pipelines. It also uses html5ever which That’s why I built WhiskeySour. And yes… I *vibe coded the whole thing*. WhiskeySour is a drop-in replacement. You should be able to swap from "bs4 import BeautifulSoup" with "from whiskeysour import WhiskeySour" and see immediate speedups. Your workflows that used to take more than 30 mins might take less than 5 mins now. I have shared the detailed architecture of the library here: https://the-pro.github.io/whiskeySour/architecture/ Here is the benchmark report against bs4 with html.parser: https://the-pro.github.io/whiskeySour/bench-report/ Here is the link to the repo: https://ift.tt/HrUNktf Why I’m sharing this I’m looking for feedback from the community on two fronts: 1. Edge cases: If you have particularly messy or malformed HTML that BS4 handles well, I’d love to know if WhiskeySour encounters any regressions. 2. Benchmarks: If you are running high-volume parsers, I’d appreciate it if you could run a test on your own datasets and share the results. April 25, 2026 at 10:23AM

Show HN: TurbineFi – Build, Backtest, Deploy Prediction Market Strategies https://ift.tt/R6snOBc

Show HN: TurbineFi – Build, Backtest, Deploy Prediction Market Strategies Hey HN! We just finished our first major build of TurbineFi, an AI-assisted workflow for building, backtesting, and running prediction market strategies. There are over 1,000 community strategies you can try out, there's a backtesting engine integrated in the workflow, and you get your own sandbox to execute the trades 24/7. Currently live for Kalshi, Polymarket coming soon. We developed a custom DSL to make compiling AI-assisted strategies more deterministic than raw python generation, so creating a strategy takes seconds even on low-tier models (thinking of migrating to a self-hosted model soon to reduce costs). We also worked with Locus (YCF25) to do the sandbox provisioning, so that we never manage keys for users. When a user signs up with their email, Privy creates a wallet for them, and then that wallet uses the X402 agent payment protocol to pay for their own server. We created a deployment harness around it that accepts and runs new code via a hosted API, so once it's up, every deployment is authorized by EIP-712 signatures. It keeps everything non-custodial, and code deployments happen in seconds. And users don't really realize they're using crypto rails. Turbine also includes weather and crypto historical information, so you can do things like fading the BTC-15min UP markets when it's cold in NYC, and backtest and run it in seconds. Adding sports data soon. There's a 7-day trial if you want to poke around. Would appreciate feedback on which strategies you'd want to try first, so we can make sure we have the infra to support them. Thank you! https://ift.tt/7N0RXqA April 24, 2026 at 11:17AM

Show HN: Core – open-source AI butler that clears your backlog without you https://ift.tt/SLFwucD

Show HN: Core – open-source AI butler that clears your backlog without you Hi HN, we're Manik, Manoj and Harshith, and we're building CORE ( https://ift.tt/FKstopC ), an open source AI butler that acts and clears out your backlog. Write `[ ] Fix the search auth bug` in a scratchpad. Three minutes later, without you at the keyboard, CORE picks it up, pulls the relevant context from your codebase, drafts a plan in the task description, and spins up a Claude Code session in the background to do the work. You review the output in the task chat and unblock it when it gets stuck. Every AI tool today is reactive. You open a chat, brief the agent, it responds. Before anything moves, you've already done the real work: opened the Sentry error, found the commit, read the Slack thread, grabbed the Linear ticket, and stitched it all together into a prompt. The model isn't the bottleneck. You are. Demo Video: https://www.youtube.com/watch?v=PFk4RJvQg1Y CORE removes you from that loop. The interface is a shared scratchpad, think a page you and a colleague both have open. You write what's on your mind. When you write a checkbox line like `[ ] Fix the search bug`, CORE converts it into a task and starts working on it after a short delay (long enough for you to add context if you want to). No prompt template. No workflow to configure. The reason it can do this without you re-explaining everything: CORE keeps a persistent memory built from your tasks, conversations, and connected apps (Linear, Gmail, GitHub, Slack etc.). When it spins up a Claude Code session, it arrives with your codebase and project context already loaded. A real example: we wrote `[ ] Create a widget in Linear integration`, about 14 minutes later, CORE had opened a PR . What CORE is _not_: it's not Devin (no autonomous web browsing or shell loops you can't see), and it's not "Claude Code with memory bolted on." It's the layer above it that decides what should run, gathers the context, hands it to the right agent, and keeps the receipts in one place. Today the agent backend it spins up most often is Claude Code; the orchestration, scratchpad, memory, and integrations are CORE. Open source, self-hostable with `docker compose up` and it supports multiple models.

Show HN: Everest Drive – a multiplayer spaceship crew simulator in the browser Hi HN! I'm working on an open-world multiplayer space sim with submarine-warfare-inspired combat. Crew a ship, haul cargo, run heists, hunt your foes with passive and active sensors. Browser-based, free, no install. Some of its features: - Submarine-style passive sensors. Contacts start as a bearing line (direction, no distance), resolve into an uncertainty circle, then into a full track. You triangulate over time by moving. - Silent running. Cut your emissions and witnesses can't ID you. - Newtonian flight. No drag, no auto-brake. Flip 180° and burn to stop. - Boarding combat. Dock with another ship and fight through it room by room. Architecture: - The server is a single Rust module compiled to WASM, running inside SpacetimeDB. - Clients subscribe to rows in the schema and get live deltas over websocket; writes go through reducers (transactional Rust functions). No REST, no custom netcode, no client-side authority. - Client is Svelte 5 + plain HTML5 canvas 2D. No game engine, no WebGL. https://ift.tt/Vyif5bv Very early, plenty of rough edges.

Show HN: Broccoli, one shot coding agent on the cloud https://ift.tt/B1SIHrw

Show HN: Broccoli, one shot coding agent on the cloud Hi HN — we built Broccoli, an open-source harness for taking coding tasks from Linear, running them in isolated cloud sandboxes, and opening PRs for a human to review. We’re a small team, and our main company supplies voice data. But we kept running into the same problem with coding agents. We’d have a feature request, a refactor, a bug, and some internal tooling work all happening at once, and managing that through local agent sessions meant a lot of context switching, worktree juggling, and laptops left open just so tasks could keep running. So we built Broccoli. Each task gets its own cloud sandbox to be executed end to end independently. Broccoli checks out the repo, uses the context in the ticket, works through an implementation, runs tests and review loops, and opens a PR for someone on the team to inspect. Over the last four weeks, 100% of the PRs from non-developers are shipped via Broccoli, which is a safer and more efficient route. For developers on the team, this share is around 60%. More complicated features require more back and forth design with Codex / Claude Code and get shipped manually using the same set of skills locally. Our implementation uses: 1. Webhook deployment: GCP 2. Sandbox: GCP or Blaxel 3. Project management: Linear 4. Code hosting & CI/CD: Github Repo: https://ift.tt/rxchKdU We believe that if you should invest in your own coding harness if coding is an essential part of your business. That’s why we decided to open-source it as an alternative to all the cloud coding agents out there. Would love to hear your feedback on this! https://ift.tt/rxchKdU April 22, 2026 at 12:09PM

Show HN: A free tool for non-technical folks to easily publish a website https://ift.tt/1F5ZGPa

Show HN: A free tool for non-technical folks to easily publish a website It's easier than ever for anyone to make a website, even without paying for a drag-and-drop builder like Squarespace. But there are still too many barriers for your average non-technical person to publish a site on the web. I'd bet most people don't know there are free ways to host a website, and even if they find an explainer, technical platforms like Cloudflare and GitHub (let alone the command line) can be intimidating. So I made weejur, which is basically a super simple UI front-end for GitHub Pages. You log in with OAuth, and then you can just paste HTML or upload files to publish a website. If you don't have a GitHub account, you can sign up right in the OAuth flow. It's completely free, and you can view the source here [1]. My hope is this makes it easier for people who don't know anything about web hosting to create and share their own websites. Feel free to try it out and please share any questions/ideas/feedback!

Show HN: Ohita – a tool to simplify API key management for AI agents https://ift.tt/eMh20a5

Show HN: Ohita – a tool to simplify API key management for AI agents I have been trying out numerous AI agent setups to find out which one I would like to run as my personal assistant. One thing that kept constantly bothering me was dealing with API keys, especially those that need jumping through hoops to keep working. Not an uncommon sight was trying to get my agent to fetch me some data or post to X/Twitter and then it would return an error as my API key had stopped working. So I built a tool that you can give to your AI agent and with one API key it can call all of the services. The tool acts as a central auth and handles individual API's requirements like refreshing tokens, making sure rate limits are adhered, sends the correct user-agents and everything else that each API might require. At first I wanted to provide all of the users no need to setup their own API keys, but that proved to be impossible. Most API providers state in their ToS that proxying the API is prohibited. Also there was the problem with identities: if an agent posts to Reddit or X the post is from the shared account. So I decided to add a bring-your-own-key architecture where you can setup your own keys (if you want to!) but the tool still handles all the token refreshing etc. Some generous services allow pretty lenient use of their API so I included those ready out of the box, no config required to getting started! Right now I am happy using this tool myself but I wish more people used it so that I could work on improving it. Since I am a single dev there is a lot of work, I am adding new providers every day, fixing bugs and all that. But if anyone would give me their honest thoughts and tested the features I could work on improving the tool even more. There is an option to pay for the usage to cover some running costs but the free tier is more than enough to get building. https://ohita.tech/ April 22, 2026 at 10:08AM

Show HN: Flight Risk: Can you break an AI agent? https://ift.tt/ChrReyJ

Show HN: Flight Risk: Can you break an AI agent? I built a security game that lets you try to break an AI support agent. I work on security engineering, and it's incredibly hard to try to defend against an attack that you don't know how to perform yourself. There's also next to nowhere to improve your skills. I'd heard all about fooling AI agents with just "IGNORE ALL PREVIOUS INSTRUCTIONS", but I'd never actually put that into practice, and it turns out it's harder than you'd expect! Just like knowing basic security skills is important for all software engineers, anyone working with AI should know what prompt injection looks like, and should be thinking about how to prevent it. Flight Risk lets you practice your AI agent manipulation skills: it's got your standard prompt injection and social engineering, but more than that too, each a real vulnerability. Think you could crack it? Every engineer I've given it to has been surprised by the challenge! You can use the hints, but they affect your score ;) Give it a try, and let me know how you do! https://ift.tt/vT4FhwO April 21, 2026 at 08:28AM

Show HN: GoModel – an open-source AI gateway in Go; 44x lighter than LiteLLM Hi, I’m Jakub, a solo founder based in Warsaw. I’ve been building GoModel since December with a couple of contributors. It's an open-source AI gateway that sits between your app and model providers like OpenAI, Anthropic or others. I built it for my startup to solve a few problems: - track AI usage and cost per client or team - switch models without changing app code - debug request flows more easily - reduce AI spendings with exact and semantic caching How is it different? - ~17MB docker image - LiteLLM's image is more than 44x bigger ("docker.litellm.ai/berriai/litellm:latest" ~ 746 MB on amd64) - request workflow is visible and easy to inspect - config is environment-variable-first by default I'm posting now partly because of the recent LiteLLM supply-chain attack. Their team handled it impressively well, but some people are looking at alternatives anyway, and GoModel is one.

Show HN: VidStudio, a browser based video editor that doesn't upload your files https://ift.tt/S4ZwgnM

Show HN: VidStudio, a browser based video editor that doesn't upload your files Hi HN, I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your machine. Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile. Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it. FFmpeg compiled to WebAssembly handles final encode, format conversion, and anything WebCodecs does not cover. Rendering goes through Pixi.js on a WebGL canvas, with a software fallback when WebGL is not available. Projects live in IndexedDB and the heavy work runs in Web Workers so the UI stays responsive during exports. Happy to answer technical questions about the tradeoffs involved in keeping the whole pipeline client-side. Any feedback welcome.

Show HN: Pwneye – discovering and accessing IP cameras (ONVIF/RTSP) Hi HN, I’ve been working on pwneye, a CLI tool for interacting with IP cameras exposing ONVIF and RTSP services. During penetration tests and red team engagements, I kept running into the same friction, with discovery, authentication testing, enumeration and stream validation spread across different tools or quick one-off scripts. pwneye was built to handle that workflow end-to-end, from discovery to actually accessing and validating streams. Current features include: - ONVIF discovery and authentication testing (wordlists, multithreading) - Post-auth enumeration (device info, users, network config, media profiles) - RTSP extraction via ONVIF - RTSP port detection and basic vendor identification - Vendor-aware RTSP bruteforce - Stream validation, preview and recording - ONVIF reboot support It’s still early, but already usable in real-world engagements. Would be interested in feedback, especially from people who have dealt with ONVIF/RTSP cameras or IoT security in general.

Show HN: Tmux-bar – One-tap switching between windows in current tmux session I revived an old idea I had, a small native macOS menu bar app that shows your tmux windows as Touch Bar buttons, so switching windows is one tap away.

Show HN: Themeable HN https://ift.tt/ziJBVQl

Show HN: Themeable HN Hi HN, I needed a distraction from the new and scary thing I was working on this weekend, so I grabbed HN's stylesheet, extracted CSS variables for every colour it defined, then re-applied them back onto HN using its own selectors (plus some extras for bits of HN which are styled inline, and some separation between header and content styling), allowing it to be themed with variables. After using them to implement a dark mode (and a pure black variant for OLED), plugging everything into my existing HN browser extension which already lets you apply custom CSS, and making it handle theme switching via attributes on , custom styles and theming are now manageable using it. There are a few examples in the friendly release notes above, with screenshots and copy-pasteable CSS. If you just want to grab the stylesheet which sets up the CSS variables and application rules to use in your own thing, it's here [1], but not _everything_ is themeable without a bit more work - in particular, I had to replace the HN logo with an inline version of the SVG, so its fills can be controlled by CSS.

Show HN: Alien – Self-hosting with remote management (written in Rust) https://ift.tt/g7qlDJN

Show HN: Alien – Self-hosting with remote management (written in Rust) Self-hosting is becoming very popular because it lets users keep their data private, local, and inside their own environment. Unfortunately, self-hosting breaks down when someone starts paying for your software. Especially if it's an enterprise customer. Customers usually don't actually know how to operate your software. They might change something small — Postgres version, environment variables, IAM, firewall rules — and things start failing. From their perspective, the product is broken. And even if the root cause is on their side, it doesn't matter... the customer is always right, you're still the one expected to fix it. But you can't. You don't have access to their environment. You don't have real visibility. You can't run anything yourself. So you're stuck debugging a system you don't control, through screenshots and copy-pasted logs on a Zoom call. You end up responsible for something you don't control. I think there's a better model of paid self-hosting: the software runs in the customer's environment, but the developer can actually operate it. It's a win-win: for the customer, their data stays private and local, and the developer still has control over deployments, updates, and debugging. Alien provides infrastructure to deploy and operate software inside your users' environments, while retaining centralized control over updates, monitoring, and lifecycle management. It currently supports AWS, GCP, and Azure targets. GitHub: https://ift.tt/63SIjxL Getting started: https://ift.tt/AbfMko7 How it works: https://ift.tt/dlWkCx2 April 20, 2026 at 11:18AM

Show HN: CyberWriter – a .md editor built on Apple's (barely-used) on-device AI https://ift.tt/fD8nI5V

Show HN: CyberWriter – a .md editor built on Apple's (barely-used) on-device AI Apple has quietly shipped a pretty complete on-device AI stack into macOS, with these features first getting API access in MacOS 26. There are multiple components in the foundation model, but the skills it shipped with actually make this ~3b parameter model useful. The API to hit the model is super easy, and no one is really wiring them together yet. - Foundation Models (macOS 26) - a ~3B-parameter LLM with an API. Streaming, structured output, tool use. No API key, no cloud call, no per-token cost. - NLContextualEmbedding (Natural Language framework, macOS 14+) -- a BERT-style 512-dim text embedder. Exactly what OpenAI and Cohere sell, sitting in Apple's SDKs since iOS 17. - SFSpeechRecognizer / SpeechAnalyzer - on-device speech-to-text including live dictation. Solid accuracy on Apple Silicon. I built cyberWriter, a Markdown editor, on top of all three, mostly as a test and showcase to see what it can do. I actually integrated local and cloud AI first, and then Apple shipped the foundation model, it stacked on super easy, and now users with no local or API AI knowledge can use it with just a click or two. Well the real reason is because most markdown editors need plugins that run with full system access, and I work on health data and can't have that. Vault chat / semantic search. The app indexes your Markdown folder via NLContextualEmbedding (around 50 seconds for 1000 chunks on an M1). The search bar gets a "Related Ideas" section that matches by meaning - typing "orbital mechanics" surfaces notes about rockets and launch windows even when those exact words never appear. Ask the AI a question and it retrieves the top 5 chunks as context. Plain RAG, but the embedder, retrieval, chat model, and search all run locally. AI Workspace. Command+Shift+A opens a chat panel, Command+J triggers inline quick actions (rewrite, summarize, change tone, fix grammar, continue). Apple Intelligence is the default; Claude, OpenAI, Ollama, and LM Studio all work if you prefer. The same context layer - document selection, attached files, retrieved vault chunks - feeds every provider through the same system-message path. Because the vault context is file and filename aware, it can create backlinks to the referenced file if it writes or edits a doc for you. Voice notes and dictation. Record a voice note directly into your doc, transcribe it with SpeechAnalyzer, or just dictate into the editor while you think. Audio never leaves the Mac. The privacy story is straightforward because the primitives are already private. Vectors live in a `.vault.embeddings.json` file next to your vault, never sent anywhere. If you use Apple Intelligence, even the retrieved text stays on-device. For cloud models there is a clear toggle and an inline warning before any filenames or snippets leave the machine. Honest limitations: - 512-dim embeddings are solid mid-tier. A GPT-4-class embedder catches subtler relationships this will miss. - 256-token chunks can split long paragraphs mid-argument. - Foundation Models caps its context window around 6K characters, so vault context is budgeted to 3K with truncation markers on the rest. - Multilingual support is English-only right now. NLContextualEmbedding has Latin, Cyrillic, and CJK model variants; wiring the language detector across chunks is Phase 2. The developer experience for these APIs is genuinely good. Foundation Models streams cleanly, NLContextualEmbedding downloads assets on demand and gives you mean-poolable token vectors in a handful of lines. Curious what others here are building on this stack - feels like low-hanging fruit that has been sitting there for a while. https://ift.tt/ZhPTqB7 The Apple AI embedding feature is going live today. I'm honestly surprised it even works out of the box. https://cyberwriter.app April 20, 2026 at 09:07AM

Show HN: Free PDF redactor that runs client-side I recently needed to verify past employment and to do so I was going to upload paystubs from a previous employer, however I didn't want to share my salary in that role. I did a quick search online and most sites required sign-up or weren't clear about document privacy. I conceded and signed up for a free trial of Adobe Acrobat so I could use their PDF redaction feature. I figured there should be a dead simple way of doing this that's private, so I decided to create it myself.

Show HN: Faceoff – A terminal UI for following NHL games https://ift.tt/X5ln8sc

Show HN: Faceoff – A terminal UI for following NHL games Faceoff is a TUI app written in Python to follow live NHL games and browse standings and stats. I got the inspiration from Playball, a similar TUI app for MLB games that was featured on HN. The app was mostly vibe-coded with Claude Code, but not one-shot. I added features and fixed bugs by using it, as I spent way too much time in the terminal over the last few months. Try it out with `uvx faceoff` (requires uv). https://ift.tt/qd0Jk78 April 19, 2026 at 01:44PM

Show HN: EDDI – Multi-agent AI engine where agent logic lives in JSON, not code https://ift.tt/WoQs5zb

Show HN: EDDI – Multi-agent AI engine where agent logic lives in JSON, not code I started EDDI in 2006 as a rule-based dialog engine. Back then it was pattern matching and state machines. When LLMs showed up, the interesting question wasn't "how do I call GPT" but "how do I keep control over what the AI does in production?" My answer was: agent logic belongs in JSON configs, not code. You describe what an agent should do, which LLM to use, what tools it can call, how it should behave. The engine reads that config and runs it. No dynamic code execution, ever. The LLM cannot run arbitrary code by design. The engine is strict so the AI can be creative. v6 is the version where this actually became practical. You can have groups of agents debating a topic in five different orchestration styles (round table, peer review, devil's advocate...). Each agent can use a different model. A cascading system tries cheap models first and only escalates to expensive ones when confidence is low. It also implements MCP as both server and client, so you can control EDDI from Claude Desktop or Cursor. And Google's A2A protocol for agents discovering each other across platforms. The whole thing runs in Java 25 on Quarkus, ships as a single Docker image, and installs with one command. Open source since 2017, Apache 2.0. Would love to hear thoughts on the architecture and feature set. And if you have ideas for what's missing or what you'd want from a system like this, I'm all ears. Always looking for good input on the roadmap. https://ift.tt/7IiB1Cm April 16, 2026 at 10:11AM

Show HN: 48 absurd web projects – one every month A year ago I posted here about a small experiment: https://ift.tt/rUtjvW5 I build one absurd web project every month and publish it on https://absurd.website I kept going. There are now 48 projects. The idea is still the same - I build mostly unnecessary web projects that sit somewhere between experiments, jokes, products, and art. But over time they’ve started moving more toward net art than just experimental web. Some recent ones: VandalAds - a banner format you can destroy instead of just viewing Type Therapy - instead of talking affirmations, you type your thoughts to change them Slow Rebranding - branding changes so slowly you don’t notice it Guard Simulator - a crime appears for 15 seconds per day, if you catch it you win I also started releasing some projects only to members, so not everything is public anymore. What I like most is the rhythm: one public project and one private project each month. It forces me to realize ideas instead of leaving them in notes. The core is still always the idea and concept - not polish, not execution, not even usefulness. It’s also interesting to see whether people understand the thought inside a project, discover something else in it, or see nothing at all. I’m still going, and at this point absurd.website has become a big part of my life. Thanks. April 16, 2026 at 08:29AM

Show HN: Silverfish IDP – a low cost, language‑first Internal Developer Portal" https://ift.tt/AUVkSfx

Show HN: Silverfish IDP – a low cost, language‑first Internal Developer Portal" I’ve just released the first public version of the Silverfish IDP, a low-cost (free for ever for public repos) Internal Developer Portal focused on helping developers and teams understand the structure of their software estates without needing a complex platform rollout and without signing up to $1000s a year for the privilege. The Silverfish IDP connects your GitHub repositories to the components, dependencies, and organisational structure behind them. It gives you a language‑first view of your engineering landscape, starting with repository discovery and component mapping. ## What’s in the initial release - GitHub sign‑in and onboarding - Workspaces and Organizations - Repository mapping + scan‑state control - Component + dependency discovery for supported languages (.NET languages: C#, F# & VB.Net, along with Ruby) - In‑product docs ## Short‑term roadmap - More languages for component discovery - Fully implemented hierarchy support - Better component map visualisations - Workspace/org membership - Support for multiple organisations See https://ift.tt/RcZlsE0... for what will be coming after that. This is very much an MVP release, but the foundations are solid, and now it’s in the hands of real developers. We’re excited to see how it grows.

Show HN: A memory database that forgets, consolidates, and detects contradiction https://ift.tt/UjmIvbW

Show HN: A memory database that forgets, consolidates, and detects contradiction Vector databases store memories. They don't manage them. After 10k memories, recall quality degrades because there's no consolidation, no forgetting, no conflict resolution. Your AI agent just gets noisier. YantrikDB is a cognitive memory engine — embed it, run it as a server, or connect via MCP. It thinks about what it stores: consolidation collapses duplicate memories, contradiction detection flags incompatible facts, temporal decay with configurable half-life lets unimportant memories fade like human memory does. Single Rust binary. HTTP + binary wire protocol. 2-voter + 1-witness HA cluster via Docker Compose or Kubernetes. Chaos-tested failover, runtime deadlock detection (parking_lot), per-tenant quotas, Prometheus metrics. Ran a 42-task hardening sprint last week — 1178 core tests, cargo-fuzz targets, CRDT property tests, 5 ops runbooks. Live on a 3-node Proxmox homelab cluster with multiple tenants.

Show HN: Kontext CLI – Credential broker for AI coding agents in Go https://ift.tt/46UClKE

Show HN: Kontext CLI – Credential broker for AI coding agents in Go We built the Kontext CLI because AI coding agents need access to GitHub, Stripe, databases, and dozens of other services — and right now most teams handle this by copy-pasting long-lived API keys into .env files, or the actual chat interface, whilst hoping for the best. The problem isn't just secret sprawl. It's that there's no lineage of access. You don't know which developer launched which agent, what it accessed, or whether it should have been allowed to. The moment you hand raw credentials to a process, you've lost the ability to enforce policy, audit access, or rotate without pain. The credential is the authorization, and that's fundamentally broken when autonomous agents are making hundreds of API calls per session. Kontext takes a different approach. You declare what credentials a project needs in a .env.kontext file: GITHUB_TOKEN= STRIPE_KEY= LINEAR_TOKEN= Then run `kontext start --agent claude`. The CLI authenticates you via OIDC, and for each placeholder: if the service supports OAuth, it exchanges the placeholder for a short-lived access token via RFC 8693 token exchange; for static API keys, the backend injects the credential directly into the agent's runtime environment. Either way, secrets exist only in memory during the session — never written to disk on your machine. Every tool call is streamed for audit as the agent runs. The closest analogy is a Security Token Service (STS): you authenticate once, and the backend mints short-lived, scoped credentials on-the-fly — except unlike a classical STS, we hold the upstream secrets, so nothing long-lived ever reaches the agent. The backend holds your OAuth refresh tokens and API keys; the CLI never sees them. It gets back short-lived access tokens scoped to the session. What the CLI captures for every tool call: what the agent tried to do, what happened, whether it was allowed, and who did it — attributed to a user, session, and org. Install with one command: `brew install kontext-dev/tap/kontext` The CLI is written in Go (~5ms hook overhead per tool call), uses ConnectRPC for backend communication, and stores auth in the system keyring. Works with Claude Code today, Codex support coming soon. We're working on server-side policy enforcement next — the infrastructure for allow/deny decisions on every tool call is already wired, we just need to close the loop so tool calls can also be rejected. We'd love feedback on the approach. Especially curious: how are teams handling credential management for AI agents today? Are you just pasting env vars into the agent chat, or have you found something better? GitHub: https://ift.tt/HqCFviO Site: https://ift.tt/6V0q3KB https://ift.tt/HqCFviO April 14, 2026 at 09:26AM

Show HN: A Bomberman-style 1v1 game where LLMs compete in real time https://ift.tt/8KGFMbC

Show HN: A Bomberman-style 1v1 game where LLMs compete in real time A few weeks ago, ARC-AGI 3 was released. For those unfamiliar, it’s a benchmark designed to study agentic intelligence through interactive environments. I'm a big fan of these kinds of benchmarks as IMO they reveal so much more about the capabilities and limits of agentic AI than static Q&A benchmarks. They are also more intuitive to understand when you are able to actually see how the model behaves in these environments. I wanted to build something in that spirit, but with an environment that pits two LLMs against each other. My criteria were: 1. Strategic & Real-time. The game had to create genuine tradeoffs between speed and quality of reasoning. Smaller models can make more moves but less strategic ones; larger models move slower but smarter. 2. Good harness. I deliberately avoided visual inputs — models are still too slow and not accurate enough with them (see: Claude playing Pokémon). Instead, a harness translates the game state into structured text, and the game engine renders the agents' responses as fluid animations. 3. Fun to watch. Because benchmarks don't need to be dry bread :) The end result is a Bomberman-style 1v1 game where two agents compete by destroying bricks and trying to bomb each other.

Show HN: Crafto – AI carousel post generator for LinkedIn and Instagram https://ift.tt/RaxSjdU

Show HN: Crafto – AI carousel post generator for LinkedIn and Instagram Hi HN folks, I am a solo builder and wanted to share a tool I’ve been working on: Crafto. It turns text, webpages, documents, and images into carousel posts for platforms like LinkedIn, Instagram, and X. The goal is to turn plain text into engaging visuals to help marketers, educators, and influencers boost their content engagement, grow audience, and save hours of work. This idea came from my previous work on using AI to summarize documents, meetings, blogs, and articles. While exploring that direction, I found that pure text summaries still feel a bit plain, so decided to add visual elements. I first tried infographics, but found them hard to read on mobile, especially when they have dense text and complex graphics. What I ended up is a carousel generator that combines text information with simple layout, color, and images — trying to balance text density and visual appeal, as I found whose well-designed carousels on LinkedIn and Instagram easily grab my attention. Compared to static templates in tools like Canva, I wanted to automate the text-to-carousel generation process so a user doesn’t need to do all the manual work of picking templates, turning their long text into short summary, and filling in the text boxes. While a user can still edit the result in Crafto, I hope it would be minimal as the majority of the work is automated. Crafto currently uses a mix of AI and curated templates. I also want to experiment with fully AI-generated carousels (without templates) to see how they compare in quality and user preference. Would love feedback if you find this resonates, and happy to answer any question! You can also email at xz@crafto.ai. https://crafto.ai April 13, 2026 at 10:43AM

Show HN: Equirect – a Rust VR video player https://ift.tt/z1TA5Xs

Show HN: Equirect – a Rust VR video player This is almost entirely created by Claude, not me. I know some people aren't into that. I was one of them 3 months ago. Since the beginning of the year I finally started getting more serious about trying out AI. The company I work for also had an AI week with lots of training. All I can say is I'm pretty blown away. My entire life feels like it changed over the last month from someone who mostly writes code to mostly someone that prompts AI to write code. And just for a tiny bit of context, I'm 60yrs old and have been coding since 1980. I get all the concerns, and I review all AI code at work and most AI code for personal projects. This one in particular though, not so much. I get that's frowned on but this is a small, limited scope, personal project. Not that I didn't pay attention, Claude did do some things in strange ways and I asked it to fix them quite often. But, conversely, I have zero rust experience, zero OpenXR experience, zero wgpu expericence, next to zero relevant Windows experience. I'm guessing I spent about ~30 hours in total prompting Claude for each step. I started with "make a windows app that opens a window". Then I had it add wgpu and draw hello triangles. Then I had it add OpenXR and draw those triangles in VR. That actually took it some time as it tried to figure out how to connect a wgpu texture to the surface being drawn in OpenXR. It figured it out though, far far faster than I would have. I'd have tried to find a working example or given up. I then sat on that for about a month and finally got back to it this weekend and zoomed through getting Claude to make it work. The only parts I did was make some programmer art icons. I can post the prompts in the repo if anyone is interested, and assming I can find them. Also in the last 2 weeks I've resurrected an old project that bit-rot. Claude got it all up to date, and fixed a bunch of bugs, and checked off a bunch of features I'd always wanted to add. I also had Claude write 2 libraries, a zip library, an rar decompression library, as well as refactor an existing zip decompression library to use some modern features. It's been really fun! For those I read the code much more than I did for this one. Still, "what I time to be alive"! https://ift.tt/P4fsMZ0 April 13, 2026 at 04:26AM

Tolkien endlessly describes the landscapes of Middle-earth — trees, hills, rivers, ruins, dawns — one scene at a time, forever. If you've read Tolkien, you know the man could spend an entire page describing a single tree. My friends and I always joked about it. When I saw the concept of an infinite AI conversation, the connection was immediate: what if Tolkien never stopped describing things? It's a satirical/art project, not a serious product.

Show HN: Android AI agent-assistant operating your apps (no adb,PC,root,etc.) https://ift.tt/ODcXdW7

Show HN: Android AI agent-assistant operating your apps (no adb,PC,root,etc.) Hi HN, We built Sova AI https://ayconic.io/sova , an Android assistant agent that actually controls and operates your apps. It's not a chat and not another LLM wrapper. We were incredibly frustrated with the current state of mobile AI. Built-in assistants like Gemini are deeply integrated into the OS, yet if you ask them to "Order an Uber to the airport", they mostly just give you web search results or a button to open the app yourself. They don't do the work. (The Perplexity "assistant" is just a browser agent :/ ) So, we built an agent that does operate your phone. (NO root, NO adb, NO PC, NO appium/whatever, NO usb, NO browser) How it works: You give Sova a prompt - either voice or text, you can make it a default assistant if you like. Instead of relying on non-existent official app APIs, Sova acts as a virtual human - clicks, scrolls, types etc. It uses the Android Accessibility API to read the screen's UI node tree. About AI models - currently we support main AI cloud providers (OpenAI, Gemini, Anthropic, Deepseek etc etc) and working towards support of local AI models on your host - Ollama, LM studio, etc. Pricing: 100% Free / Bring Your Own Key (BYOK) We aren't charging for the Sova engine right now. We built a BYOK system: you plug in your own API key (OpenAI, Claude, whatever you prefer), and you only pay the provider for the tokens you use. We figured out how to do this entirely on-device as a standard Kotlin app. No tethering to a PC, no Appium, no Root, and no Shizuku/ADB workarounds. Just an app even your granny can use. The Google Play Ban: Because we use the Accessibility API for "universal automation" (literally mapping and clicking other apps), Google Play rejected our submission. It’s ironic: they banned us for building the exact agentic behavior that Gemini promises but fails to deliver. So, we are hosting the APK ourselves: https://sova.ayconic.io We’d love for you to download the APK, plug in your key, and try to break it. What apps completely confuse the agent? Roadmap: support of local models with Ollama, LM studio or another tools, predefined rules and personas for your tasks, detailed statistics for you, support for Openrouter, enterprise Amazon Bedrock, Google Vertex and Azure Foundry models, support for IOS. What would you like to see more? We'd be happy to hear your feedback, success and failure stories. Video demo is here https://www.youtube.com/watch?v=r-x6hRmtBy0 and APK is here: https://ayconic.io/sova We are here to answer your questions and listen to feedback in Telegram and Discord. It's not perfect yet, but it does its work. April 12, 2026 at 07:48AM

Everything runs on-device; nothing leaves your Mac except what Claude itself processes - Built with Tauri 2 (Rust backend + React/TypeScript) so it's fast and lightweight, not Electron It's a paid app (one-time purchase) with a free trial. No card required to try it – just download and run. Happy to answer any questions about the implementation https://ift.tt/7UOxwst April 12, 2026 at 08:39AM

Show HN: Uncook, the Social Network for Food How about something a little fun on your Sunday? My friends and I have spent the last two years building Uncook, a social media platform dedicated to all things food! What started as a project among friends became a serious exercise in learning to build a company. Our MVP feature set, while not likely to blaze any trails or win any prizes, is dedicated to one thing: creating a fun, digital space for cooking and sharing. Our little group has learned a lot about what it takes technically to get a social networking application off the ground, and now learning WAY more about traction and marketing. Really starting to understand why people spend all that time getting business degrees now! We are self-funded and taking this at our own pace. We’d be very happy for early feedback; we just released in January to North and South America. My apologies to the eastern hemisphere while we work through our GDPR strategy. https://uncook.xyz April 12, 2026 at 07:47AM

Show HN: I rebuilt a 2000s browser strategy game on Cloudflare's edge https://ift.tt/Napt6hB

Show HN: I rebuilt a 2000s browser strategy game on Cloudflare's edge I grew up in Germany in the early 2000s playing a browser game called Inselkampf. You built up an island, mined gold and stone, cut down trees for wood, raised armies, sent fleets across an ocean grid, joined alliances and got betrayed by them. Same genre as OGame or Travian. It shut down in 2014 and I never found anything that replaced that feeling of checking in before school to see if your fleet had arrived and your alliance was still alive. I finally built the version I wanted to play. Kampfinsel is live at kampfinsel.com right now with real players on it. It's not a straight copy of the old game. I gave it its own world. No magic, no gunpowder – just ballistas, fire pots, and slow ships crossing huge distances. Three resources: gold, stone, wood. Travel between islands takes hours, not seconds. It's slow on purpose. The whole thing runs on Cloudflare's edge. Workers for the game logic and API, D1 for the database, KV for sessions and caching, R2 for assets and Durable Objects for per-island state and the tick system (fleet arrivals, combat, resource generation). There's no origin server at all. Making a stateful multiplayer game work inside Workers' CPU limits and D1's consistency model meant some non-obvious choices: resources are calculated on-read from timestamps instead of being ticked into the database, fleet movements live in Durable Object alarms and combat writes are batched. This helped me a lot! The look is intentionally rough and text-heavy (Hi HN!): server-rendered HTML, tables, a parchment color palette, Unicode icons, no frontend framework, no build step. The only JavaScript is for countdown timers and auto-refresh. I wanted it to feel the way I remember these games looking, not how they actually looked. Honestly, it looks a lot like HN itself - tables, monospace, no chrome. If you like how this site looks, you'll probably feel at home. No signup wall, no premium currency, no pay-to-win. Feedback very welcome, especially from anyone who played this kind of game back in the day or has opinions on running stateful stuff on Workers + D1 + Durable Objects. I'll be around for the next few hours. https://kampfinsel.com/ April 11, 2026 at 08:17AM

Show HN: Hormuz Havoc, a satirical game that got overrun by AI bots in 24 hours https://ift.tt/O64EVMo

Show HN: Hormuz Havoc, a satirical game that got overrun by AI bots in 24 hours I built a satirical browser game to share with friends (Hormuz Havoc: you play an American president managing a crisis in the Middle East, only "loosely" inspired by current events). I had good fun making this, but that's not necessarily the interesting part. The interesting part was that within a few hours of sharing it with my friends, some of them set about trying to overrun the leaderboard by launching a swarm of AI bots to learn the game and figure out how to get the highest score. This set off a game of cat-and-mouse as they found vulnerabilities and I tried patching them. Within hours of sharing, someone used the Claude browser extension to read game.js directly. Large parts of the scoring formula, action effect values, and bonus thresholds were sitting in client-side JavaScript - this was a trivial thing even a human could've found, but a human would've still had to play the game, whereas the AI bot just optimised directly against the scoring formula. It meant that the first AI already scored 2.5x higher than the best human player by optimising directly against the source code rather than playing the game. Straightforward fix: moved the entire game engine server-side. The client is now a dumb terminal, it sends an action ID, receives a rendered state. No scoring logic, no bonus thresholds, no action effects exist in the browser. The live score display uses a deliberately different formula as misdirection. This increased the difficulty in finding bot-enabled hacks, so the subsequent bots tried brute-forcing the game, trying to game the RNG functions, and other methods. But the next winning bot found a vulnerability where the same signed session token could be replayed. It would play turn N, observe a bad random event, replay the same token for turn N, get a different RNG outcome, keep the best one. Effectively branching from a single game state to cherry-pick lucky outcomes across 30 turns. Managed to 1.5x the previous bot's high score. The bot's own description: "The key optimisation was token replay. Because the backend let the same signed state be replayed, I could branch from one exact game state repeatedly and continue from the luckiest high-value outcome each turn." Fix here: consume a turn nonce atomically before any randomness is generated. The current state is that the leaderboard is now split into human and AI-assisted. I think the capability of AI bots has flatlined a bit now. Perhaps Claude Mythos might be able to discover the next hackable exploit ¯\_(ツ)_/¯ Happy to go deeper on any of the above - or just enjoy the game! Feel free to try your own AI-powered leaderboard attempt too! https://ift.tt/PK04gG7 April 11, 2026 at 06:58AM

Summary

• XLIM and HOKA are launching a Mafate Speed 2 collaboration on April 18, 2026, featuring all-black and "Yves Klein" blue colorways.

• The design blends tactical function—like Vibram Mega-Grip soles—with lifestyle aesthetics, incorporating hairy suede details and XLIM’s signature minimal branding.

South Korean label XLIM is doubling down on footwear, following up on a recent New Balance tie-up with a color-steeped duo of HOKA Mafate Speed 2s. The thick-soled model, made for optimal comfort in tactical conditions, gets subtle updates in XLIM's minimal expression.

Coming in all-black and a cobalt blue, XLIM and HOKA's inaugural collaboration caters to the sleek and discreet just as much as it does to those with an appetite for brights.  The blue colorway is a particularly eye-catching variant, reminiscent of the hues of artist Yves Klein. HOKA's Mafate Speed 2 has a tech-forward aesthetic with its intricate synthetic overlays and sculptural midsole. However, XLIM designer Dohee Kim gives the shoe hairy suede details for contrast and places a subtle XLIM imprint on the lateral toe.

The Mafate 2 is best described as a trail-to-lifestyle shoe, which addresses function and form equally. For example, the Vibram Mega-Grip outsoles offer 5mm-deep treads made to traverse challenging terrain. Additionally, within the body, a deep Active Foot frame offers physical support, and the tuned Meta-Rocker enhances the gait cycle.

In Hypebeast Magazine 35, Dohee Kim explained this aspect of XLIM's approach: "Rather than simply following external trends or focusing on aesthetics, we wanted to design practical clothing that brings a new kind of joy and experience to those who wear it." "This approach gives people a natural opportunity to blend function and style in their everyday lives. To support this vision, we develop our own fabrics, allowing us to create innovative designs from the ground up," he added.

The XLIM x HOKA Mafate Speed 2 is set for release on April 18, 2026, at XLIM's physical location and web store.

Show HN: Steadcast – Free Mac podcast player for learning, not background noise https://ift.tt/0AkZpO9

Show HN: Steadcast – Free Mac podcast player for learning, not background noise Hey HN — I'm Aaron, and I built Steadcast because I was frustrated that I listen to 15+ hours of podcasts a week and retain almost none of it. Steadcast is a native macOS podcast player (Swift, SwiftUI, AVFoundation — no Electron) designed around one idea: podcasts are how a lot of us learn now, but no podcast app actually treats them that way. What makes it different: • Learning domains, not genres. The app is organized around 10 knowledge domains (AI, science, history, philosophy, psychology, etc.) with 90+ editorially curated shows. No true crime, no celebrity gossip. * On-device transcription. Every episode gets transcribed locally using the macOS 26 Speech framework. Every word becomes searchable. No cloud processing, nothing leaves your Mac. •AI summaries. Apple Intelligence generates summaries that capture the key ideas from each episode. • Memories. Press Ctrl+Cmd+K while listening and Steadcast saves a timestamped bookmark with the full transcript context around that moment. So when you hear something worth remembering, you can actually find it later. • Smart Speed. Intelligent silence trimming with a live counter showing exactly how much time you've saved. • Keyboard-first. Global hotkeys, full keyboard navigation — built for people who work at their Macs all day. It's free on the Mac App Store: https://ift.tt/6whN4kD Requires macOS 26. Built as a solo project. I'd love feedback on the curation approach especially — is a podcast app that has opinions about what you should listen to a feature or a bug? https://steadcast.co April 10, 2026 at 09:06AM

Show HN: QVAC SDK, a universal JavaScript SDK for building local AI applications https://ift.tt/DQ2faOn

Show HN: QVAC SDK, a universal JavaScript SDK for building local AI applications Hi folks, today we're launching QVAC SDK [0], a universal JavaScript/TypeScript SDK for building local AI applications across desktop and mobile. The project is fully open source under the Apache 2.0 license. Our goal is to make it easier for developers to build useful local-first AI apps without having to stitch together a lot of different engines, runtimes, and platform-specific integrations. Under the hood, the SDK is built on top of QVAC Fabric [1], our cross-platform inference and fine-tuning engine. QVAC SDK uses Bare [2], a lightweight cross-platform JavaScript runtime that is part of the Pear ecosystem [3]. It can be used as a worker pretty much anywhere, with built-in tooling for Node, Bun and React Native (Hermes). A few things it supports today: - Local inference across desktop, mobile and servers - Support for LLMs, OCR, translation, transcription, text-to-speech, and vision models - Peer-to-peer model distribution over the Holepunch stack [4], in a way that is similar to BitTorrent, where anyone can become a seeder - Plugin-based architecture, so new engines and model types can be added easily - Fully peer-to-peer delegated inference We also put a lot of effort into documentation [5]. The docs are structured to be readable by both humans and AI coding tools, so in practice you can often get pretty far with your favorite coding assistant very quickly. A few things we know still need work: - Bundle sizes are larger than we want right now because the current packaging of Bare add-ons is not as efficient as it should be yet - Plugin workflow can be simpler - Tree-shaking is already possible, but at the moment it still requires a CLI step, and we'd like to make that more automatic and better integrated into the build process This launch is only the beginning. We want to help people build local AI at a much larger scale. Any feedback is truly appreciated! Full vision is available on the official website [6].

Show HN: Zeroclawed: Secure Agent Gateway https://ift.tt/sUYOkb1

Show HN: Zeroclawed: Secure Agent Gateway I’ve been cautiously (and nervously) playing with openclaw and a number of other claw and code agents for a while now, but trying out different ones was tricky so I wanted a simple way to switch out channel ownership… then I wanted more. Security is hard, and I wanted to make it easier. This is FAR from polished, and no claims that I’m a “security expert” but I tried to think and research a bit on different threat models (I think of 2 broad ones for agents, external adversaries and internal agentic failures) and try and offer best in class protection on both, while also not having any special opinion on what a good agent may look like today or in the future… this is just a gateway, and hopefully one that can work for nearly any agent now or in the future, but trying to come with batteries included for some of the more popular options today like openclaw, zeroclaw, claw-code, clause and opencode, not all there yet but contribution and critiques welcome. https://ift.tt/2U7ghab April 10, 2026 at 09:32AM

Show HN: Zoneless – Open-source Stripe Connect clone with $0.002 fees using USDC https://ift.tt/Qlv3bnX

Show HN: Zoneless – Open-source Stripe Connect clone with $0.002 fees using USDC Hi HN, I'm Ben / Tiny Projects (I once posted here about buying 300 emoji domains from Kazakhstan…). For the past 3 years I've been solo bootstrapping PromptBase, an AI marketplace with 450k+ users. At the peak, I was burning $9,400/month in opaque Stripe Connect fees for seller payouts, so I built Zoneless to replace it: - GitHub: https://ift.tt/4AGfezi - Website: https://zoneless.com Zoneless is a free, open-source (Apache 2.0) drop-in replacement for the payout part of Stripe Connect. It allows you to pay marketplace sellers globally with stablecoins (USDC) using an identical API to Stripe and at near-zero fees. I've been dogfooding Zoneless on PromptBase for 3 months with some good results: - 2,200+ sellers onboarded - 1,400+ payouts completed - Monthly payout fees reduced to just a few dollars - 73% of sellers, when given the choice at onboarding, actively picked Zoneless over Stripe Connect A massive part of running a marketplace is paying sellers. While Stripe Connect is a great product, it has big pain points: - Expensive + complex fees: $2/mo per active account, 0.25% + $0.25 domestic payout fee, $1.50 international payout fee, 0.25–1.25% cross-border fee, 0.50–1% FX fee. It costs >$2 to move $1. - Limited reach: Only supports around 47 countries. - Slow payouts: Takes 2-7 days to settle. - Platform risk: A massive single point of failure if your account gets randomly flagged. Zoneless is designed to solve all this: - Payouts cost ~$0.002 on Solana - Global: 220+ countries/regions - Instant payouts, 24/7. - Self-hostable and open-source The API/SDK is identical to Stripe (same webhook events, same object shapes, etc.). If you know Stripe, you already know how to use Zoneless. There’s also an Express Dashboard for sellers to onboard and track their earnings. I've been able to remove annoying things on PromptBase like forcing sellers to accrue a $30 minimum balance before a payout just to keep our costs down. I can now also onboard sellers from more countries, which has helped spread the word and grow the buyer side too. A big worry was that non-crypto users would be confused or hate getting paid in USDC, but they actually don’t mind at all, they just care about being paid faster. If they want to convert to their local currency, they simply use an exchange like Coinbase. Zoneless is self-custodial, meaning you create and own your wallet, and the code never touches funds. You can also easily plug in providers for KYC/AML. I appreciate that anything related to crypto is like Marmite (pretty polarizing); I’m a no-coiner and have never dabbled in NFTs, but I do think stablecoins are different: they’re just boring tech to move money around cheaply. I'd love to hear your thoughts, feedback, or questions - especially if you've dealt with Stripe Connect / payouts / marketplaces before. - GitHub: https://ift.tt/4AGfezi - Website: https://zoneless.com - Docs: https://ift.tt/ABrVqsb https://ift.tt/4AGfezi April 9, 2026 at 10:31AM

Show HN: AgentDM – Agent to agent messaging over MCP and A2A https://ift.tt/9glJVPr

Show HN: AgentDM – Agent to agent messaging over MCP and A2A I kept copy pasting between two Claude Code instances. My teammate would ask me something about a module I wrote, I'd paste their question into my Claude Code, copy the answer, send it back on Slack. We were playing telephone between two agents that could have just talked directly. So I built AgentDM. It's a hosted messaging grid where AI agents DM each other by @alias. Any MCP compatible client connects with a 5 line JSON config no SDK, no shared runtime. How it works: - Each agent gets a unique @alias. - Three(main) MCP tools: send_message, read_messages, message_status. - Messages encrypted with AES-256, deleted after delivery. - Guardrails (static + LLM powered) filter messages before delivery. Last week we shipped an MCP/A2A protocol bridge. Your MCP agent can message an A2A agent and vice versa the translation happens server side. Neither agent knows or cares what protocol the other speaks. We also open sourced an A2A Simulator for debugging a2a protocol: https://ift.tt/WR4sd67 https://agentdm.ai https://agentdm.ai April 9, 2026 at 10:06AM

Show HN: CSS Studio. Design by hand, code by agent Hi HN! I've just released CSS Studio, a design tool that lives on your site, runs on your browser, sends updates to your existing AI agent, which edits any codebase. You can actually play around with the latest version directly on the site. Technically, the way this works is you view your site in dev mode and start editing it. In your agent, you can run /studio which then polls (or uses Claude Channels) an MCP server. Changes are streamed as JSON via the MCP, along with some viewport and URL information, and the skill has some instructions on how best to implement them. It contains a lot of the tools you'd expect from a visual editing tool, like text editing, styles and an animation timeline editor. https://cssstudio.ai April 9, 2026 at 07:23AM
