Show HN: Pulpie – Models for Cleaning the Web
Hey HN, I'm Shreyash, founder of Feyn. We built Pulpie, a family of Pareto optimal models for cleaning the web. Pulpie strips boilerplate (ads, footers, sidebars) from raw HTML and returns just the main content as HTML or Markdown. We match SOTA extraction quality while being 20x cheaper. Cleaning 1 billion webpages costs $7,900 with Pulpie versus $159,000 with Dripper, the current leading extractor. The gains come from architecture. Today's leading extractors are decoders that generate output o

Show HN: Cona – design your real room in 3D, in the browser
Hey HN! I've been working on this idea for around 9 months and want to know your opinion on the concept and the experience. I came up with it when I moved in with my girlfriend and we had a hard time making our small studio work. In Cona, you can draw your floor plan with real dimensions, scan your room, or pick from a template, then design it with real, purchasable items. It's free and there's no sign-up to try it. I wanted to build something that helps people like me actually live in the space

Show HN: Tetris where every pixel is another Tetris (23,040 games in GLSL)
On this page there are two complete recreations of the original Gameboy Tetris game based on the commented assembly code. On the top level there is a C version that compiles to WASM but on every pixel of that version there is a GLSL shader also implementing the complete original code with a AI player making virtual inputs! Everything was planned by me and coded by Claude Fable. Brazilian tileset generated by Gemini so I'm not technically using any copyrighted assets. Link to repo: https://github

Show HN: Nectar, a Rust-like React that compiles to WebAssembly
After a pretty rough gig experience, I wanted to remind myself that I was a vaguely capable developer. I had recently jumped on the Rust train and wanted a Rust equivalent of React that is more performant and easier to work with. I also wondered if I could effectively eject Javascript. This project came from that... Nectar is a programming language that compiles your entire app, logic, state, and rendering, to WebAssembly. JavaScript is reduced to a roughly 10 KB syscall layer that only bridges

Show HN: Keyhole – Share secrets with your AI agents
I had the idea for Keyhole while bootstrapping a bunch of small services and apps. I'm trying to prototype fast, and sometimes these need a variety of secrets. I use Doppler to remove myself from the loop, but once in a while I still need to provide a secret. AI agents will suggest you rotate a secret once it's been shared in a chat. I thought it would be a cool experience to let your agent ask for secrets without having them dumped in the context. The agent runs a command, a form pops up in my

Show HN: Agent Draw: An agent draws while you talk, built on TLDraw
We recently built 2draw, a Drawful-style game where players draw on a shared canvas and race to guess each other's drawings, on tldraw, an infinite-canvas SDK for React. We started wondering what it would take to put an agent in that loop, as an opponent or a rival guesser, and dug into how an agent could read and draw on a tldraw canvas. That research turned into: Agent draw, a tool that lets an agent draw to the canvas for you while you present. You can try it right now, or grab the source: -

Show HN: AI harness for C/C++ with GDB, sanitizers, perf and compile tools
hey guys, i wanted to show one of my side projects. The idea is a coding harness (independent of models) natively designed for C/C++ developer workflows. I'm a C++ dev and do not find claude code work well with C++ toolchain like gdb and perf. The current version has integrations for gdb, clang-tidy, cppcheck, sanitizers, perf, benchmarking, compile DB navigation, Godbolt, symbolization, binary inspection, and decompilation. It supports Anthropic, OpenAI, Gemini, and self-hosted models. There ar

Show HN: Homegames. An open-source game platform I've been making for 8 years
I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as t

Show HN: Tool for Auditing Embedded Linux Hosts
I just shipped a major new feature to my embedded linux auditing tool - the ability to audit the kernel on embedded hosts. The agent that runs on the embedded host sends kernel information to the companion APIs, which then build a compatible kernel module that then gets loaded by the agent on the target host. Then the agent can communicate with the kernel module to do things like read/write physical memory, convert virtual addresses to physical address, etc.

Show HN: Osint tool that finds exposed files on domains
hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to r
