Observer — scan your code for security issues, 100% offline
What it does
Worried about uploading source code to the cloud? Observer is an offline, privacy-first scanner for Go, PHP, Python & JS. It catches security and quality bugs with no account and no upload — your code never leaves the machine. The built-in engine runs instantly; optional Semgrep & PHPStan go deeper, 100% locally. A dashboard shows health + security scores. Free on GitHub; Pro unlocks extra engines.
Finds what's wrong — and shows you the fix. Code, deps, config & infra — one offline scan, one report. - sanks205/getobserver

This project (Agents Observe) started as an exploration into building automation harnesses around claude code. I needed a way to see exactly what teams of agents were doing in realtime and to filter and search their output. A few interesting learnings from building and using this: - Claude code hooks are blocking - performance degrades rapidly if you have a lot of plugins that use hooks - Hooks provide a lot more useful info than OTEL data - Claude's jsonl files provide the full picture - Lifecycle management of MCP processes started by plugins is a bit kludgy at best The biggest takeaway is…

- SOSighthound - open-source vulnerability scanner for source codeJul 2026 · github.com · ▲19
We're open-sourcing Sighthound today, our rules-based static security scanner. What makes it special is that it's coded in rust and uses tree-sitter as it's AST making it very fast and easily extensible. Why build another scanner in 2026? We wanted to improve some of our detection outcomes but noticed the current open source scanners like Semgrep/Opengrep we're capped by a bunch of adoption limitations such as being written in OCaml, requiring a lot of work to add a language parser, and the rulesets were licensed differently and required paid offerings. It also felt that licensing was…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
