REA lets your AI reverse-engineer any app's features — 40K to 81K GitHub stars in 3 days
alex_verem · x · 2026-10-12
REA (Reverse Engineer Anything) lets you point your AI at a feature you like and ask how it works: it opens up the app with no source code needed, explains the mechanism with evidence, and builds a similar version for your project.
Key points:
- Works on desktop apps, Electron, .NET programs, and websites — down to native binaries
- Plugs into Claude Code, Codex, Cursor, and Gemini; runs locally on your machine
- Example: ask "how does search work in the Notes app" and it explains and shows evidence
- Built by one developer; 40K→81K stars in three days, #1 on GitHub Trending
As the author puts it: a small team can now study the best apps in the world in an afternoon — and so can every competitor studying yours.
