REA hits 110k GitHub stars as AI agents reverse-engineer commercial software feature by feature
创业邦 · wechat · 2026-10-15
The GitHub project REA (Reverse Engineer Anything) has passed 110k stars. It lets agents like Claude Code and Codex drive tools such as Ghidra, Hopper and IDA to reverse-engineer software features from binaries, runtime behavior or network traffic, then rewrite them — no source needed. Documented cases include rebuilding an authenticator algorithm (133/133 tests match), tracing Notion's clipboard copy path, rewriting a DX-Ball sound-positioning function in C (3,205 tests match, byte-identical 63-byte machine code), and Touhou danmaku math — governed by a SKILL.md methodology requiring evidence-based tracing and output comparison. Spillovers: classic games ported to browsers, a 596-day ROM reverse reduced to 84 days, and VibeOffice recreating Office 2003 in-browser for $1,000+ in tokens. The piece weighs the legal gray zone and the threat to software pricing moats, hitting single-purpose utilities first.
