REA, the Viral Reverse Engineering Tool: Should Lazy People Install It?

In the past two weeks, the hottest project on GitHub is probably REA (Reverse Engineer Anything). On 10/6, it had not even 10,000 stars; by 10/17, it had over 290,000.

What is REA? Simply put, it equips AI with a full set of tools for "taking apart software." Its goal: see a useful feature in someone else's software → take it apart to understand how it works → make your own version. And no source code needed. Not just mobile apps; Windows/Mac desktop software, websites, old games, firmware, and network packets can all be taken apart.

Official cases it has taken apart: ・How a mobile verification app calculates its 6-digit login code and why it changes every 30 seconds ・The sound effect algorithm of the 1996 old game DX-Ball, restored into a 63-byte program, compared byte-by-byte with the original ・In the Notion desktop version, after you press "Copy," how the data travels all the way to the clipboard ・How bullets in the PC-98 old game arrange themselves in a circle to aim at you ・CTF puzzle solving: after taking it apart, it also uses the original program to verify the answer

Pros ✔ Install with a single command; works with Claude Code, Codex, and Cursor ✔ Connects to 170 tools at once ✔ Every conclusion comes with evidence, and uncertain points are also written out
