OCTOBER’S MOST TRENDING GITHUB REPO: REA (Reverse Engineer Anything). 86.7K ⭐️ on GitHub, +25K just today. It lets your AI agent take apart almost any app and tell you how it works. Free and open source. Here’s the idea: You see a feature you like in some app. You... ask your agent “how did they build this?” It digs into the app and explains it to you, with proof, without needing the source code. What it can open: → Mac, Linux and Windows apps → JavaScript and Electron apps → Android apps and websites → Everything runs on your computer, nothing gets uploaded → Works with Claude Code, Codex, Cursor, Gemini CLI and OpenCode Try something like: “Figure out how Discord shows who’s typing in real time, show me the proof, and build something similar for my project.” Heads up: it won’t give you the app’s original code or clone it. And knowing how something works doesn’t mean you’re allowed to copy it. How I’d use it: see how another tool solves a problem I have in my own app, find out which APIs it uses… the rest is up to your imagination. share this if you found it useful ♻️ and save it before you lose it 🔖 Repo ↓show more

github está on fire con esto

absolutely

wait what this is insane

ong!

como?? madre mia , esta repo es una completa locura

yess

reverse engineering speedrun any%

no source code needed is actually wild

i know!!

puedo usarlo con discord?

yes, i used it with discord yesterday

wonder how long until apps start shipping obfuscation just to slow down agents lol

86.7k stars for a reason

absolutely

+25k estrellas en un dia, la verdad que poco me parece para esta locura

so real

this is crazy crazy

esto es brujería pero legal

hahahah

esto es brujería pero legal

😂😂

bookmarked, testing it tonight

lmk

lo probare

lmk!!

normal que este trending esto es loco

yess

ok this is lowkey genius

its so alpha

devs about to learn so much from this

fr!

esto es como tener rayos x para apps

Hahahah literally

everything staying local is the best part

yess tbh

finally i can stop guessing how apps work

Reading how an app works was never the moat. The moat is what a reverse-engineer can't see: the data, the support history, the approvals that decide what ships. Cloning a feature is a weekend now. Running it reliably for a year still isn't.

The “show me the proof” part is what stands out. Can it reliably distinguish observed behavior from an educated guess when the app’s internals are opaque?

+25k stars in a day for a tool that takes apart any app. every saas founder reading this just felt their moat get a little shallower lol

free and open source? say less

me opening discord just to understand the typing dots

me too hahah

claude code con esto es otro nivel

Agents that can take apart any app are powerful, so the permission layer matters. Mine can inspect and propose all day, but anything that writes or sends goes through me.

my agent about to know discord better than discord devs

this is how you actually learn to code

REA can inspect Mac, Linux, Windows, Android apps, Electron apps, and websites, while keeping the analysis on your computer; that helps explain behavior without handing over source code.

The most interesting part isn't the reverse engineering — it's that REA turns every proprietary app into a free textbook. Your competitors' UX decisions, their API design, their edge cases: suddenly all readable. The real moat was never the code itself, it was the "how it works" knowledge locked inside. REA just turned that knowledge into a commodity.

people are gonna take apart so many apps with this
