REA reverse-engineers any app. I built REAShield to make it come back empty

A developer built REAShield, an open-source hardening harness that runs the trending REA reverse-engineering agent against an app before and after defenses are applied and scores how much it recovers. The tool moves secrets off-device, seals them as ciphertext, or compiles them into WebAssembly that REA's static analysis cannot traverse, aiming to drive automated recovery to zero. REAShield is installable via npm for JavaScript and Electron apps and pip for Python.

Right now the 1 trending repo on GitHub is REA https://github.com/morluto/rea — Reverse Engineer Anything . 335K+ stars. It lets anyone point an AI agent at your shipped app and rebuild any feature. No source code. One command. It's already a one-prompt skill inside mainstream AI tools. The whole internet's reaction has been some version of: "software is dead," "your app is exposed," "every competitor can clone you now." They're right. And in a week of 100K+ developers rushing to use REA to open other people's apps, I noticed something: nobody built the defense. So I did. It's called REAShield — the direct counter to REA. The name says the whole thing: REA opens apps, REAShield closes yours. No hand-waving. REAShield ships a harness that runs the actual REA against your own app, before and after hardening, and scores what it recovers. On my test app: Because the secrets weren't obfuscated. They were gone : moved off-device, sealed as ciphertext, or compiled into WebAssembly REA can't walk. REA is static — it never runs your app, and it leaves anything runtime-computed "unresolved." REAShield weaponizes exactly that: npm i -D reashield npx reashield build npx reashield test --rea Run REA on your app before and after. Watch the recovery number drop to zero. JS, Electron, and Python: pip install reashield . Offline code is never unbreakable . If a machine runs it, it has it; a determined human still gets there. REAShield's job is to defeat the automated attack — the one REA just handed to everyone — and raise a human's cost from minutes to days. REA made reverse-engineering a one-command skill. REAShield makes the defense one too. https://github.com/HMAKT99/reashield https://github.com/HMAKT99/reashield — point REA at it and try to break it.
