REA

REA is a software development tool that reverse engineers apps, binaries, and browser behavior with a coding agent.

REA is a reverse engineering tool designed to work directly with your coding agent. It allows users to inspect native binaries, JavaScript applications, Electron apps, and browser activity using plain English prompts. The tool reads running scripts, installed programs, and executable files, returning decompiled code, function calls, and settings to the agent. Users can investigate how software works, recover specific rules, and rebuild features or small versions of applications. It supports targets like Windows Calculator and browser games, helping developers understand branch logic, math rules, and application code.
