## Best for

Developers and security researchers who want an agent to explain how an app or binary actually works.

## Why it deserves attention

REA packages reverse-engineering workflows as an MCP server and agent skill: point Claude Code, Codex, or another agent at an app, and it can inspect behavior, trace execution, and move down to native binaries with evidence for each conclusion. It supports macOS, Linux, and Windows targets and integrates with tools such as Hopper and Ghidra. It is MIT licensed with roughly 426,000 GitHub stars and daily commits. Only use it on software you are authorized to inspect, and treat generated findings as leads that still need verification.
