Awesome REA: Reverse Engineer Anything with AI

English · 简体中文

What AI agents reverse-engineered and rebuilt, and which ones really used REA.

Unofficial. Not affiliated with morluto/rea.

"REA" started as morluto/rea (Reverse Engineer Anything, 200k+ stars), an open-source MCP server and CLI (npm rea-agents) that lets coding agents inspect native binaries, Electron apps, .NET assemblies, APKs, firmware and websites without their source code, explain how a feature works with evidence, and rebuild it. REA itself does not decompile; it orchestrates Hopper, Ghidra, IDA and JADX for the agent.

"REA" now also names the whole wave of AI agents reverse-engineering and rebuilding closed software, whether they use REA, or Claude Code and Codex with Ghidra or IDA MCP. This list covers that wave and says what each case actually used.

Tags

• REA: the project README, the author's post or the official showcase says morluto/rea was used.
• AI-RE: AI reverse engineering with other tools, or with no tool named.
• Rebuild: clean-room rewrite with no reverse-engineering evidence.
• Claim?: not yet verified.

Official showcases

These are on rea.tools and are tagged REA, except where noted.

• DX-Ball: sound-pan function - One helper that maps sound position to left/right channels, rebuilt as C. It matches 3,205 original x86 test cases, and 63 bytes match after recompilation. This is one function, not the whole game.
• Notion: Electron clipboard bridge - Traces a copy from the page API through preload and IPC to the main process.
• TH04: DOS bullet-ring maths - 16-bit angle helpers from Touhou 4 on PC-98. REA made a fresh inspection for the page; the reconstruction comes from the TH04 project.
• Aegis: login-code generation - Traces TOTP code generation in the Aegis 3.4.3 Android app.
• CTF: flag checker - A DownUnderCTF 2023 reverse-engineering challenge.
• Blog: the industrial revolution in reverse engineering - Written by N0zoM1z0, who also co-builds REA. Most of the work was done by agents with IDA / Ghidra; REA supplied only part of the evidence. Tagged AI-RE.
• Blog: does reverse engineering need a bigger model? - Discusses model capability using Touhou examples and proposes a comparison, but reports no measured results. Tagged AI-RE.

Games and reconstructions

• N0zoM1z0/dx-ball - REA Reconstruction of English DX-Ball 1.07 in C/C++, which the README says used REA. Alpha, MIT. The author is also a contributor to REA, so this is a first-party case.
• N0zoM1z0/th04 - REA (showcase) Source reconstruction of Touhou 4 (PC-98), built on ReC98 and checked against Turbo C++ 4.0J. The README does not mention REA; see the showcase above. MIT.
• N0zoM1z0's Touhou series: th08, th105, th095, th09, th10, th08-web, and touhou-reconstruction-factory - AI-RE Agent-driven reconstructions using Codex or GPT-web with IDA MCP or Ghidra. None of these READMEs mentions REA.
• ucodia/desktop-games-nostalgia - REA Port of the 2000 Gemtree Desktop Games to macOS and the browser, built with Claude Code, REA and Ghidra. No license file.
• tuunanet/rea-ski-or-die-reconstruction - REA Rust + SDL2 rewrite of the 1990 DOS game Ski or Die. Assets come from your own copy.
• Moxnatiy/OpenBattlefield2 - REA C++20 clean-room reimplementation of the Battlefield 2 Refractor 2 engine. REA is documented in CLAUDE.md and tools/rea.sh, not the README. Needs the original game. MIT.
• OpenRsG/GunZRs - REA Rust + Bevy rewrite of GunZ: The Duel, reading the Steam install. The executable is packed, so REA's role in the port is limited. Apache-2.0.
• a-barzanti/ai-rebuilds - REA Community collection of abandoned games rebuilt for the browser. Contributors use REA to write specs, then build from those specs. Ground rules forbid committing original game files.

Apps and tools

• michaelshimeles/paper-rs - REA Infinite-canvas design app in Rust (wgpu + egui), built after studying Paper's behaviour with REA and Claude Code.
• michaelshimeles/rec-rs - REA Rust screen recorder for macOS, after studying OBS Studio's architecture (OBS is GPL-2.0).
• michaelshimeles/terminal-rs - REA Bloomberg-style trading terminal in Rust. Chart behaviour was studied from public TradingView pages. No license file.
• az9713/wispr-flow-rea-teardown - REA Teardown of Wispr Flow's voice pipeline. Each claim is marked proven, inferred or hidden, plus a 64-line local rebuild. The README does not link morluto/rea; it follows a tutorial video.
• iammukeshm/hexgrab - REA .NET 10 colour picker written from REA's findings on PowerToys' shipped binaries. MIT.
• AdamLinCodes/AdamTerm - REA Minimal macOS terminal (SwiftTerm) after studying Ghostty with REA. No license file.
• JimLiu/baocut - REA (author's post) BaoCut app, whose slides editor is adapted from Claude Slides. The README does not name REA. Source-available (BaoCut Community License 1.0), not open source.
• LilZeeCN/zee-rp - REA (author's reply) CLI and MCP for reading and writing Axure RP .rp prototype files. Validated only on macOS with Axure RP 11. MIT.
• wquguru/cameo - Claim? The linked repo is the author's original desktop-pet app, not REA output. The author's follow-up post describes an REA-based reconstruction, but its source was not published.
• lxistired/ledger-reborn - REA Independent local accounting app, built after studying QuickBooks Desktop for Mac 2024 trial with REA. See discussion #2198. Preview release. MIT.
• KarlssonChristoffer/DiskLens - REA WinDirStat-style disk analyzer for Windows 11, written by Claude Code. The author used REA to study the shipped WinDirStat 2.5.0 binary first. The author says the code has not been reviewed, so treat it as experimental.
