Open source AI reverse engineering tool REA surpasses 100,000 stars on GitHub in one week
The free and open-source tool REA (Reverse Engineer Anything) saw its star count on GitHub rise from less than 10,000 on October 6 to over 100,000 by October 12, with more than 30,000 added in a single day on October 11. This tool integrates AI programming assistants like Claude Code and OpenAI Codex with professional reverse engineering suites like Ghidra, bridging the model context protocol MCP launched by Anthropic. Since its creation in April of this year, REA had long gone unnoticed; its readme file states that the tool does not claim to restore original source code or automatically clone applications, nor does it come with a decompiler.REA has been used for various reverse engineering attempts on software and games: players have made Spider-Man swing through Gotham City in "Batman: Arkham City," someone stuffed about 1,600 items from "Minecraft" into "Elden Ring" to battle Boss Malenia, and mod authors have brought firearms and menus from "Escape from Tarkov" into "The Elder Scrolls V: Skyrim." Old console exclusives are also breaking free from their platforms; in September, enthusiasts used open-source AI models and recompilation tools to bring "Fable 2," which had never been released on PC, to Windows, with AI completing the startup in about an hour, followed by a long manual fix; another developer has made "GTA 5" run natively and smoothly on iOS.
