CONFIRMED: the open-source project REA, short for Reverse Engineer Anything, became one of GitHub's most talked-about repositories in October 2026 by connecting AI coding agents to professional reverse-engineering tools. Created in April 2026 by the developer known as morluto, the project went almost unnoticed for months before exploding in early October: it had fewer than 10,000 stars on October 6 and had passed 300,000 by mid-month, according to reports from the time.
What REA does — and what it does not do
In practice, REA is a Model Context Protocol (MCP) server with a command-line interface that lets agents such as Claude Code, Codex and Cursor inspect software without access to its original source code. It gives the agent access to established tools such as Ghidra, IDA Pro and Hopper to analyze native binaries, JavaScript and Electron applications, .NET assemblies, Android apps, websites and firmware. The central point, stressed by nearly every analysis, is that REA ships no decompiler of its own: it organizes, runs and records the evidence, and the reasoning is left to the agent.
That also defines the tool's limits. REA does not recover a program's original source code and cannot clone complex software on its own. GitHub stars measure attention, not installs or real use — and the reports themselves warn that copying or analyzing commercial software can run into contracts, copyright and anti-circumvention rules that vary by country. Analysis runs on the user's machine, but the results pass through the AI agent's provider.
Why the games world joined the conversation
Among the most discussed uses are reconstructions of classic games: the project's official site lists demonstrations such as the rebuild of DX-Ball, a 1996 game, and the source reconstruction of Touhou 4, validated with replay comparisons. For developers and preservationists, the promise is to speed up studying how an old game works — useful for restoring, porting and modding titles the user already owns. The flip side is that the same techniques can copy features from other people's products, which keeps the legal debate open.
The wave continues: from software to objects
The phenomenon is already spawning spin-offs. On October 24, developer Marco Franzon presented on X the print3d plugin, described by him as “REA for objects”: from an idea, photo or product listing, the agent writes a Blender script, checks the mesh and slices it for printing on Bambu Lab printers. This information, classified here as a STATEMENT by the author picked up by specialist press, shows how the “agent + specialist tool” format is spreading beyond software. Likewise, Perplexity CEO Aravind Srinivas announced on October 16 that the REA skill now ships with Perplexity Computer — another public STATEMENT, not an independently verified fact.
The prediction by Amjad Masad, CEO of Replit, that “all software will eventually become open source” because of this kind of tool is SPECULATION: an executive's reading of the future, not a demonstrated consequence. What is confirmed so far is more modest, but no less significant: the barrier to understanding how a program works has dropped sharply — and the discussion about what to do with that knowledge is only just beginning.
