the hottest open-source agent this week isn't a coder, it's a reverse engineer. morluto's rea repo, up 7.7k stars on github in a day, reverses app behavior down to native binaries from a chat prompt.
the debugger just became a prompt conversation.
Context
The morluto/rea repository on GitHub describes itself as 'Reverse engineer anything with agents, from app behavior down to native binaries.' It is MIT licensed, was created on April 14, 2026, and showed 16,758 stars and 1,749 forks when read. The README presents it as one MCP server for reverse engineering across binaries, applications and runtime behavior.
The project site says to use REA with a coding agent to inspect binaries, trace application code and observe runtime behavior, with setup through npx rea-agents@latest setup. The README adds that native analysis can use an existing Hopper or Ghidra installation.
The repository and its description match the note. 'Up 7.7k stars in a day' is unsupported here, not refuted: the pages read show a total star count at one moment and no daily history, and a directory site shows a different total from a different date.
'From a chat prompt' fits the way the project works, as an MCP server that a coding agent calls, but it is the agent that runs the analysis. It also relies on engines such as Hopper or Ghidra for native work.
'The hottest open-source agent this week' and 'the debugger just became a prompt conversation' are the author's lines.
