Score: 7.3/10 (Innovation: 6, Technical: 8, Documentation: 8, Utility: 7)

Codebuff (and its free ad-supported version Freebuff) is an open-source AI coding assistant that uses a multi-agent architecture to edit codebases via natural language, coordinating specialized agents for file picking, planning, editing, and review. Its interesting approach of composable custom agents with TypeScript generators, support for any OpenRouter model, and a novel ad-supported free tier sets it apart from single-model tools like Claude Code.

Target audience: backend devs, frontend devs, full-stack devs
