botmux

Given the limited evidence—only the GitHub repository with 563 stars and 108 forks—botmux is worth evaluating for teams heavily invested in Feishu/Lark, but its reliability and broader utility remain unverified by independent reviews or tutorials.

It acts as a message-to-CLI bridge: each Feishu direct message, group chat, or thread launches an independent CLI session for tools like Claude Code, Codex, Gemini, or OpenCode, streaming back results as interactive cards and web terminals. Typical use cases include collaborative coding, AI-assisted code review, and side-by-side model comparison.

The setup requires a Feishu/Lark application configuration and dependencies on tmux and tailscale. The tool itself is free and open-source (stated in the official repository), but there is no cloud offering—users must provide their own infrastructure. This is not a plug-and-play bot or a graphical AI assistant; a closer analogy is a multiplexing bridge that turns chat messages into isolated multi-model terminal sessions.

Adoption evidence is limited to GitHub stars and forks, which only indicate interest, not proven effectiveness.
