Brief

cmux is presented as a purpose-built terminal for multi-agent coding workflows around Claude Code. The pitch centers on reducing missed handoffs and context switching with pane-level attention indicators, notifications, vertical tab management, and an in-terminal browser, while emphasizing a native Ghostty-based implementation instead of an Electron or Tauri app.

A dedicated terminal "cmux" made by my ridiculously talented friends, for hardcore Claude Code enthusiasts You can open browsers within the terminal, get notifications, highlight agents waiting for responses, and it's packed with all sorts of handy features. Plus, being based on Ghostty is super cool! (Actually, since I'm a huge tmux fan myself, I helped with naming cmux 😎)

Quoting @lawrencecchen

Introducing cmux: the open-source terminal built for coding agents.

  • Vertical tabs
  • Blue rings around panes that need attention
  • Built-in browser
  • Based on Ghostty

When Claude Code needs you, the pane glows blue and the sidebar tells you why.

No Electron/Tauri. Just
