Features

  • Native macOS app — Built with Swift and AppKit, not Electron. Fast startup, low memory.
  • Vertical tabs — See all your terminals at a glance in a sidebar
  • Notification panel — See which agents are waiting for input at a glance
  • Notification rings — Tabs flash when AI agents (Claude Code, Codex) need your attention
  • Lightweight — Small binary, minimal resource footprint. No bundled browser engine.
  • GPU-accelerated — Powered by libghostty for smooth rendering

Install

Homebrew:

brew tap manaflow-ai/cmux
brew install --cask cmux

Or download the DMG directly.

Why cmux?

Running multiple AI coding agents? cmux helps you manage them. Instead of losing track of which terminal needs input, the notification panel shows you exactly where to look.

A native macOS app means it launches instantly, uses minimal RAM, and feels right at home on your Mac.
