About
cmux is a native terminal built on libghostty for people who keep several Claude Code or Codex sessions going side by side. A vertical sidebar shows each workspace's git branch, pull request, working directory and listening ports, and a pane lights up with a ring when its agent is waiting for you. It adds splits, a built-in browser that agents can drive, SSH workspaces, and a CLI and socket API for scripting all of it, while reading your existing Ghostty config for themes and fonts. Free and open source.
