What is cmux?
cmux is a free, open-source, native macOS terminal based on Ghostty, offering vertical tabs, notification rings when an agent needs attention, split panes, and a CLI for programming. When an agent creates subagents or teammates, it shows them in native panes instead of hidden background processes. You can open workspaces on remote machines over SSH, and paid plans run agents on cloud VMs.
- Vertical tabs show git branch, working directory, ports, and notifications
- Pane notification ring when an agent needs attention
- Built-in browser you can control with scripts
- Horizontal and vertical split panes within a tab
- CLI and socket API for automation
- iOS app with real-time sync for iPhone and iPad
- Session restore after relaunch or reboot
- SSH remote workspaces
Who uses cmux and for what
- Run and monitor multiple CLI agents such as Claude Code and Codex in parallel in one terminal
- Run agents on a remote server and control them from local cmux
