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 Swift/Appkit.

Introducing cmux history:

cmux now has support for reopening closed terminals/browsers/workspaces via ⌘+Shift+T

History also supports reopening closed Claude Code/Codex/OpenCode/etc sessions

You can also jump back and forward through recently focused workspaces/terminals with the navigation buttons or ⌘+[ and ⌘+] (similar to a browser)

Run `cmux hooks setup` once

Out in 0.64.11
