Panes get a blue ring and tabs light up when an agent needs an answer. A notification panel collects every pending request in one list, which matters when four agents run and only one is blocked. Alerts fire through standard terminal escape sequences (OSC 9, 99 and 777), so any agent that emits them works without extra setup.

cmux splits horizontally and vertically, and the sidebar carries the git branch, linked pull request status and number, working directory, listening ports and the latest notification text for each workspace. You get the context of a tmux status line without writing the config to build it.

A real browser pane opens next to the terminal and takes orders over the same socket API as the rest of the app: navigate, snapshot the DOM, click, type, run JavaScript, read console and network activity. Agents can check their own web changes without leaving the window, and cookies imported from Chrome, Firefox, Arc and 20 other browsers mean panes start logged in.

Every action in the app is scriptable. You can create workspaces, open splits, send input, read screen contents and take screenshots from the command line or a Unix socket. That makes cmux a target for scripts and hooks rather than a window you only click around in.

cmux ssh user@host builds a workspace for a remote machine, and browser panes route through that machine's network, so a localhost URL resolves where the code actually runs. You can attach to existing remote tmux sessions, and drag an image into a remote pane to push it over scp.

Claude Code, Codex, OpenCode, Gemini CLI, Kiro, Aider, Goose, Amp, Cline and Cursor Agent all run in cmux, because cmux is a terminal and not an agent runtime. A dedicated cmux claude-teams command turns Claude Code's teammate mode into native splits with no tmux layer.
