Rakumux is a terminal session manager built for developers who run coding agents. Run Claude Code, Codex, OpenCode, Pi, dev servers and shells side by side, each in its own session. A small background server owns your terminals, so they keep running when you close the UI, quit your terminal or lose an SSH connection, and they come back after a reboot.
Rakumux in a terminal: the session list with each session's worktree and branch, a live Claude Code session, and the Feed on the right
楽 (raku) means easy, and read gaku it means music: tmux, made easy.

Why developers use it

Run many agents at once

Give each task its own agent, in its own folder or worktree, and keep them all running while you work on something else.

Know which agent needs you

The list opens on Status: agents waiting for your answer first, then replies you haven’t read, then the ones still working.

Sessions named for their task

Signed in, each agent session gets a short AI title from what you asked it, like Fix flaky login test.

Sessions outlive the window

Quit, disconnect or reboot: agents keep working, and Claude Code, Codex and OpenCode come back in the same conversation.

Work from anywhere

Run agents on a remote machine so they keep working while your laptop sleeps, and pick them up from any SSH login or your phone.

Let agents use it too

An MCP server, a JSON command line and a local HTTP API let agents and scripts start, read and watch sessions.

How it feels

  • One key, no collisions. Your programs keep every key but one: Ctrl-\ switches between a session and Rakumux. In Rakumux, j/k move through the sessions and each one plays live beside the list.
  • Nothing to manage. A session is just a folder and a terminal. Rakumux never runs git or creates worktrees for you; it reads each session’s branch, follows the worktree its agent is working in, and lists every checkout it changed.
  • Answer from anywhere. The Feed beside your sessions has every agent’s finished turns, from every machine; write back there or on rakumux.com, with a screenshot if you like.
  • Many windows, one set of sessions. Open Rakumux in several terminals, or over SSH and on your phone at the same time: they all show the same sessions, live.
