Features

All your boxes, one view

Automatically discovers every host in your ~/.ssh/config and lists their tmux sessions alongside your local ones.

Zero configuration

If you can `ssh host`, tm can see it. Key-based auth only — no password prompts, ever.

Fast scanning

Hosts are queried in parallel with short timeouts. Unreachable boxes are skipped silently, never block you.

Attach anywhere

Attach to a remote session over ssh -t, or switch-client locally when you're already inside tmux.

Full session management

Create new sessions on any host and kill sessions anywhere — with confirmation before anything destructive.

Tiny and readable

A single Python file built on rich. No daemon, no state, no lock-in. Read it in five minutes.

How it works

tm parses the Host entries in your ~/.ssh/config (wildcards are ignored), then runs tmux list-sessions locally and over ssh on each host in parallel, using BatchMode=yes so only key-authenticated hosts respond.

a — attach by #, name, or host:name
n — new session, on any host
k — kill a session (asks first)
r — rescan all hosts
q — quit

Commands: tm local and tm remote scope the view, tm ls lists everything and exits, tm attach <name> jumps straight into a session, tm update self-updates to the latest release, tm help shows usage.

Requirements: Python 3.8+, tmux, and ssh keys for any remote boxes.
