worktree-mux

A tmux control panel for git worktrees.

When you run multiple AI agents or parallel feature branches, each git worktree becomes its own dev environment. worktree-mux maps 1 worktree → 1 tmux window, so you can instantly jump between contexts to run commands, inspect logs, or debug — without losing your place.

• What it does: fast terminal access to every worktree
• What it doesn't do: create or manage worktrees — git still does that

Think: a dashboard for parallel coding environments.

See PLAN.md for assumptions and design considerations.

Install

# Install from PyPI
uv tool install worktree-mux

# Or install from source
git clone https://github.com/tt6746690/worktree-mux.git
uv tool install worktree-mux/

# (Optional) Short alias — add to ~/.zshrc 
alias wm='worktree-mux'

Usage

1. Create worktrees with git: worktree-mux just views them

git worktree add .worktrees/feature/auth -b feature/auth
git worktree add .worktrees/fix/parser-bug -b fix/parser-bug
git worktree add .worktrees/refactor-models -b refactor-models

2. See all worktrees and their status with worktree-mux (or worktree-mux ls)

worktree-mux — my-repo (3 worktrees, 1 open)
────────────────────────────────────────────────────────────────

    Branch              tmux  Modified   vs main   Last Commit
    ──────────────────  ────  ────────   ───────   ─────────────────
  ▸ feature/auth        ●     2 files    ↑3        12 minutes ago
    fix/parser-bug      ○     clean      ↑1        2 hours ago
    refactor-models     ○     3 files    ↑5 ↓2     35 minutes ago

  ● = tmux window open    ○ = no tmux window    ▸ = current

3. Jump into a worktree: creates a tmux window and switches to it with worktree-mux cd

worktree-mux cd auth             # (fuzzy) leaf name match
worktree-mux cd parser           # (fuzzy) substring match
worktree-mux cd feature/auth     # exact path match
worktree-mux cd                  # go to the main window (repo root)

Return to your previous session: prefix + s and toggle

4. Live dashboard of worktrees — auto-refreshing version of the status table with worktree-mux dash

worktree-mux — my-repo (3 worktrees, 1 open, refreshes every 5s)
──────────────────────────────────────────────────────────────────────

    Branch              tmux  Modified   vs main   Last Commit
    ──────────────────  ────  ────────   ───────   ─────────────────
  ▸ feature/auth        ●     2 files    ↑3        12 minutes ago
    fix/parser-bug      ○     clean      ↑1        2 hours ago
    refactor-models     ○     3 files    ↑5 ↓2     35 minutes ago

  ● = tmux window open    ○ = no tmux window    ▸ = current

5. Cleanup: worktree-mux automatically cleans up orphaned tmux windows (from removed worktrees) on every command. No manual close needed — just delete the worktree with git worktree remove and the window goes away.
