Install

npm install -g dmux

Quick Start

cd /path/to/your/project
dmux

Press n to create a new pane, type a prompt, pick one or more agents (or none for a plain terminal), and dmux handles the rest — worktree, branch, and agent launch.

What it does

dmux creates a tmux pane for each task. Every pane gets its own git worktree and branch so agents work in complete isolation. When a task is done, open the pane menu with m and choose Merge to bring it back into your main branch, or Create GitHub PR to push the branch and file a pull request.

• Worktree isolation — each pane is a full working copy, no conflicts between agents
• Agent support — Claude Code, Codex, OpenCode, Cline CLI, Gemini CLI, Qwen CLI, Amp CLI, pi CLI, Cursor CLI, Copilot CLI, and Crush CLI
• Goal launches — optionally start supported agents in goal mode from the initial prompt
• Multi-select launches — choose any combination of enabled agents per prompt
• AI naming — branches and commit messages generated automatically
• Smart merging — auto-commit, merge, and clean up in one step
• macOS notifications — background panes can send native attention alerts when they settle and need you, with a global off switch
• Built-in file browser — inspect a pane's worktree, search files, and preview code or diffs without leaving dmux
• Pane visibility controls — hide individual panes, isolate one project, or restore everything later without stopping work
• Multi-project — add multiple repos to the same session
• Lifecycle hooks — run scripts on worktree create, pre-merge, post-merge, and more

Git Branch Controls

dmux can use default branch behavior or let you override branch details when creating a pane.

• Keep the default flow for fast creation, where dmux automatically picks the worktree and git branch names.
• Optionally choose a different base branch per pane.
• Optionally provide an explicit branch/worktree name (useful for issue-tracker ticket naming).
• Multi-agent launches still use shared naming with agent-specific suffixes.

Keyboard Shortcuts

Requirements

• tmux 3.0+
• Node.js 18+
• Git 2.20+
• At least one supported agent CLI (for example Claude Code, Codex, Grok Build, OpenCode, Cline CLI, Gemini CLI, Qwen CLI, Amp CLI, pi CLI, Cursor CLI, Copilot CLI, Crush CLI)
• OpenRouter API key (optional, for AI branch names and commit messages)
