mux – A tmux Session Manager That Turns AI Coding Sessions into Live Previews

It's a TUI-based session manager designed to solve the problem of losing track of progress when using AI CLIs like Claude Code, Aider, and Gemini across multiple tmux sessions simultaneously.

Its key features are as follows:

• Session live preview: Before switching sessions, you can preview the actual terminal output of each session.
• Automatic AI CLI detection: It automatically distinguishes and displays claude, codex, aider, and gemini sessions.
• Git info display: It shows the Git branch and worktree each session is working on.
• Popup mode: You can call up the overlay UI with a keyboard shortcut even while an AI CLI is running.

It's built with Go and Bubble Tea, and can be installed via brew install lunemis/tap/mux.
