Mux0

Mux0 is a native macOS terminal built for developers who run multiple coding agents across multiple repositories. It combines a GPU-rendered libghostty terminal with project-first workspaces and live status for Claude Code, OpenCode, and Codex sessions.

Key Features

• Agent-aware status — see whether each agent is running, idle, waiting for input, successful, or failed directly from the sidebar and tab bar.
• Project-first workspaces — organize tabs and split panes by repository, with branch, pull request, and notification context.
• Native performance — uses libghostty on Metal for low-latency rendering without an Electron runtime.
• Flexible split panes — create horizontal and vertical splits, resize them, and move between panes with keyboard shortcuts.
• Persistent layout — restore workspaces, tabs, split trees, and working directories after restarting the app.
• Local integration — agent hooks communicate through a Unix domain socket; no account, cloud service, or telemetry is required.
• Customizable terminal — supports Ghostty themes and settings, zsh, fish, bash, OSC 7, and live appearance updates.

Best For

Mux0 is designed for macOS developers who coordinate several AI coding sessions at once and need to know which repository or agent requires attention. It supports macOS 14 or later, with Apple Silicon recommended. The app is free to use under its source-available license.
