Mux0

Mux0 is a native macOS terminal emulator built on libghostty and Metal for GPU-accelerated rendering. It is designed for developers who work with AI coding agents (Claude Code, OpenCode, Codex) and need real-time visibility into agent status. Key features include:

• Workspaces, tabs, and split panes: Organize terminals by project with persistent layouts that survive restarts.
• Agent-aware UI: Sidebar and tab icons show live status (running, idle, needs input, success, failed) for each agent session.
• Project-first metadata: Each workspace displays git branch, open PRs, and unread notifications.
• Full theme support: Ships with all Ghostty themes and hot-reloads edits after 200ms.
• Local-only communication: Agents report status via a Unix domain socket; no network, no cloud, no telemetry.
• Open source (source-available): Published on GitHub with a permissive license for personal and commercial use.

Target users are developers who use AI coding agents and want a terminal that stays out of the way but provides clear, glanceable information about what the agent is doing.
