Mux0

English | 简体中文

  Mux0

A macOS tabbed-and-split terminal with live AI agent status in the sidebar. Organize terminals by project, split panes freely, and always know at a glance whether Claude Code, OpenCode, or Codex is running, idle, or waiting for you.

Powered by the ghostty engine with Metal GPU rendering. Bilingual UI — English / 简体中文.

Features

- Workspaces → Tabs → Splits — Organize terminals by project. Each workspace owns its own set of tabs; each tab is a split tree you can cut horizontally or vertically, drag dividers, and navigate with the keyboard.
- Live AI Agent Status — Sidebar and tab icons reflect running / idle / waiting-for-input / finished state for Claude Code, OpenCode, and Codex. Each turn is tagged success or failed. Hover an icon to see the currently running tool and (for Claude / Codex) a short summary of the agent's last reply.
- Workspace Sidebar Metadata — Every workspace row shows its current git branch, open PR status, and unread notifications — refreshed every 5 seconds in the background and updated live via OSC hooks from your shell.
- Beautiful Theming — Every ghostty theme bundled in. Adjust background opacity, window blur (vibrancy), cursor shape and blink, and unfocused-pane dimming. Mux0's own sidebar and tab bar re-tint to match the active terminal theme — no jarring chrome.
- Bilingual UI — Full English and Simplified Chinese. Switch in Settings → Appearance → Language without restarting.
- Layout Persistence — Workspace list, tab list, split layout, and each terminal's working directory survive across restarts.
- Auto-Update — In-app updates powered by Sparkle. A dot appears in the sidebar footer when a new version is ready; release notes are shown inline and you can defer or skip any release.
