Cmux Reviews — Discover what people think of this product.

cmux is a native macOS terminal environment built specifically for multitasking with AI coding agents and complex command-line workflows. Powered by libghostty for GPU-accelerated rendering, it delivers a smooth, low-latency experience while adding a modern, opinionated interface that organizes multiple projects, panes, and agents without the overhead of tmux-style configuration.

Developers can monitor several AI copilots and long-running processes at once using vertical tabs that surface git branches, working directories, forwarded ports, and notification snippets at a glance. Notification rings highlight panes that need attention, with badges and desktop alerts triggered via standard OSC escape sequences or the cmux CLI, making it ideal for Claude Code, Gemini CLI, Aider, and other agentic workflows. A built-in scriptable browser lets you dock documentation, dashboards, or local web apps alongside your terminal, controlled via a programmable API for advanced automation.

Built with Swift and AppKit, cmux feels like a first-class macOS citizen, avoiding Electron bloat while offering extensive keyboard shortcuts for workspaces, splits, the embedded browser, and notification controls. A socket API and CLI hooks enable deep integration with existing scripts, repos, and AI agents, so you can orchestrate multi-pane sessions, automate layout setup, and keep every agent visible and responsive in a single, unified workspace.

For engineers juggling multiple repositories, LLM agents, and CLI utilities, cmux becomes a focused command center that replaces scattered terminal windows and brittle tmux setups with a cohesive, scriptable interface tuned for modern AI-driven development.
