About

cmux is a native multitasking terminal built specifically for macOS, powered by the high-performance Ghostty engine. It goes beyond being just a terminal emulator—it's a workflow management tool designed for modern developers. With deep integration for Claude Code, Codex, and other popular CLI tools, cmux lets you manage multiple tasks in a single window using vertical tabs, a notification ring, split-screen panels, and a Socket API. Say goodbye to constant window switching and keep everything in one place.

Key Features

Vertical Tabs: Create multiple vertically stacked tabs within the terminal window, each running its own command or session for quick visual scanning.

Notification Ring: A non-intrusive circular notification alerts you when background tasks finish or need attention, so you don't have to keep your eyes glued to the screen.

Split-Screen Panels: Split a single tab horizontally or vertically to run tasks side by side—for example, compiling code while watching logs.

Socket API: A programming interface that lets scripts or external tools dynamically control cmux tabs, panels, and notifications for deep automation.

Claude Code & Codex Integration: Native support for AI coding assistants, allowing you to invoke Claude Code or Codex directly in the terminal for code generation, review, and debugging.

Who It's For

cmux is built for full-stack developers juggling frontend builds, backend services, database queries, and Git operations—where split panels and vertical tabs make a real difference. It's also a great fit for AI-assisted coders who rely on Claude Code or Codex and want smoother integration, plus DevOps engineers managing multiple servers or monitoring log streams without missing critical alerts. And if you're a macOS user who simply wants fewer window switches and more focused command-line work, cmux is designed with you in mind.
