cmux is a Ghostty-based macOS terminal designed for developers who work with AI coding agents. It combines a terminal, browser, notifications, workspaces, panes, tabs, and a CLI into one agent-friendly environment. The project does not force a specific agent workflow, but instead provides primitives that developers can use to coordinate their own tools. Vertical tabs and workspace organization make it easier to track multiple agent sessions or coding contexts at once. Built-in notifications help users notice when long-running agents or commands need attention. cmux is best suited for macOS developers who use terminal-based AI coding tools and want a more organized, interactive control surface around them.
