Transcript
cmux is a Ghostty-based macOS terminal that lights up tabs when AI agents need your attention. Built with Swift and AppKit, this GPU-accelerated terminal splits a browser alongside your code and runs remote workspaces with a single command. See all pending notifications in one place, import cookies from twenty plus browsers, and manage custom commands via a scriptable API. This free open-source terminal reads your existing Ghostty config and requires macOS.
