Ghostty-based terminal with vertical tabs and notifications
SMRTR summary
cmux is a native macOS terminal app built with Swift that enhances Ghostty with vertical tabs and notification rings designed for AI coding agents. When agents like Claude Code need attention, panes get blue rings and tabs light up in the sidebar, solving the problem of tracking multiple parallel AI sessions. The app includes an in-app browser with scriptable API and maintains Ghostty compatibility.
