CMUX: Too Much Hype?

A hands-on critical review of CMUX (Simax), a new Mac-only terminal multiplexer built on top of Ghostty, aimed at AI agent workflows. The reviewer explores its workspace management, embedded browser tabs, notification system, CLI API, and SSH features, comparing them extensively to tmux with plugins like Sesh and Session X. While acknowledging CMUX has unique features (embedded browser, agent notifications, scriptable API), the reviewer finds it too rough around the edges, Mac-only, and not compelling for experienced tmux or Ghostty power users. The conclusion is that CMUX may appeal to newer developers forced into the terminal by AI agents, but doesn't justify the hype for seasoned terminal users.
