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. ## Full article daily.dev links to this article rather than hosting it.
