Manage the coding agents and tmux sessions on your Mac from your phone. Install gtmux on your Mac and pair your phone. Claude Code, Codex, other coding agents, and ordinary terminal panes will appear on your phone, so you can follow their progress and respond while you're away from your desk. HQ (Headquarter) HQ is the command center for your agents. It follows their sessions, works out what needs your decision and what can continue, then catches you up on what changed. It acts on your behalf only within the scope you authorize, with a record of every action. As work progresses, HQ adds reusable lessons to your local knowledge base. It draws on what worked before when a similar task comes up. Your corrections and new evidence help it revise old lessons and its own approach, so it gets to know your projects and preferences over time. Session status The radar lists your panes and agents, using colors to show their status. For agents without a direct integration, gtmux can read the terminal screen to identify their state. Replies and commands Answer an agent or send a command to a terminal from your phone. Numbered choices appear as buttons. You can also bring a session to the front on your Mac. Pairing permissions control terminal input; read-only access cannot type into a pane. Other features • Get notified when an agent needs you or finishes. • Check remaining quota, the tightest usage window, and its reset time. • See the current agent's state on the Lock Screen and Dynamic Island. • Share a link limited to the sessions you choose. Revoke it at any time; input access must be enabled separately. • On iPad, the radar sits in the sidebar beside the open session, with room for HQ and pending decisions. Hardware keyboard shortcuts are supported. • Available in English and Simplified Chinese. Connecting gtmux is free and open source, and runs on your Mac. You can reach it from the phone app, terminal, menu bar, browser, or gtmux attach on another computer. Install it on the Mac first, then pair your phone. Setup guide: ccy.dev/projects/gtmux. Anywhere access can use a gtmux tunnel without a VPN. You can also connect over your own network. Agents continue running on your Mac. Privacy gtmux collects no data. There is no account. Your sessions and your token stay on your device and your Mac.
