Manage coding agents and tmux sessions on your Mac or Linux server from your phone. Install gtmux on your Mac or Linux server and pair your phone. Claude Code, Codex, DeepSeek Harness, 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, with text, icons and colors for 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. Permission requests and recognized choices appear in the conversation. A Keys panel supports function keys and modifier combinations. 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. • Start a new tmux session on your server from your phone. • Check available quota, reset times, account balances and recorded token usage. • 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 Mac and Linux. Connect from the phone app, terminal, browser, or gtmux attach on another computer. A menu bar app is also available on Mac. Install the server 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 server. Privacy gtmux collects no data. There is no account. Your sessions and your token stay on your device and your server. Notifications are sent by your server through a relay, which forwards them to Apple's push service without storing them.
