Remote control for coding agents · Beta

Leave the desk. Keep the agents moving.

Your coding agents keep working on your machines. C3 Mobile is the end-to-end encrypted remote that lets you answer permission prompts, send the next instruction, and watch live terminals from your phone — across every machine you own, through a hub you host yourself.

See what needs you. Unblock it in seconds.

The Signal screen maps every machine and queues the agents blocked waiting on a decision. Open one and you're in its cockpit: read the state, answer the permission prompt, send the next instruction.

Mobile / Workspace

Real workspaces. A real terminal.

Drive the workspaces your agents live in — create workspaces, tabs, and panes on any connected host — and attach to any pane as a live streaming terminal that re-flows to your phone.

Mobile / Trust

One encrypted line to a hub you own.

A single foreground connection to your self-hosted hub reaches every machine. Payloads are sealed end-to-end between phone and host — the hub routes ciphertext, and push notifications never carry content.

Read the documented trust model before exposing services remotely.
