Shell Online lets a terminal session running on your own computer follow you to any browser, so your coding agent keeps working while you are away from your desk. Prefix the command you already run, such as shell claude, shell codex, or shell opencode, and your terminal prints a link, a password, and a QR code that open the same live session on a phone, tablet, or another computer. You watch output as it happens and reply to prompts from wherever you are, and closing the browser leaves the process running until it exits on its own. Inviting a teammate takes the same link: share it read-only so they can watch without typing, or let them type into the session with you. Terminal traffic is end-to-end encrypted by default, file access stays off until you deliberately expose a chosen directory, and a scoped MCP grant can let another agent inspect or steer a session for a limited time. With an account, linked machines and their sessions gather in one web app with team sharing. The relay the sessions pass through can run on your own server with the standalone Docker deployment, pointed at by the unchanged CLI.
