Your pi agent is mid-refactor on the server at home, you are on a train with only a phone, and Pi-Remote is the self-hosted relay that puts that live session in your browser so the work does not wait for your desk. Output, tool calls, and status changes sync in real time, with incremental catch up after a reconnect, and the session itself never leaves the local pi process. Send messages while pi is busy and they queue or steer, with delivery confirmed; switch the model or thinking level, compact the context, fork or clone a session, and walk the session tree, all executed locally. Several machines share one relay, and the UI lists each device, its online state, and its sessions, and can start a new session on the device you pick. Link a device by scanning a QR code, checking the 2 digit code on the confirmation page, and approving with the admin token. Desktop and mobile get separate layouts with six skins in Cursor, Claude, and Codex looks, dark and light, and token and cost usage updates in the status area. At home the relay can run serverless over the LAN, with a Cloudflare Tunnel switched on when you leave; on a server it runs under systemd or Docker Compose, and a device stays reachable only while its attach window is open. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
