I built a self-hosted remote terminal that survives app kills, network switches, and phone sleep — runs on Web, iOS, Android, and HarmonyOS

Two months ago I was SSH'd into a server from my phone on a train. Switched to another app for 10 seconds, came back — tab killed, session gone.

Every mobile terminal app has the same problem: none can actually keep a connection alive. The OS kills background processes, switches networks, or puts the radio to sleep.

I flipped the model: what if the shell keeps running on a remote agent, and your phone is just the display?

Architecture

Worker — lightweight agent on any machine. Manages PTY sessions that keep running with zero connected clients.
