The terminal protocol for the age of agents. Your agent runs for hours on the host; check in from a laptop or a phone, on any network.

The session is its TCP connection: it dies when the network changes, and each key waits behind the download.

Survives roaming, but its own emulator can garble your screen. UDP only, no forwards, no scrollback.

The session lives on the host with Ghostty's engine. Forwards and exec share the connection, over QUIC or TCP.
