What is a terminal multiplexer?

Definition

A terminal multiplexer lets a developer split work across tabs and panes while a background server owns the underlying shell sessions. Users can detach from the interface and reconnect later without stopping the processes running inside it.

For coding agents, the multiplexer can isolate parallel sessions and expose their status in one workspace. Rich integrations may add lifecycle tracking and commands, while unsupported tools continue as ordinary terminal processes.
