What it is
Developer tool
What it does
A terminal multiplexer and tiling window manager that runs inside your terminal, keeps sessions alive through a daemon and shows the state of coding agents in each pane.
Adopt it when
You run several AI coding agents in terminal panes and want a tmux alternative that tracks which one needs you.
Watch out
It is about a year old and pre-1.0, so expect changes, and tmux remains more widely available on servers.
