In the panel
every listening port with its process and pid, marked local (127.0.0.1 or ::1 only) or open (all interfaces). Each row can open http://localhost:<port>, stop the process (SIGTERM), force quit it (SIGKILL) or copy its pid.
About
Which process is listening on which TCP port, and a way to stop it. The
command you’ll use most is Kill Port from the palette: type 3000 and
whatever holds it is asked to stop.
Processes owned by another user, like system services, can’t be stopped from here.
