Everything you need, nothing you don't

A single-purpose instrument that does one job exceptionally well.

Port Monitoring

Every listening TCP port on your machine, surfaced at a glance. Process names, PIDs, addresses — all visible from the menu bar.

Process Management

Dispatch any port-hogging process with a click. Graceful SIGTERM or the heavy hand of SIGKILL — your call, captain.

Auto-Refresh

Scans every 3 seconds like clockwork. Your port status stays current without lifting a finger from the helm.

Watched Ports

Chart your own watch list. Mark the ports that matter and see instantly which are active or lying dormant.

Color-Coded Display

Ports are flagged by range — HTTP, dev servers, databases — each with its own signal color. Spot what matters at a glance.

Menu Bar Native

Rides quietly in your menu bar — no dock icon, no window clutter. Click to inspect, close to stow away.
