Porthole lives in your menu bar and monitors listening network ports in real-time. Spot which processes have claimed your ports and dispatch them with a click.
A single-purpose instrument that does one job exceptionally well.
Every listening TCP port on your machine, surfaced at a glance. Process names, PIDs, addresses — all visible from the menu bar.
Dispatch any port-hogging process with a click. Graceful SIGTERM or the heavy hand of SIGKILL — your call, captain.
Scans every 3 seconds like clockwork. Your port status stays current without lifting a finger from the helm.
Chart your own watch list. Mark the ports that matter and see instantly which are active or lying dormant.
Ports are flagged by range — HTTP, dev servers, databases — each with its own signal color. Spot what matters at a glance.
Rides quietly in your menu bar — no dock icon, no window clutter. Click to inspect, close to stow away.
One price. Yours forever. Free updates for life.
