Port & Process Explorer

Find out which process is using a port on your Mac, and stop it without opening Terminal.

What it does

• Search a port or a PID and see the process that owns it.
• Browse listening and connected TCP and UDP sockets, with their processes.
• See the processes using the most CPU and memory, and the launchd services of your user account.
• Keep favorite ports, recent ports, and your own presets.

How stopping works in this edition

The App Store edition runs inside the macOS App Sandbox, which does not allow an app to stop processes it did not start. Stop and restart buttons therefore copy the matching shell command, for example kill 12345. Paste it into Terminal and press Enter. The app never runs the command itself.

Privacy

The app collects no data. Everything it reads and stores stays on your Mac. It does not use the network. Read the full Privacy Policy.
