PortMap
- macOS
Shows every active network port on your Mac with the process using it — kill, bookmark, and monitor in real time
PortMap lives in your menu bar and scans active TCP and UDP ports using lsof, displaying a scrollable list of port numbers, protocols, process names, and PIDs. Kill any process with one click, copy localhost:PORT to clipboard, and bookmark ports you care about (like 3000, 8080, 5432) so they always appear at the top with a green/red active indicator. Get alerts when a bookmarked port comes online. Configurable refresh interval from 1 to 30 seconds.
What it does
Who this is for
