⚓ Lives in your menu bar
Every listening port under the anchor icon — kill straight from the tray without opening a window. Stays resident when you close it.
For macOS · Menu bar & window
Free your ports.
One click.
Port Mate shows every listening port on your Mac — what process,
whose it is, where it's bound — and kills it in one click.
No more lsof -i :3000 archaeology.
14-day trial · One-time $12 · No subscription · No account · Universal (Apple silicon + Intel)
Pay once. Own it forever.
Port Mate is $12, one time. Not $12 a month. Not $4 a month billed annually. Not free-with-a-Pro-tier. A tool this simple should be bought the way you buy a good pocket knife — once — and it should keep working, and keep getting updates, without renting itself back to you.
Everything a harbormaster needs
⚡ Quick-kill presets
One click to clear 3000, 5173, 8080, 5432 — or whatever ports your stack hogs. Yours to edit.
🔔 Port watching
Watch a port and get a notification the moment it frees up — or the moment something grabs it.
⌘⌥P from anywhere
A global shortcut summons the harbor ledger over whatever you're doing. Search by port, process, PID, or user.
🧭 Safe by design
SIGTERM first, SIGKILL only when you say so. Confirmation before every kill. It only manages your processes — never system ones.
🪶 8 MB, native, fast
A real Mac app — universal binary, dark-native design, instant scans. No Electron heft, no browser tab pretending to be an app.
The old way
$ lsof -i :3000
COMMAND PID USER FD TYPE ...
node 48213 you 23u IPv4 ...
$ kill -9 48213
# wait — was -9 too harsh?
# and what was on 5173 again?With Port Mate
Click Kill. Done.
Graceful SIGTERM, confirmation first,
the whole harbor visible at once.
One license, honest terms
$12
once.
That's it.
That's it.

Questions, answered
Why isn't this on the Mac App Store?
The App Store sandbox forbids apps from terminating other processes — which is Port Mate's whole job. So it's sold directly, signed and notarized by Apple the same way apps like iTerm and Rectangle are distributed.
Does it work on Intel Macs?
Yes. Port Mate ships as a universal binary — native on Apple silicon and Intel, macOS 10.15 or later.
Does it need admin rights?
No. Port Mate shows everything but only kills processes you own — which is what you want 99% of the time. System processes show with the kill button disabled, not dangerous.
What does "3 Macs" mean exactly?
One license key activates on up to three machines. Deactivate a Mac in the app anytime to free a slot — moving to a new machine is painless.
What data does it collect?
None. Port Mate runs entirely on your Mac. It touches the network for exactly two things: validating your license key and checking for updates. Your ports and processes never leave home.
Refunds?
Fourteen days, no questions. If Port Mate isn't useful, you shouldn't pay for it.
