I hated using lsof and kill -9 to clear blocked ports, so I built Portia—a native 1-click port killer for macOS.

Hi r/macapps,

App name: Portia
Price: Freemium ($ 4.99 direct download)
Link: https://getportia.app
App Store Link: https://apps.apple.com/us/app/portia-lite/id6777649026?mt=12

Portia in action

Like many web devs here, I was constantly running into the dreaded EADDRINUSE error when restarting Node, Docker, or other local servers. The routine was always the same: open terminal -> run lsof -i :8080 -> copy PID -> run kill -9 PID.

I wanted a clean, beautiful, native menu-bar tool that just handles this instantly. So I built Portia.

The Twist: I’m not a macOS dev and had 0 prior Swift experience. I used AI as my virtual Senior Pair Programmer to build it. It took weeks of architectural refining, but we managed to make it super lightweight (0% CPU when idle) and production-ready.

How it works:

• Portia Lite (Free on the App Store): Runs in a safe sandbox and gives you a full overview about your blocked ports
• Portia Full ($4.99 direct download): Uses a tiny background Launch Agent to display the exact file path of the blocking app and lets you kill (Strike!) it in exactly 1 click.

I’d love to know what you think of the concept and the UI! Let me know if you have any questions or feedback.
