PortKill9
Kill ports instantly on macOS. No terminal, no lsof,
PortKill9 is a native macOS app that kills any process occupying a port — one click, one second, done. No more typing `lsof -i :3000`, finding PID, running `kill -9`. Just enter your port number and hit Kill. Built for developers who restart local servers daily and constantly fight "port already in use" errors. Especially handy for vibe coding workflows where you're spinning up and tearing down dev environments all day long. Native macOS experience. Zero dependencies. Just works.
Hey hunters! 👋
I built PortKill9 because I was tired of the same ritual every single day:
1. Run my dev server → "Error: port 3000 already in use"
2. Open Terminal
3. Type `lsof -i :3000`
4. Find the PID
5. `kill -9 `
6. Realize it didn't work, repeat steps 3-5
As a vibe coding enthusiast using tools like Trae.ai and WorkBuddy daily, I restart servers dozens of times. This tiny friction adds up to hours per week.
So I made PortKill9 — a native macOS app that does exactly one thing: kill ports instantly. One click, one second, done.
Would love your feedback! What other developer pain points should I tackle next? 🚀
