🔍 whatsport

Find what's using your port and kill it easily.

Problem

"Port 3000 is already in use."

You google, then run 3 commands manually. Every. Single. Time.

Solution

npx whatsport 3000

Output:

🔍 PID 4512 → node /myapp/server.js
📁 Path: /Users/you/myapp
🧩 Command: node
✅ Suggestion: kill -9 4512
💡 Or run: npx whatsport 3000 --kill

With --kill flag:

npx whatsport 3000 --kill

🔍 PID 4512 → node /myapp/server.js
📁 Path: /Users/you/myapp
🧩 Command: node
💀 Killing process 4512...
✅ Process 4512 killed successfully!
🎉 Port 3000 is now free!

Usage

npx whatsport <port> [--kill|-k]

Examples

Check what's using a port:

npx whatsport 3000

Kill the process directly:

npx whatsport 3000 --kill
# or
npx whatsport 3000 -k

Why it's hot

Every dev hits this weekly. Now it's one command instead of three.
