👻 PortGhost
See what haunts your ports. Exorcise the demons.
PortGhost is a Windows desktop app that reveals which processes are haunting your network ports — perfect for developers tired of "Port 3000 is already in use" errors.
🎯 The Problem
You run npm run dev and see:
Error: listen EADDRINUSE: address already in use :::3000
Some ghost from yesterday's coding session is still haunting that port.
👻 The Solution
PortGhost shines a light on port hauntings:
Enter the port (e.g., 3000)
See the ghost — Process name, PID, path, start time
Bust the ghost — One-click process termination
