Port Scanner | The Shield IT

How it works: This tool scans ports on localhost (127.0.0.1) using WebSocket connection attempts. Due to browser security restrictions, only localhost can be scanned. Use this to audit development servers, databases, and other local services.

Note: Results may vary by browser and OS. Some ports may appear filtered if the OS resets connections before the browser detects them. This is for educational and self-auditing purposes on your own machine only.
