How it works
This tool scans YOUR localhost (127.0.0.1) directly from your browser. It detects which ports have services running - perfect for developers to quickly check their local dev environment. No data is sent to our servers.

Every open port is a potential entry point for hackers. Protect your network with a VPN.
