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.
Open Ports = Security Risk
An open port only matters if the service behind it is exposed and unpatched. Close what you do not use at the router; a VPN does not close ports on your network.
