Browser Port Checker

About Browser Port Checker

Probe browser-reachable HTTP and HTTPS ports on a host or local device to verify basic network service access.

How to use this tool

Enter an authorized host and HTTP or HTTPS ports, then inspect the browser reachability results.

What to know

This is not a general TCP or UDP scanner. Browser-blocked ports and CORS restrictions can prevent a definitive open-or-closed result.
