Open Port Scanner Tool

Open Port Scanner helps you check whether common network ports are open or closed on a website or server. This tool is useful for server administrators, developers, cybersecurity learners, and SEO professionals to analyze basic server accessibility.

How This Port Scanner Works

This tool performs browser-safe port checks using HTTP requests. Due to browser security policies, it checks accessibility rather than deep TCP scanning. Results may vary depending on firewall and server configuration.

No data is stored, and scans are performed directly from your browser.
