FREE ONLINE FTP PORT CHECKER

FTP Port Checker

Check common FTP, FTPS, SFTP, HTTP and HTTPS ports for any public hostname. This free FTP Port Checker verifies whether important file transfer ports are reachable and attempts to detect the actual service responding on each port.

Instead of only reporting whether a TCP port is open, the tool performs lightweight protocol checks to identify FTP banners, SSH banners and HTTP responses. This makes it easier to spot firewall issues, wrong service bindings and misconfigured ports.

What does this FTP port checker test?

The tool tests common ports used for FTP, SFTP, FTPS and web-based file transfer workflows. It checks whether each port is reachable and whether the expected protocol appears to be running behind it.

This is useful when troubleshooting connection failures, validating firewall rules, checking NAT or reverse proxy configuration and confirming that FTP, SFTP or FTPS services are exposed correctly.

Who is this FTP port checker for?

This tool is designed for system administrators, DevOps engineers, developers, hosting providers and IT support teams responsible for FTP, FTPS, SFTP and secure file transfer services.

It is especially useful when verifying a new server deployment, debugging blocked ports, checking external accessibility or confirming that the correct service is responding on the expected port.
