SFTP Connection Tester

Verify that your SFTP server is reachable and that your credentials authenticate correctly. Tests the full SSH handshake and login.

Your credentials are used only to test your server and are never logged or stored.

About this tool

This tool performs a real SSH/SFTP handshake to your server, including key exchange and password authentication. It reports the server’s SSH software version string and the round-trip time.

Credentials are transmitted securely to our testing API and are never stored or logged. If you prefer not to test with real credentials, leave username and password blank — the tool will attempt an anonymous connection and report whether the server is reachable.

Only password authentication is supported. Key-based auth requires uploading a private key, which is outside the scope of this public tool.
