Frequently Asked Questions

Find Quick Answers

What does this server checker tool do?

This tool checks if a server is online by sending HTTP requests, measures response time, returns HTTP status codes, and provides diagnostic information about server availability.

Does this tool store or log the URLs I check?

No, all checks are performed in real-time and no data is stored or logged. The tool runs entirely client-side in your browser.

Can I check servers on custom ports?

Yes, you can specify custom ports (1-65535) to check servers running on non-standard ports like 8080, 3000, or any other valid port number.

What timeout settings should I use?

The default 10-second timeout works for most servers. For slower servers or international connections, increase to 30 seconds. For local network testing, 5 seconds may be sufficient.

Why does my server show as offline when I know it's running?

This could be due to firewall restrictions, CORS policies, network issues, or the server blocking external requests. Try checking from a different network or consult your server configuration.
