Frequently Asked Questions

Find Quick Answers

What types of websites can I check with this tool?

You can check any publicly accessible website with a valid URL. The tool supports HTTP and HTTPS protocols and can analyze websites from any domain or server.

How accurate are the SSL certificate checks?

The SSL certificate verification is performed using PHP's SSL stream context, which validates the certificate chain, expiration date, and domain matching just like a web browser would.

Does this tool store or log the URLs I check?

No, all checks are performed in real-time and no URL data is stored or logged. The tool only displays results temporarily in your browser session.

Why does the response time vary between checks?

Response time depends on network conditions, server load, and geographic distance. The tool measures the actual time taken to establish a connection and receive the first byte of response.

Can I check multiple websites at once?

Currently, the tool checks one website at a time. After getting results for one URL, you can use the 'Check Another Website' button to analyze a different website.
