Frequently Asked Questions
How does the website status checker work?▼
The tool sends an HTTP request to the URL you provide and analyzes the response. It reports the HTTP status code, response time, server headers, and whether the site appears to be up or down.
What do the different HTTP status codes mean?▼
2xx (200-299) means the site is up and working. 3xx (300-399) means a redirect. 4xx (400-499) means client errors like 404 Not Found. 5xx (500-599) means server errors indicating the site may be down.
Can I check localhost or private IPs?▼
The checker works best with public URLs. Localhost and private IP addresses may not be reachable from the browser depending on CORS policies.
Why does the tool show CORS errors for some sites?▼
Some websites block cross-origin requests for security. In those cases, the tool falls back to alternative methods and provides curl commands for manual verification.
Is my data private when using this tool?▼
Yes, the URL you enter is processed entirely in your browser. No data is sent to our servers. For sites that support it, the request goes directly from your browser to the target site.
