Check whether a URL or hostname is reachable via HTTP/HTTPS. Tests response time, status code, and redirects.
🌐 Uses fetch() , browser-basedThis tool uses the browser's fetch() API to attempt an HTTP HEAD request to the target URL and measures the response time. It can detect reachable/unreachable status and HTTP response codes. Note: CORS policies on some servers may block the request even when the site is up , in that case the tool will show a CORS warning rather than a false failure. For a definitive check, use a server-side tool.
