Website checker

Enter a website address. We'll make a real request from our server and tell you whether it's up, how fast it responded and whether its SSL certificate is valid.

Enter a domain like example.com or a full address. Free, no sign-up.

What the results mean

  • Operational

    The website answered normally and its SSL certificate (if any) is valid.

  • Warning

    The website answered, but something needs attention — such as a missing page or an SSL certificate that expires soon.

  • Down

    Visitors probably can't use the website: it didn't answer, returned a server error, or its SSL certificate is invalid.

  • Can't be checked

    The address isn't a public website we can check — for example a typo, an IP address or a private network name.

Good to know

  • Each check is a snapshot of a single moment, made from one location.
  • Some websites block automated checks (for example with bot protection); they may show as a warning even when visitors can use them.
  • We read only the response status and headers — never page content — so we cannot tell whether a page looks right.
  • Only public websites on standard web ports (80 and 443) can be checked.
