Free website check

Enter a website address and we make one request to its home page: is it up, how fast does it answer, and is the SSL certificate valid. No account needed.

Only the home page is requested, once. Up to 3 checks per hour.

Human check

Loading the human check…

One request per check, made by HeedlyBot from our servers; it identifies itself and never submits forms. If you do not want to be checked, use the abuse form and we will stop.
