Website Health Check

Run the main website, DNS and email checks on one site at once and get a short report, area by area, with links to the full results.

Website Down Checker

Check whether a website is responding right now, from our server: status, response time, redirects, IP addresses and HTTPS.

SSL Certificate Checker

Check whether a site's HTTPS certificate is valid and trusted, which names it covers, and when it expires.

HTTP Header Checker

See the HTTP status and every response header a website sends, for the final page and each redirect on the way.

Security Header Checker

Check which browser security headers a website sends (HSTS, CSP, X-Content-Type-Options, Referrer-Policy and Permissions-Policy) and what they do.

Redirect Checker

Follow a web address through every redirect, with the status code, destination and timing of each hop.

Robots.txt Checker

See a site's robots.txt rules for each crawler, spot mistakes, and test whether a page may be crawled.

Sitemap Checker

Find a site's XML sitemap, count its addresses and spot problems that make search engines ignore entries.
