Check a site before you change it

Website, HTTPS, redirects, DNS and email settings in one check. Free, and nothing to install.

Moving DNS to a new provider? Compare your zone files first.

  1. 01Website & HTTPSLoads, valid certificate, clean redirects, security headers.
  2. 02DNSNameservers, where the domain points, obvious inconsistencies.
  3. 03EmailMX, SPF and DMARC, so mail keeps arriving after the change.
