Website

Audit any site in one click.

Domain, certificate, DNS, email and speed — twenty-three live checks plus a Lighthouse run, from one field.

Runs in your browser. No signup, nothing stored.

Where the answers come from. Registration dates are read live from the registry over RDAP, the public successor to WHOIS. DNSSEC, CAA, nameservers, MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT and BIMI come from public DNS over Cloudflare and Google’s DNS-over-HTTPS resolvers. Subdomains come from Certificate Transparency logs. The certificate result is your own browser attempting a real TLS handshake, so a pass means the chain satisfied your browser’s trust store. Performance and SEO come from Google PageSpeed Insights — the only check here that involves a third party, and the only one where the URL leaves your browser. Nothing is saved.
