Free lookups

Free SuperTool

One box for every lookup. Pick a test, enter a domain, and get a plain-English result for your website, SSL certificate, email records and DNS.

Free, one-off lookups from a single location. No account needed. To have these run automatically and get an alert when something changes, see the plans.

What you can look up

Website: availability, HTTPS redirect, www and IPv6, security headers, robots.txt, sitemap and security.txt.
SSL and TLS: certificate validity and expiry, and which TLS versions the server accepts.
Email: MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, reverse DNS of your mail servers and email blacklists.
DNS and domain: nameservers, SOA sync, DNSSEC, CAA, domain blacklists and domain expiry.

How to read the result

Pass means nothing needs doing. Advice is a suggestion, not a fault. Problem means something is likely to affect visitors or email delivery. Each lookup is a one-off result from a single location, and DNS changes can take time to spread.

Want it checked for you?

The SuperTool is a snapshot. Pingee repeats these checks on a schedule and emails you only when something genuinely changes, so you do not have to remember to look. Lookups are rate limited to keep the service fair for everyone.

Stop checking by hand

Pingee runs these tests for you every day and emails you when something needs attention.
