Frequently Asked Questions

Are these tools free to use?

Yes, completely free. No signup, no credit card, no limits for normal usage.

Do you store the domains I look up?

We log lookups anonymously for improving the service. We do not tie lookups to your identity unless you voluntarily provide your email. See our data usage policy for full details.

How accurate is the data?

Whois data comes from RDAP (the official IANA-standard protocol). DNS data is fetched live from Google Public DNS. Technology detection analyses live website HTML and headers.

What other tools are you building?

We're adding more tools including SSL Certificate Checker, HTTP Headers Inspector, Sitemap Validator, and Redirect Chain Checker. Bookmark this page to stay updated.
