FAQ
How accurate are the results?
Availability is inferred from authoritative DNS — if a domain has no DNS record and returns NXDOMAIN, it's almost certainly unregistered. Always confirm at a registrar before purchase, as some registered domains park silently.
Do you store the names I check?
No. Checks run from your browser straight to public DNS resolvers. We never see or log the names.
