Domain Availability Checker

Try for free

Check which domain names are still free to register. Combine names with endings such as .com, .io and .ai, or paste full domains. Asks the registries' official RDAP and WHOIS services and double-checks with DNS; for taken domains you get the registrar and expiry date.
