Untaken

Checks whether a domain is free by asking its official registry over RDAP or WHOIS, and will have AI propose names it then checks the same way.

Most domain checkers guess from DNS, which says a name is taken the moment anyone points a record at it. Untaken asks the registry instead: it finds the authoritative one through IANA, queries it over RDAP or WHOIS, and only falls back to DNS where a registry publishes no lookup at all.

How it works

  • Finds each extension's official registry through IANA, then queries it over RDAP, falling back to WHOIS
  • Reads the registration record itself, so an unregistered name is reported as available rather than inferred
  • Falls back to DNS only where a registry has no public lookup, and says so
  • AI can propose names from a description of what you are building, and every suggestion is checked against the same registry data
  • Cleans up whatever you paste, whether that is a bare name or a full URL
