Domain name generator

How to use it

1. Type your business name or a word or two about it.
2. Pick an industry for more relevant suggestions.
3. Press check: each name is looked up in its registry.
4. Open a free name at a registrar of your choice and register it there.

The check is real, and here is exactly what it asks

Pressing check sends each name to the registry that runs its extension, using RDAP — the registration data protocol that replaced WHOIS. A record coming back means the domain is registered; no record means it is not. That is the registry’s own answer about its own zone, not a guess, and it is why this tool does not simply look up whether the name resolves in DNS.

That distinction matters more than it sounds. Plenty of registered domains do not resolve — bought and parked, held by a previous owner, never pointed anywhere. A DNS check calls all of those free. They are not, and they are disproportionately the short, good names.

Why some extensions say “can’t check”

About 1,200 extensions publish an RDAP service. .io, .co, .me, .us and .de are not among them — their registries have no machine-readable lookup in IANA’s directory. So for those, nobody can be asked, and this page says so rather than guessing. It will never report an unanswerable name as free, which is the mistake that would send you to a checkout for a domain somebody else already owns.

Available is not the same as yours

A name with no registration record right now can be registered by somebody else this afternoon, and availability is confirmed only at the moment a registrar takes your money. Nor does a free domain mean a free name: check the trade mark register for your class of business before you build anything on it.

The registrar links on this page are plain searches. There is no referral code on them and Sellstamp is paid nothing if you use one — a tool that tells you whether a domain is free should not have a stake in the answer.
