Your domain is our domain.
Straight answers on every domain extension.
There are 1,437 live top-level domains in the IANA root. We tell you which one fits, what it really costs, and whether it’s legit — with the receipts.
Type a name, an ending like .ai, or a few words about what you are building. A green light only when a registrar confirms it; we never guess “available”.
