See how many extensions each name is already taken in, for up to 50 names at once.

The number of extensions a name is registered in is one of the quickest demand signals in domaining. If dozens of people bought the same word in .net, .io, .co and .ai, the .com is valuable and the name is easy to sell. If almost nobody holds it, it is either a hidden gem or a hard sell.
Use the .com free only filter to find names where other extensions are taken but the .com is still open, then copy the free domains straight to your registrar.
It shows how many domain extensions a name is already registered in. A name taken in 40 of 50 extensions is in high demand — the .com is usually expensive or gone. A name taken in only 2 or 3 is still open almost everywhere.
We ask each extension's own registry nameservers whether the name exists in its zone, so there is no WHOIS quota and results are close to real time. Extensions that answer "yes" for every name (wildcards) are skipped and listed.
Up to 50 names per run against up to 100 extensions, and 1,000 names per day per visitor. Paste keywords or full domains — we use the part before the first dot.
No. "Free" means the name is not in the registry zone right now. Reserved, premium-blocked or just-expired names can still show as free, so always confirm at a registrar before you buy.
