Domains
Start with the .com.
We ask the registries directly, then show you what else is free under the same name.
Endings we check
- .comThe one you can't get later. Always checked first.
- .coShort, credible, and mistyped as .com more than people admit.
- .netReads as infrastructure. Fine for tools, odd for consumer brands.
- .ioTechnical audiences read it as normal. Everyone else reads it as a typo.
- .aiSays something about your product. Make sure it's something you mean.
- .appHTTPS-only by design, which is a small real security win.
- .devAlso HTTPS-only. Unambiguously for developer-facing things.
- .orgSignals non-profit whether or not you are one.
Where the answer comes from
RDAP — the registries’ own lookup service, and the successor to WHOIS. It is open, free and authoritative: if a registry says a domain isn’t registered, it isn’t registered.
A few registries don’t run one. There we fall back to DNS, which can prove a domain is taken but can never prove it’s free — so a domain with no DNS records comes back Unknown, not Available. It’s a less satisfying answer and a more honest one.
Available doesn’t mean cheap
Some free domains are premium-priced by the registry, and the price only appears at the registrar. We report registration status, not price.
Check the handles at the same time
A domain with no matching handles is half a decision. Every domain check here runs the social platforms alongside it, because that’s the question you actually have.
