Available Domain Name Search — Free
Search any keyword and instantly see which domain names are available to register. Every generated name is checked against the live .com registry — no cached data, no stale results, no taken names in your list.
How it works
We query a live registrar API for each domain — real-time registry data, not DNS, not a cached database.
Registered-but-undelegated domains (no website, no DNS) are still caught. Most tools miss these — we don't.
We focus exclusively on .com. No TLD noise, no .xyz fallbacks. If it's shown, it's a real, available .com.
The accuracy gap
There are three ways to check domain availability — DNS lookup, WHOIS query, and registrar API. Most free tools use DNS. Only the registrar API is reliable.
A DNS lookup checks whether the domain resolves to an IP address. But thousands of registered domains have no DNS records at all — they're held by registrants who never built a website. DNS says "available". The registrar says "taken". SharpDomainSearch uses the registrar.
WHOIS can catch registered domains without DNS, but registry WHOIS servers are rate-limited, inconsistent across registrars, and often delayed by 24–48 hours after a new registration. Not suitable for real-time availability checking at scale.
A live registrar API checks directly against the registry's authoritative data — the same source a registrar queries when you go to purchase. If the API says available, it's available. No false positives, no DNS gaps, no stale cache.
SharpDomainSearch checks each generated name via a live registrar API. If the domain has no active registration record, it's shown as available. Results are real-time — the same data a registrar sees when you go to purchase.
Yes. We check availability via a live registrar API — results reflect the actual registry state, not a cached snapshot. If a domain shows as available, it's available right now.
A domain is available if it has no active registration record in the .com registry. Even domains with no website can be taken — our live registrar API catches these, not just DNS checks.
