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.
The Guide
The short version: use a tool that generates creative variations of your keyword and filters them to only the names you can actually register right now. The long version involves understanding why most people get stuck — and what to do instead.
There are roughly 170 million registered .com domains. That sounds like a lot until you consider that every common English word, most two-word combos, and nearly every three-letter string registered before 2010. The domains that feel obvious — launchapp.com, buildstack.com, flowbase.com — were registered by squatters and portfolio holders within months of the commercial internet going mainstream.
But this doesn't mean good names are gone. It means the easy names are gone. The space that's still wide open: invented compound words, portmanteau names, and keyword + affix combinations that feel brandable but aren't dictionary words. Names like Notion, Figma, Stripe, and Loom were all available at the time of registration — they just weren't obvious.
The strategy is to stop trying to register common words and start generating systematic variations. A tool that checks hundreds of prefix and suffix combinations against your keyword — and filters to only the available ones — does in seconds what would take hours manually.
Not all "available" domains cost the same. Standard registrations run $9–$15/year. Premium domains are flagged by the registry or aftermarket holders as high-value and can cost anywhere from $50 to $50,000+ — even for a fresh registration with no history.
Registrars don't always make this clear. Some will show a domain as "available" in the search results and only reveal the premium price at checkout. SharpDomainSearch filters out premium-priced domains before they appear in results — every name you see costs standard registration price.
Quick check
If a domain is priced above $50/yr at checkout, it's a premium domain. You can still register it, but factor that into your budget. Standard .com registration is $9–$15/yr at any major registrar.
The practical implication: avoid very short names (3–4 characters), dictionary words, and high-search-volume keyword combinations unless you've confirmed the price. Focus on 7–12 character invented names — the sweet spot where availability is high and premium pricing is rare.
The short answer: .com if you're building a consumer-facing brand, .io if you're in developer tools and can't get the .com, .ai if your product is genuinely AI-native and your audience expects it.
The only TLD with universal consumer trust across every market, age group, and geography. People type .com automatically — a non-.com brand bleeds direct traffic to whoever owns the .com version. If you can get a strong .com, get it.
Accepted in developer and SaaS circles, but carries real trust risk outside that bubble. International users (especially in Asia) have lower familiarity with .io. Works when your audience is technical and you've confirmed the .com is legitimately unavailable or unaffordable.
Increasingly common in AI product naming. The TLD itself signals "AI product" — which is an asset if that's what you are, and noise if you're not. Pricing is higher ($50–$70/yr at most registrars). Don't use it to compensate for a weak brand name.
Popular in the 2010s as a .com alternative. Now widely seen as a fallback — the .com version is almost always taken and actively competing for type-in traffic. The association with Colombia also creates geographic confusion. Use only as a last resort.
Registrar search pages are designed to sell you something — a domain you didn't ask for, a premium upgrade, an alternative TLD when your .com is taken. Several tactics to watch for:
SharpDomainSearch routes all registrations through Dynadot, which includes free WHOIS privacy and has transparent, consistent pricing. You pay the same price on renewal as on registration.
Start with a concept, not a name
Don't try to think of a domain name — think of a concept. What does your brand do? What feeling does it evoke? What's the core verb? "Launch", "forge", "shift", "peak" — these are concepts that generate strong domain candidates. A specific name decision is easier once you have a theme.
Generate systematically
Enter your concept keyword into SharpDomainSearch. The generator combines it with 500+ proven prefixes and suffixes: get-, try-, go-, my-, -hub, -ly, -base, -co, -dev. This produces hundreds of candidates in seconds — far more than you'd generate manually, and already filtered to only available names.
Apply the radio test
Before shortlisting any name, say it out loud. Imagine telling someone your website address over the phone, without spelling it out. Can they type it correctly the first time? If you'd need to say "that's F-O-R-G-E with an E at the end", the name fails the radio test. Cut it.
Check the length and character rules
Under 12 characters is the target. No hyphens (hyphens signal spam to users and search engines). No numbers unless they're semantically meaningful (24hrs.com works; gr8names.com doesn't). If two or more of these rules are violated, move on.
Verify trademark risk
Before registering, do a quick search on the USPTO TESS database (for US brands) and Google the name. If a well-funded company with a similar name exists in your space, the name is a trademark risk regardless of whether the domain is available. The AI brandability score in SharpDomainSearch flags obvious trademark concerns, but it's not a substitute for a proper search.
Register immediately if you want it
Domain availability changes minute by minute. High-quality names generated by any automated tool get sniped by registrants running availability scrapers. If you've found a name you want, register it now — don't wait until your product is ready to launch.
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.
Yes, SharpDomainSearch is completely free. No account, no credit card, no limit on searches. You only pay the standard registration fee when you choose to register a name.
