Free Domain Availability Checker
Enter a name once and see which TLDs are still free — answers straight from each registry. No signup, no upselling, and searching never reserves the name.
Which TLDs we check
We check 50 TLDs: .com, .net, .org, .info, .biz, .dev, .app, .ai, .xyz, .tech, .cloud, .digital, .software, .network, .host, .online, .site, .store, .shop, .blog, .news, .media, .video, .studio, .design, .inc, .ltd, .company, .group, .agency, .ventures, .capital, .finance, .pro, .email, .team, .solutions, .uk, .fr, .nl, .ca, .au, .in, .br, .club, .vip, .global, .one, .link, .top.
Each one was verified individually against its registry's RDAP server to confirm the answers are trustworthy — a registered name reports as taken and an unregistered one reports as free. TLDs that don't publish a public RDAP service, including .io, .co and .me, are deliberately left out: they return “not found” even for registered domains, so including them would tell you a taken name was available. A missing TLD is better than a wrong answer.
Why check the registry directly
Most availability search boxes belong to registrars, which have an interest in what you see: suggested alternatives, urgency messaging, and — historically, at some providers — the practice of registering names people searched for. This tool reads each registry's own public record, sells nothing, and reserves nothing.
For names that are already taken, the results show the registrar and renewal date where the registry publishes them. That's useful if you're watching a domain you'd like to acquire — see what happens when a domain expires for what actually becomes of a name that lapses.
After you register one
A new domain starts a renewal clock, and a certificate clock alongside it. Both are invisible until they fail. You can check any domain you own with our free domain & SSL expiry checker, and why auto-renew failsexplains why the registrar's own setting isn't the safety net people assume.
Frequently asked questions
How does this availability checker work?
It queries each TLD's authoritative RDAP server — the registry's own public database. If the registry has no record of the domain, it's unregistered. Because the answer comes from the registry rather than a reseller, there's no upselling and no reservation of the name you searched for.
Does 'available' mean I can buy it cheaply?
Not necessarily. Available means the registry holds no registration for that domain. Some names are reserved by the registry, restricted to certain registrants, or classed as premium and sold at much higher prices. Your registrar will show the real price at checkout.
Why isn't .io, .co or .me on the list?
Those registries don't publish a public RDAP server, so there's no reliable way to check them here. Querying them through a redirector returns 'not found' even for domains that are registered — which would tell you a taken domain was free. We'd rather leave a TLD out than show you an answer that might be wrong.
What does 'Unknown' mean in the results?
It means we couldn't get a definitive answer — the registry timed out, rate-limited the request, or returned an error. We only report a domain as available when the registry explicitly says it has no record of it, so a failed lookup is never shown as free.
Do you sell domains?
No. DomainChest doesn't register or resell domains, and searching here never reserves a name. Buy from whichever registrar you prefer — then, if you like, track the renewal date here so it doesn't lapse.
Is it free?
Yes, completely free and no account needed. If you'd like to be emailed before a domain or its SSL certificate expires, you can track up to three domains on a free DomainChest account.
