Free interactive tool — no sign-up

Domain Availability Checker

Type a name and see which TLDs are still free to register — .com, .io, .co, and more.

Domain Availability Checker

We'll check it across the most popular TLDs — no signup required.

Start typing above to see which domains are available.

What This Domain Availability Checker Does

Type a name, hit check, and see which domains are still open across the TLDs people actually register. No account, no credit limit, no page reload — just a straight availability read so you know whether to keep the name or go back to the drawing board.

It checks the domain's DNS records first, then confirms with a WHOIS lookup before marking anything available — the same two-step verification used by the domain checker already built into every GenName.io name generator, just as a standalone public tool.

Where This Fits Next To Our Other Tools

This tool

Free-typed name, checked live against real DNS + WHOIS data

  • Any name or keyword you type
  • Instant .com / .io / .co / etc. status
  • No AI, no account needed
Business name generator

AI-generated name ideas, with the same availability check built in

  • AI suggests the name for you
  • Availability shown per result
  • Best when you don't have a name yet

Use this checker once you already have a name in mind. If you're still brainstorming, the startup name generator or brand name generator will hand you a shortlist first, each with domain availability already checked.

Which TLDs Get Checked

The checker starts with the seven TLDs most people register against: .com, .org, .net, .io, .co, .app, and .dev. Click "Load more TLDs" to add a second batch — .ai, .tech, .me, .xyz, .info, .biz, .store, and .online — without re-checking the first set.

15 TLDs checked across both batches
2 checks per domain: DNS, then WHOIS
0 signups needed to run a check

Reading The Result

Each row settles into one of two states. Available means neither a DNS record nor a WHOIS registration was found — the domain is very likely open to register right now, though you should still confirm at your registrar of choice before paying for anything else tied to that name. Taken means someone already holds it, whether or not the site is actually live.

Do
  • Check the .com first — it's still the default people expect
  • Click a domain to copy it before you register
  • Recheck right before you buy — availability can change
  • Try a few close variants if your first pick is taken everywhere
Don't
  • Assume "available" means nobody has ever owned it
  • Skip a trademark search just because the domain is free
  • Wait too long to register a name you actually want

Common Questions

Is this domain checker actually free?

Yes. There's no signup, no credit limit, and no paid tier — it's the same availability check used across GenName.io's name generators, offered here as a standalone tool.

How accurate is the availability result?

It checks live DNS records and, when DNS comes back clear, confirms with a real WHOIS lookup — the same two-step check GenName.io's generators run on every result. It's a reliable signal, but always confirm at a registrar before assuming a domain is yours.

Does this tool register domains for me?

No — it only checks availability. Once you've found an open domain, register it through the registrar of your choice.

Why does a domain show as taken even though the site doesn't load?

A domain can be registered without anything published on it — parked pages, expired sites still under registration, or names someone is holding for later. "Taken" reflects registration status, not whether a live website exists.
