Common Questions
How do I check if a domain is available?
Type the name into the domain checker above and click 'Check Now.' Namecheckly queries registry data in real time across .com, .io, .ai, .co, and 50+ other extensions, and shows you which are open and which are already registered. You only pay if you decide to register one — checking is always free and unlimited.
Is this domain checker free?
Yes, completely free. There's no signup, no account, and no cap on how many domains or name variations you can check. Search as many ideas as you need until you find one that's open.
What's the difference between this domain checker and your domain name checker?
They check the same registry data — this page is the general entry point for domain availability, while /domain-name-checker covers the same search with a slightly different framing. If you already know the exact extension you want, our TLD-specific pages (like a .com or .io checker) go deeper on that extension's pricing and rules.
Can I check multiple domain extensions at once?
Yes. Enter a name once and Namecheckly checks it across .com, .io, .ai, .co, .net, .org, and dozens of other extensions in the same search, alongside major social media handles. That way you see the full picture — not just whether .com is taken — before you commit to a name.
What should I do once I find an available domain?
Register it right away. Available domains don't stay available — anyone else searching the same idea can register it first. Namecheckly links directly to Namecheap so you can lock in the domain the moment you confirm it's free.
