Domain Name Checker

Check domain availability with registry-grade accuracy

Most domain search tools query cached databases or pass your search through a registrar's sales funnel. Namizy does neither: every check goes directly to the authoritative registry via RDAP — Verisign for .com and .net, Public Interest Registry for .org, Google Registry for .dev and .app. You see exactly what the registry sees, in real time, typically in 100–400 ms.

What you get with every check

For available domains: instant confirmation plus one-click registration links to Namecheap, GoDaddy or Dynadot so you can secure the name before someone else does. For registered domains: the current registrar, creation date, expiration date and full WHOIS details — useful when researching a domain you might want to buy or watch for expiry.

Can't find an available name?

The .com namespace has over 150 million registered domains, so most single dictionary words are long gone. When your first choice is taken, try the keyword domain generator to expand one idea into hundreds of prefix/suffix variations, or the AI name generator, which invents brandable names — checked for availability automatically. If you need to validate a whole shortlist at once, the bulk checker handles up to 500 domains in one run.

Why your domain choice matters

Your domain is the one piece of branding you can't easily change later. Short names are easier to remember and type; names without hyphens and numbers avoid confusion when spoken aloud; and a .com still signals credibility in most markets — studies of premium sales consistently show .com commanding the highest resale values. If you're unsure what a name is worth, run it through the free domain appraisal tool.
