.dev domain name checker

.dev is a generic TLD run by Google Registry for developers and the things they build: tools, docs, portfolios and side projects. It's open to anyone.

Type the full domain, like yourname.dev. You’ll also see the same name across 100+ other TLDs.

How we check
Registry RDAP. ICANN requires generic TLD registries to publish registration data, so answers come from the source.

Worth knowing

  • The whole TLD is on the HSTS preload list, so browsers only connect over HTTPS. Most hosts issue certificates automatically, but plain-HTTP setups won't load.
  • As a generic TLD, it publishes registration data over RDAP, so AvailableWhois checks the registry directly.
  • Good for product docs and APIs (docs.yourname.dev) even if your main site lives elsewhere.
