Enter a name without the extension, pick the TLDs you care about, and the tool will check availability against public registries — for available domains it simply lets you know you'll need to register it with a registrar of your choice.
Finding a domain name that's still available can take forever if you check one extension at a time on a registrar's site. This tool speeds that up: type in a name, pick the extensions you care about — .com, .net, .org, .shop, .store, .online, .dev, or any custom TLD — and it queries public RDAP records (with an optional WhoisJSON API key for faster lookups) to tell you which versions of that domain are still up for grabs.
A quick domain name search saves you from picking a brand name, a project name, or a business name that's already taken online. Checking availability across several extensions at once also helps you spot alternatives — if the .com is gone, the .dev or .online version might still be free — before you commit to a name.
Yes — it uses free public RDAP data by default, with no account or payment required. You can optionally add your own WhoisJSON API key for faster, higher-volume checks.
By default: .com, .net, .org, .info, .shop, .store, .online and .dev — and you can add any custom extension you'd like to check as well.
This tool only checks availability — it doesn't sell or register domains. Once you find a name you like, you'll need to register it with a domain registrar of your choice.
Some extensions aren't covered by the free RDAP bootstrap service, or a lookup can occasionally fail due to rate limits. In that case, verify the domain manually with a registrar.
