- Checks the requested extension plus common alternatives such as .com, .net, .org, .app, and .io.
- Uses RDAP registration responses and clearly labels uncertain or unsupported results.
Common uses
- Check a brand or project name before starting a website.

- Quickly confirm whether a domain is already registered.
Frequently asked questions
Does “available” guarantee that I can buy the domain?
No. It means the RDAP service did not find a registration at the time of the check. A registrar may classify the name as premium or reserved, and another person can register it first.
Why might a result be uncertain?
Some registries limit or temporarily disable RDAP queries, and not every country-code extension publishes a compatible RDAP service.
