Domains

See whether a name is free, who holds it, and what the registry says about it.

The tools

Free domain tools: test whether a name can be registered, read registration and expiry dates from the registry itself, and see the status codes that block a transfer.

  • Domain availability checker

    Check whether a name is registered at the registry, across endings or a whole list at once.

    Live check
  • WHOIS / RDAP lookup

    See a domain’s registrar, its dates and every status code explained, read from RDAP rather than old WHOIS.

    Live check
  • Domain name generator

    Build names from your own words and see which ones the registry has no record of yet.

    Live check
  • Domain ending explorer

    See who runs each domain ending, when it was delegated and who it suits - then check your name on it.

    Live check
  • Domain portfolio expiry checker

    Paste up to 20 domains and get the registrar, expiry date, status and days left for every one.

    Live check
  • Domain portfolio renewal calendar

    Live check

    In your browser
  • Domain naming rules checker

    Check a candidate name against the rule every ending shares, and then against that registry’s own stricter one.

    In your browser

    Follow a URL hop by hop and see the status, the target and the headers of each one.
