Site Checker Lab

Domain availability checker

Is the name registered? We ask the registry directly and never keep a list of the names you look up.

Public websites only. We keep the hostname and drop the rest.Registered or not, with the registrar and expiry date when it is taken.

How it works

We ask the registry that runs the extension whether it has a registration record for the name.

  1. 1Find the registryIANA's list says which registry runs each extension, such as .com or .org.
  2. 2Ask for the recordA record means the name is registered. No record means it is not registered right now.
  3. 3Say only what we knowAn extension without a public registry service reads “Couldn't check”, never “Available”.

Worked example: two names for a new project

example.comRegistered, with registrar and expiry date
example-new-project.comAvailable: no registration record
Next stepConfirm the price at a registrar, then register it

Premium and reserved names can have no record and still be unavailable, which is why the result says to confirm.

Frequently asked questions

Does “Available” mean I can buy it?

It means the registry has no registration record for the name. Reserved and premium names can still be impossible to buy or cost more, so confirm at a registrar before you count on it.

Do you reserve or sell the names I check?

No. We sell nothing and keep no list of the names people look up. The hostname is held in memory for about a minute for rate limiting and is never written to disk.

Why can't you check some extensions?

Some country-code registries don't publish RDAP. Then the result reads Couldn't check, never Available.

The name is taken. What now?

Look at the expiry date. If it lapses, the name usually goes through a grace period before release. Otherwise try another extension or a variation.

Can I check a name with accents or other scripts?

Yes. Type it as it is and we convert it to the form registries use, starting with xn--.
