Domain Availability Checker

How it works

1. 1
   RDAP query

   We query rdap.org, which routes to the authoritative registry for the TLD.

2. 2
   404 = available

   When no record exists, the domain is almost certainly available to register.

3. 3
   Registrar parsed

   If registered, we extract the registrar from the RDAP entity data.

Real use cases

• — Brainstorm names for a new project, brand, or product.
• — Confirm a domain is free before pitching a name to a client.
• — Verify a typosquat or expired domain is now available.
• — Check whether to renew vs let an internal domain lapse.
