// DOMAIN AVAILABILITY CHECKER · ABOUT THIS TOOL

About the Domain Availability Checker

The Domain Availability Checker probes a name with live DNS queries and a WHOIS lookup, then gives a plain verdict: Likely registered, Likely available, or inconclusive, with the evidence shown.

It is ideal for brainstorming brand and startup names, checking alternatives to a taken domain, and screening shortlists before you open a registrar.

Where it helps most

The naming workflow, minus the checkout surprises.

Brand brainstorming

Founders test dozens of name variants in minutes and shortlist only the registrable ones for the final decision.

Client registrations

Agencies check availability across the TLD set a client cares about in one pass, without repeated registrar searches.

Domain investing

Investors run repeat checks to catch the moment a wanted domain drops back into the pool.

Defensive variants

Check the plural, the hyphenated version and common misspellings alongside your first choice, since defensive registrations are cheaper than disputes.

Checking well

Getting honest results.

Multiple TLDs at once

Enter one name and check .com, .net, .org, country codes and newer extensions side by side.

Available versus taken

Results separate free names from registered ones in a single view, no repeated registrar searches.

Natural next step

When a name is taken, the WHOIS lookup shows whether it might be acquirable and when it expires.

Domain Availability Checker: built for trust

Live registry data with no account needed. Final registration always happens at a registrar, where pricing and premium tiers apply.
