Brand name tester · one decision record

Test a brand name without turning uncertainty green.

Check one candidate across quality dimensions, selected domain endings, exact developer namespaces, namesake research, and hard blockers. Every external claim keeps its source, time, state, and confidence.

Unknown never means available

One framework for 1 or 200 names

Sources and check times included

Live checks run only after you submit.

Explainable dimensions

See spelling, pronunciation, distinctiveness, category fit, channel fit, and brand-width considerations separately.

Calibrated domain evidence

A domain only counts as likely unregistered after the registry passes a canary test: a control lookup of a domain we know is registered, proving its answers can be trusted.

Honest unresolved states

Timeouts, rate limits, unsupported sources, conflicts, and missing evidence remain unknown or manual.

Practical answers

Before you name, check, or ship

Availability is time-sensitive evidence. A final choice still needs current registrar verification, spoken testing, cultural review where relevant, and appropriate legal clearance.

What score means a brand name is safe?

No score establishes legal safety. Scores help compare usability; hard collision signals and incomplete legal work stay outside the average.

Why does a domain sometimes say likely unregistered instead of available?

Registry absence is evidence about a lookup at a point in time, not a guarantee that a registrar can sell the domain at an acceptable price.

Can I compare more than one name?

Yes. Use the creator workflow for a broad field and shortlist up to three finalists for deeper comparison and research.
