How this free domain name generator works
Enter a keyword or describe the business. We generate brandable .com and .net candidates, then check each one live against the registry (RDAP) before anything is shown. Taken names never reach the list. Exact-match keywords are usually gone; invented names vs keyword domains is the tradeoff. See all the features, or compare us to a Namelix alternative.
Why free generators show taken names
Most “free” namers are idea lists. They are not connected to the registry, so a name that sounds available is often already registered. This generator filters against live RDAP first. The AI Domain Hallucination Index is the measured study behind that claim.
Free domain name generator FAQs
What is Domain Search King?
An AI domain name generator that checks every suggested .com and .net live against the registry before showing it to you, so you only ever see names that are actually available to register. See all the features.
Is this domain name generator free?
Yes. Searching, AI naming, and live availability checks are free with no signup required.
How does the free generator check availability?
Every suggested .com and .net is checked live against the registry via RDAP before it is shown. Taken names never reach the results list.
How is this different from ChatGPT or other AI name generators?
Raw AI models suggest plausible-sounding names without checking the registry. Our AI Domain Hallucination Index (2,449 live RDAP checks across 10 models) found availability as low as ~8% for weaker models — i.e. up to ~92% already taken — and a July 2026 spot-check where 96/96 brandable “available” suggestions were already registered. Domain Search King verifies every name live via RDAP before it's shown, so 98.7% of our results are registrable. See the data →
What if my favorite name is already taken?
Turn off ".com only" and we surface the same name on .io, .co, .net, and .org when the .com is gone, so a good name doesn't dead-end. Or see the 7 moves that fix it for the full playbook.
