How we compared them

On October 14, 2026 we typed the same 12 ideas into each tool and took the first 10 domains it showed. Tools that only take keywords got the idea's main words. We checked every domain with Namecheap the same day, and Claude Opus 5.5 and GPT-6.1 scored each one without knowing which tool made it. See every domain and score.

In our own blind test of 12 business ideas (October 2026), Nametastic's first 10 domains scored 75 of 100 on average, Namelix's 62, Instant Domain Search's 35 and Lean Domain Search's 22. How we tested

Frequently asked questions

Instant Domain Search, Namelix, Lean Domain Search, NameMesh and Nameboy are free. Nametastic's domain search checks every domain live, and you get 2 credits when you sign up.

In our test, yes: the two tools that read the whole idea scored far higher than the two keyword tools. Keyword tools still help when your domain must contain an exact word.

Some tools check later, or from old data, so their lists go stale. In our test, one tool listed a domain as free that the registrar said was taken. Nametastic asks the registrar live, during your search.

.com is still what people type first and the safest for trust, but .io, .co, .app and .ai are well known in tech. A good generator lets you weigh your first-choice name on another ending against a compromise on .com.
