OpenFrequently asked questions
How does the domain name generator work?
Enter a keyword and the generator combines it with common prefixes (get, try, my), suffixes (app, hq, labs), and extensions (.com, .io, .ai, .app, and more), then checks each candidate's live availability via RDAP. Available names are surfaced first.
Is the availability real-time?
Yes. Each generated name is checked against live RDAP data at the moment you run it, so 'available' reflects current registry status. Always confirm at a registrar before relying on it, since availability changes constantly.
Is it free?
Completely. No login, no credit card. Generate as many times as you like.
What makes a good domain name?
Short, clean, pronounceable, and ideally on a strong extension like .com or .io. Avoid hyphens and numbers where you can. Our portfolio value estimator scores names on exactly these signals.
Where do I keep my shortlist?
