About
Onymu is a free domain name generator and availability search. Type one word and it answers in milliseconds with every extension still free to register 1,400 of them, not the six a registrar puts in front of you.
It is the whole naming check in one box:
Domain search — one name against 1,400 TLDs, or a comma-separated list of names side by side.
Domain name generator — brandable variations, filtered down to the ones still available.
Social handle check — the same name on 12 social platforms, plus App Store and Google Play name matches.
WHOIS and DNS — who holds a taken domain, when it expires, and what its records say.
Domain appraisal — an estimated resale value for any domain, with a printable certificate.
Brand preview — your name drawn into 28 mock-ups: a Google result, an app store listing, an inbox, Instagram, a business card.
MCP server — 11 tools, so Claude and other AI assistants can run the same searches for you.
Registry data refreshes daily. No account is needed to search or generate, nothing is sold on the site, and every extension links out to a registrar so you compare prices yourself.
Free, and staying free.
