Onymu

Onymu is a free brand intelligence platform for people who need a name they can actually own.

Naming something is easy until you try to claim it. You settle on a word you love, and then the real work starts: the .com went in 2003, the .io is parked at four figures, the handle is taken on three networks, and somewhere in a trademark register there's a company in a neighbouring class that will send you a letter eighteen months from now. Most name generators hand you a list of pretty words and leave that part to you.

Onymu was built the other way round — availability first.

Generate names worth checking. Describe what you're building in plain language and Onymu produces brandable candidates: invented words, compounds, short and pronounceable options that read like a company rather than a keyword string. Every suggestion is checked before you ever see it.

Check hundreds of extensions in milliseconds. Availability comes from registry zone files, refreshed daily, rather than one WHOIS lookup at a time. That means you can scan an entire TLD landscape — .com, .io, .ai, ccTLDs, the long tail — in a single search and get an answer immediately instead of watching a spinner.

Screen for trademark conflicts. Onymu checks names against trademark register data with phonetic matching, so near-misses surface too — the ones that sound like your name without being spelled like it. It's not legal advice, but it tells you which candidates are worth a lawyer's time and which to drop now.

Find the handles too. A domain without matching social handles is half a brand. Onymu checks username availability across the platforms that matter, alongside the domain results.

Know what it's worth. Every result carries an appraisal score based on length, structure, readability and extension — useful whether you're registering a name for a new project or evaluating something on the aftermarket.

Use it from inside your AI assistant. Onymu ships as an MCP server, so Claude, Cursor and other MCP-compatible tools can generate, check and appraise names directly in a conversation. Ask your assistant to name a project and it comes back with domains that are genuinely registrable — not confident hallucinations of names that sold a decade ago.
