How it works
Describe your project
Enter what your project does (subject) and who it's for (niche), then pick 1-2 naming philosophies: Tool, Authority, Minimal, or Command. The more specific your description, the better the AI can tailor names to your project's identity.
AI generates 12 candidates
AI produces 12 domain name candidates following morphology rules and TLD distribution tailored to developer projects. Each name is designed to read like a real product — not a random word mashup.
Verify availability via RDAP
Each domain is checked in real time against the registry using RDAP (RFC 7483). Available names link directly to a registrar for purchase — no middleman, no markup.

How namebox verifies domain availability
namebox.dev queries RDAP (Registration Data Access Protocol, RFC 7483) in real time against the registry. RDAP is the modern replacement for WHOIS and provides structured JSON responses directly from the authoritative registry operator. No DNS approximation is used; results reflect current registration status at query time.
