What data it sees

Do you need an account

No: the server works without sign-in

Bulk domain checks for AI chats — availability, prices, history, social handles, and buy links.

Name Brewery gives your AI a domain-lookup tool right in the conversation. Your AI brainstorms the names; check_domains reports whether each one is already registered, plus aftermarket listings with prices, archive.org history, registrar pricing, social handle links, and a buy link for every available name — up to 50 names across 6 TLDs per call. It reports lookups it never generates or judges names, so brainstorming stays in the chat.

Tools

  • check_domains — availability, prices, history, social/trademark links, buy links (1 credit per 30 checks)
  • check_credits — remaining credit balance (free)
  • favorite_domains — save names to your Name Brewery account (free)

Try

  • "Brainstorm 15 names for my kite shop, then check which are available."
  • "Here are 40 names from my notes — which are available, and which have a past on archive.org?"
  • "Save brewhound.com and maltforge.com to my favorites."

Access

Sign in with Google, GitHub, or an emailed code on first connect. New accounts get 20 free credits (up to 600 checks).
