Bulk domain checker

Check up to 180 domain options at once, not one search at a time.

Checking names one by one is the slowest part of naming anything: type a name into a registrar, read the result, hit back, repeat. Name Brewery checks a whole batch at once: up to 180 exact domains per call, or base names across any valid TLDs you choose.

Check your own list with your AI

Already have a list?

You don't need AI-generated names — paste your own shortlist and check it in one go. In your connected AI, just say:

Here are 40 names from my notes — check which are available, and whether any were used as a website before.

Every name comes back checked, sorted so the available ones rise to the top.

What every check returns

• Availability — available, premium, or taken.
• Price — a registrar from-price for available .coms, or the listed aftermarket price for premium names.
• History — was the name a website before? An old spam site or dead brand can drag down your Google ranking, so we link the archive.org record to check.
• Socials & trademark — handle links for X, Instagram, TikTok, YouTube, and GitHub, plus a USPTO trademark search link.
• Buy — a link to register at the registrar you choose.

Frequently asked questions

How many domains can I check at once?

Up to 180 individual availability checks per call. Send exact domains like brewhound.coffee, or send base names plus any valid TLDs or suffixes you want, such as .com, .coffee, .studio, or .co.uk. The only cap is total checks: names × TLDs, plus exact domains, must stay at or below 180.

Why is there a 180-check per-call limit?

Checks multiply quickly: names × TLDs, plus exact domains. The 180-check limit keeps each AI call fast, keeps credit usage predictable, and prevents one prompt from spending too many checks by accident. It is not a TLD allowlist; choose the extensions you want.

Do I need to install anything?

No. Connect the Name Brewery MCP server to the AI you already use — Claude, ChatGPT (Plus/Pro/Team), Cursor, or Claude Code — and ask it to check a list of names. There is also a generator on this site that checks a batch without any setup.

What do I get back for each domain?

Availability (available, premium, or taken), price (a registrar from-price for available .coms or the listed aftermarket price for premium names), archive.org history, social handle links, a USPTO trademark search link, and a buy link.

Can I paste my own list of names?

Yes. Paste a list you already have — “here are 40 names from my notes, which are available?” — and they all come back checked. You are not limited to AI-generated names.

How much does bulk checking cost?

New accounts include 20 free credits — up to 600 checks. After that it is $9 for 100 credits (up to 3,000 checks, never expire) or $19/month for 300 credits/month (up to 9,000 checks, rolls over).
