Domain Search

Find available domain names fast

Domain Search generates domain name ideas from any keyword and checks real-time availability across the TLDs you care about. Skip the manual hunting — get a ranked shortlist of available names in one step.

Whether you're naming a startup, launching a side project, or finding the right domain for a client, this tool surfaces creative candidates and immediately tells you which ones are actually available to register. You can also paste in a list of domains you already have in mind and verify them all at once.

What you can do

  • search_domains — generate and rank domain candidates from a keyword, checking availability across chosen TLDs
  • check_domains — verify registration status for up to 100 specific domains you already have in mind

Who it's for

Founders, marketers, and developers naming products, brands, or projects. Also useful for domain investors checking availability in bulk.

How to use it

  1. Call search_domains with your keyword or brand phrase and optionally specify TLDs like .com, .io, or .ai.
  2. Review the ranked results — available domains are surfaced first.
  3. Use check_domains to do a final availability check on your shortlist before heading to a registrar.

Getting started

Call search_domains with your brand keyword to get started. Always confirm availability directly with a registrar before purchasing.

Search Domains

Generate and rank domain candidates from a keyword or brand phrase, then check registration status for each candidate across selected TLDs.

Returns: Ranked domain candidates with availability checks, registrar metadata, and reasoning for each generated name
Check Domains

Check explicit domain names and return structured registration intelligence including source, status, registrar, and availability.

Returns: Structured registration status for each provided domain, including availability, registrar metadata, and lookup source diagnostics
Brainstorm Domains

Use an LLM to invent brandable, made-up second-level domain names from a brief, then check availability across the requested TLDs. Produces coined words (Loom, Quill, Stripe-style) instead of concatenations.

Returns: Ranked, brandable domain candidates with availability and per-name LLM rationale. Spend is one LLM call (~$0.001) plus one WHOIS lookup per candidate domain.

  • Multi-word queries now generate variants for each token as an independent seed instead of collapsing "foo bar baz" into "foobarbaz" — naming brainstorms get a full variant tree per keyword. Candidate pool expanded from 40 to 60 to fit the additional variants.
