Business Name Availability

Check domain availability and social handle availability for your business name — instantly, across all the extensions that matter.

How it works

Checks domain availability for .com, .io, .co, and .ai TLDs using real DNS lookups — not a WHOIS scraper. If a domain resolves (has A or NS records), it's taken. Then checks Twitter/X, GitHub, and LinkedIn handle availability via their public APIs. Results in under 10 seconds, no account required.

  • ✓Twitter/X, GitHub, and LinkedIn handle availability
  • ✓Color-coded: green = available, red = taken
  • ✓Direct copy link for available domains
  • ✓Real DNS check — not a cached database
