When to use this
- Brand availability sweep: paste your shortlist of
brand.com / brand.io / brand.app / brand.coand see which extensions are open in one shot. - Acquisition shortlists: check a portfolio of domains for expiry dates before reaching out to the registrant.
- Cleanup before purchase: drop in a list scraped from a brainstorming session and instantly drop the ones already taken.
How the check works
Each domain is queried live against the public WHOIS network through the free whois.ls API. Domains with no WHOIS record are marked as Available; domains that return a creation date or registrar are Taken; lookups that error out or hit unsupported TLDs are marked Unknown so you can investigate manually.
WHOIS availability is highly accurate but not registrar-grade — for final purchase decisions confirm at your registrar of choice. We never store your queries.
