About DomainSearch.co

DomainSearch.co is a free tool for checking domain name availability and running WHOIS lookups. It was built for founders, brand teams, and developers who need a fast way to check a name across many TLDs at once, without signing up for anything.

What you can do here

• Check availability for a name across 27+ TLDs in one search.
• Filter results to popular TLDs or pick exactly which ones to check.
• Run a free WHOIS lookup to see registrar, key dates, nameservers, and DNSSEC status.
• Jump straight to a registrar to buy or enquire about an available or premium name.

What we're not

DomainSearch.co is an independent search tool, not a domain registrar or registry. We don't process domain purchases or registrations ourselves — when you're ready to buy, we link you to a registrar to complete the transaction there.
