Domain name search checks whether a web address (for example yourbrand.com) is free to register, already owned, or marked premium. On DomainDiscovery (Domain Discovery / Domains Discovery), search is free across 1,600+ TLDs, with related tools for AI names, geo lists, bulk checks, WHOIS, and price comparison. Registration payment happens at a third-party registrar.
Domain search guide →Everything you need to know about finding and registering domains
A domain name is the human-readable address of a website (for example, domainsdiscovery.com). It maps to infrastructure on the internet so people can find and remember your brand. Use domain name search to check whether a name is still available to register.
Enter the name in the search box above. DomainDiscovery runs a live availability check across 1,600+ extensions and shows free, registered, or premium-style outcomes so you can decide quickly.

Try another TLD (.net, .ai, .io, .co), generate brandable alternatives with the AI domain generator, expand keywords, or use geo patterns for local markets. Premium or aftermarket names may still be purchasable through a registrar.
A TLD (top-level domain) is the part after the final dot — .com, .org, .ai, .io, or a country code like .uk. .com remains the default for most brands; industry TLDs can signal niche. Browse the full catalog under Domain Extensions.
Geo domains combine a city, region, or country with a niche keyword (for example, plumber + London). Local businesses and agencies use them for local SEO and multi-location campaigns. Build lists with the Geo Domain Generator.
After you find an available name, open price comparison to see regular registration pricing across registrars, then complete checkout on the registrar you choose. You only pay the registrar — DomainDiscovery search tools are free.
Yes — core search and tools are free. Saved shortlists stay in your browser unless a feature explicitly says otherwise. You pay only when you register a domain with a third-party registrar.
