Domain name search

Instant Domain Search is the fastest domain name search tool on the internet. It checks availability across 800+ extensions in under 25 milliseconds as you type. No clicking “search” and waiting for a loading screen. Unlike single-registrar tools (like GoDaddy or Namecheap’s search), IDS shows results from multiple registrars in one search, so you can register with the provider you prefer. We also aggregate results from 5+ aftermarket marketplaces like Afternic, Sedo, and Atom, surface AI-generated name suggestions, and never share your searches with registrars, meaning no one can front-run the domains you’re looking for.

When you search on a single registrar like GoDaddy, you only see their inventory. Instant Domain Search shows you options from multiple registrars (including GoDaddy, Namecheap, Hostinger, Dynadot, and others) so you can register each domain with the provider you prefer. You also get results from aftermarket marketplaces and our AI domain name generator in the same search. And because your searches never touch registrar databases, there’s zero risk of domain front-running. It’s the difference between checking one store’s shelf vs. searching every store at once.

Type any word or phrase into the search bar above. Instant Domain Search checks domain availability across every major extension in real time as you type. Green results mean the domain is available for registration, and you’ll see links to registrars where you can register it. If the exact .com is taken, we instantly show alternatives: available variations, different extensions, AI-generated suggestions, and aftermarket domains that are for sale. For bulk lookups, use our bulk domain search tool to check hundreds of domains from a list.

A domain name is the address people type into their browser to visit a website, like instantdomainsearch.com or google.com. It has two parts: the name you choose (like “instantdomainsearch”) and the extension (like “.com”). Behind the scenes, the Domain Name System (DNS) translates that human-readable name into an IP address so your browser knows which server to connect to. Read our full guide on what a domain name is and how it works.

Most standard domains cost $8–15/year for popular extensions like .com, .net, and .org. Newer extensions like .io ($25–50/yr) and .ai ($50–90/yr) cost more. Premium domains (short, memorable names that someone already owns) sell for hundreds to millions on the aftermarket. The exact price depends on the registrar and extension you choose, and you’ll see it when you register. See our guide on how much domain names cost for a detailed breakdown, or run a name through the domain appraisal to see what it would sell for.

You have several good options:

1. Try a different extension: If “example.com” is taken, check 800+ other extensions. Maybe example.io, example.co, or example.app is available.
2. Generate alternatives: Our AI domain name generator suggests creative variations based on your original idea. You can also try our business name generator for brand-focused suggestions.
3. Buy it on the aftermarket: Many taken domains are actually for sale. Our aftermarket search checks Afternic, Sedo, Atom, and other marketplaces simultaneously so you can find the owner’s asking price or make an offer.
4. Find expiring domains: Domains that aren’t renewed become available again. Browse expiring domains to find names with existing traffic, backlinks, or SEO value.
5. Contact the owner: Use a WHOIS lookup to find the registrar and, when it isn’t redacted, the owner’s contact details. Some owners are open to selling even if the domain isn’t formally listed.

For most businesses, .com is still the default. It’s what people type instinctively. But it’s not the only good option. Tech companies often use .io or .ai, nonprofits use .org, and industry-specific extensions like .app, .dev, .store, or .design can reinforce your brand. Country-code TLDs like .ca, .co.uk, or .de work well for businesses serving specific regions. The right extension depends on your audience, industry, and whether the .com is available at a reasonable price. Use our domain extensions page to browse all 800+ options and see pricing.

Yes. We’ve been providing free domain name search since 2005 and we’re ICANN-accredited. Two things set us apart on safety. First, your searches are never shared with registrars or any third party. No one can see what you searched and register it before you do (a practice called domain front-running). Second, we show results from multiple registrars and marketplaces, so you’re never locked into a single provider. We make money through small referral fees when you register through our links, and the price you pay is the same as going directly to the registrar. All searches are encrypted over HTTPS. Read our full security policy and privacy policy.

We earn small referral fees when you register a domain through one of our registrar links. The price you pay is identical to what you’d pay going to the registrar directly. We never mark up domain prices. Because we partner with 8+ registrars, we have no reason to push you toward any single provider. This model lets us keep our domain search, name generator, aftermarket search, bulk checker, and all other tools completely free. We’ve operated this way since 2005.

A domain registrar is a company accredited by ICANN to sell and manage domain name registrations. Popular registrars include GoDaddy, Namecheap, Cloudflare, and Hostinger. Each registrar sets its own pricing, renewal fees, and included features (like WHOIS privacy or DNS management). Instant Domain Search shows you registration options from multiple registrars so you can pick the provider that fits your needs. We’re also an ICANN-accredited registrar ourselves, which means we meet strict security and operational standards.

Yes. Our bulk domain search tool lets you check availability for hundreds of domain names at once. Paste a list or upload a CSV, and we’ll check each one across multiple extensions. You can filter results by availability and extension. It’s useful for brand protection (checking your name across many TLDs), portfolio management, or evaluating a list of business name ideas. Results can be exported for further analysis.

Once you find an available domain using our search tool, click the registrar link next to it to go directly to their checkout. We show you multiple registrar options so you can pick the provider you prefer. For aftermarket domains (domains someone already owns), you’ll be directed to the marketplace where it’s listed to complete the purchase or make an offer. After buying, you’ll point the domain to your website host using DNS settings. Most registrars have guides for this.
