How do I check if a domain name is available?

Type the name above and it is checked across every major extension at once. A domain shows as available when the official registry has no record of it, and taken when it is already registered. This is the authoritative source, not a guess based on whether a website loads.

Is a free domain search actually free?

Yes. Searching and seeing what is available is completely free with no account. You only pay when you choose to register a domain at a registrar, which is a separate step you control.

Can a registrar take a domain I searched for?

It is rare, but domain front-running, where a search is used to register the name before you do, has been reported over the years. This checker queries the registries directly through a small private proxy and does not log or sell your searches, so looking here does not hand your idea to anyone selling domains.

What is RDAP, and how is it different from WHOIS?

RDAP is the registries’ official lookup protocol that replaced public WHOIS in 2025. It returns a structured, authoritative answer about whether a domain is registered. We use it directly, which is why the available and taken labels here are exact rather than estimated.

Why does a domain look free but cost a lot, or look taken but show no website?

Some unregistered names are flagged premium by the registry and priced well above the standard rate, so always confirm the price at the registrar. And a domain can be registered yet parked with no live site, which still counts as taken because someone already owns it.

Are first-year domain prices the real price?

Often not. Many registrars advertise a low first-year promo that jumps at renewal. Before buying, look at the renewal price and the multi-year cost, not just the headline. We link to Namecheap because it is genuinely affordable, but the habit of checking renewal cost is worth keeping anywhere.

Domain Availability Checker

Type a name and check it across .com, .io, .co, .ai, .dev and more at once. Each result is verified live against the official registries, so available means actually unregistered, not a guess. No sign-up, and your search is never logged or sold to a registrar.

How to use it

1
Type a name

Enter a word or a full domain like acme.com. We strip it to the label and check every extension for you.
2
Read the results

Available extensions are marked clearly and sorted first, with taken ones shown struck through so you can scan in a second.
3
Register the one you want

Click an available domain to register it at Namecheap, a genuinely cheap registrar. Check the renewal price, not just the first year, before you buy.

When it comes in handy

Picking an extension

When the .com is gone, compare .io, .co, .ai and .dev for the same name side by side instead of searching them one at a time.

Checking privately

Look up a name without it being logged to a registrar that might park or upsell it. The check runs against the registry, not a sales funnel.

Before you commit

Confirm the domain is free before you print the name, build the site or pitch the idea.

Private by design, no sign-up

Names, palettes and taglines are generated right in your browser. Domain and handle checks run through a small private proxy so your browser can reach the registries, and we do not store, log or sell what you search. No account, no paywall, no limits.
