Domain Name Search

What is this domain name search tool?

This domain name search checks whether a name is available across many extensions at once. Enter a keyword or brand and it queries popular TLDs — including modern ones like .io, .ai, .dev, .app, .xyz, .online, .store, and .tech — using RDAP for authoritative available-or-taken status.

Available names show a green pill with a Register button; taken names show a red pill. It doubles as a bulk domain name search and a way to search who owns a domain name.

How to search a domain name

1. Type your keyword, brand, or full domain into the box above.
2. Pick a TLD (or let the tool check the popular set for you).
3. Read the status pills — green means available to register, red means taken.
4. Click Register on any available name, or review the keyword-based suggestions below your results.

Checking availability across TLDs

Instead of checking one extension at a time, this tool runs a single search across the classic TLDs (.com, .net, .org, .co) and the newer gTLDs in one pass. Because it uses RDAP — the modern replacement for WHOIS — the available-or-taken result is authoritative, not a guess based on whether a page loads. That makes it a practical bulk domain name search when you are naming a startup or product and want every good option on one screen.

Search who owns a domain name

When a name comes back as taken, it is already registered by someone. To search who owns a domain name — a domain name search by owner — run the taken domain through our hosting checker, which pulls the registrar and registration details via RDAP. That tells you who registered it and when it expires, which is the starting point for making an offer on a name you want.

Common use cases

• Naming a new business, product, or app and grabbing the matching domain.
• Comparing a brand across .com, .io, .ai, and other extensions in one search.
• Running a bulk domain name search to shortlist available names fast.
• Checking whether a name is free before you print it on anything.

Frequently asked questions

How do I do a domain name search?

Enter your keyword or brand above and run the search. The tool checks availability across popular TLDs and shows a green pill for names you can register and a red pill for names that are taken.

Can I run a bulk domain name search?

Yes. A single search checks your name across many extensions at once — classic TLDs plus modern gTLDs like .io, .ai, .dev, and .app — so you see every available option together instead of checking one at a time.

How do I search who owns a domain name?

If a name is taken, run it through our hosting checker to see the registrar and registration dates via RDAP. That is the fastest way to do a domain name search by owner and find out who holds the name.

Are the results accurate?

Yes. Availability is confirmed with RDAP, the authoritative registry protocol, so a green "available" pill reflects the registry's own status rather than a page-load guess.
