Domain Name Checker — Free Domain Availability Search

Before you commit to a business name, you need to know three things: is the .com available, are the social handles claimable, and is there a trademark conflict? Most domain checkers tell you the first thing. This one tells you all three simultaneously.

The domain name checker queries live RDAP registries — the same authoritative sources registrars use — so the availability data is accurate and current. Type in your business name and see results for .com, .io, .co, .app, and more within seconds, alongside Twitter, Instagram, and LinkedIn handle status.

Why domain availability matters before you launch

A name you can't get as a .com creates friction at every step of business development:

• Word-of-mouth referrals type the .com by default. If someone else owns it, they're capturing your traffic.
• Email addresses (you@yourname.com) are more professional and more memorable than you@yourname.io.
• SEO is easier to build on a brand-matching domain.
• Investors and partners instinctively look up the .com. A domain park or competitor there signals immaturity.

What to do if your .com is taken

Option 1: Modify the name. Add a prefix or suffix: "get", "try", "use", "hello", "-app", "-hq". GetMailchimp.com was Mailchimp's first domain. Tryshopify.com existed. These work while you build.

Option 2: Buy the domain. If it's parked (not actively used), the owner may sell. WHOIS lookup shows the registrant's contact. Aftermarket prices vary from $100 to hundreds of thousands — budget accordingly.

Option 3: Use an alternative TLD. .io is well-established in tech. .co is broadly recognized. .ai carries credibility for AI products. The risk is lower search volume for branded queries if users append .com instinctively.

Social handle strategy

Even if you're not active on every platform today, claim your handles now. Squatting is common — unclaimed handles get scooped up by bots and resellers. Claim @yourbrand on Instagram, Twitter, LinkedIn, and TikTok immediately after naming your business, whether or not you plan to post there.
