How the checker works
We query domain registries through our API and refresh results in real time. Most lookups complete in a few seconds depending on registry response times. We don't store anonymous searches; you can choose to save results to your account.
Sources & freshness
We use official registries and ICANN‑accredited providers via our API. Some registries cache for short intervals; we surface their latest responses.
Privacy: We don't store anonymous searches. See our privacy policy.
Common pitfalls
- Premium listings aren’t always taken domains—check the price and alternatives.
- Some registries update in short batches; try again after a minute if in doubt.
- WHOIS privacy can hide owner info; availability is what matters for registration.
Tips for choosing a domain
Keep it short, easy to spell, and relevant to your audience.
Choosing an extension
- • .com is broadly recognized for commercial sites
- • .io and .ai are common in tech
- • .org suits nonprofits and communities

Search tips

- • Avoid hyphens and tricky spelling
- • Compare a few extensions before deciding
When names are taken
- • Try a meaningful prefix or suffix
- • Consider a nearby extension you can own
- • Explore alternative brand ideas
Everything You Need to Know About Domain Checking
What exactly is a domain name?
Think of a domain name as your business address on the internet. Just like people need your street address to visit your store, customers need your domain name to find your website. It's what people type into their browser to reach you—like "google.com" or "amazon.com."
How do I pick a domain name that actually works?
The best domain names are short, memorable, and easy to spell. Avoid hyphens, numbers, or anything that makes people ask "how do you spell that?" If your business name is taken as a .com, try a relevant alternative like .io for tech companies or .co for general business.
What's the deal with all these domain extensions?
Domain extensions (TLDs) are the endings like .com, .org, .net. While .com is still king for most businesses, .io has become popular with tech startups, .ai with AI companies, and .co as a modern alternative. Choose based on your industry and what feels right for your brand.
My perfect domain is taken. Now what?
Don't panic. Try adding a relevant word (like "app," "hub," or "labs"), check different extensions, or use our AI suggestions. Sometimes the alternative ends up being better than your original idea. We've seen it happen countless times.
How accurate is your domain availability checker?
We query official domain registries in real-time, so you're getting the most current information available. Our system updates constantly throughout the day. If you see a domain as available, you can register it immediately with confidence.
Can I register domains directly through you?
We focus on being the best domain checker, not a registrar. Once you find your perfect domain, we'll connect you with trusted registration partners who can get you set up quickly and securely.
What should I do immediately after registering my domain?
First, set up domain privacy protection to keep your personal info private. Then, configure your DNS settings, set up professional email addresses, and consider registering similar variations to protect your brand. Don't forget to renew before it expires.
How does your bulk domain checking work?
Simple. Enter multiple domain names separated by commas, choose your preferred extensions, and hit search. You'll see availability for all combinations in seconds. Perfect for agencies managing multiple clients or entrepreneurs with several project ideas.
What's the difference between a domain name and web hosting?
A domain name is like your address, while web hosting is like the actual building where your website lives. You need both to have a functioning website. Think of the domain as the street address and hosting as the house itself.
How can I protect my domain privacy?
When you register a domain, your personal information becomes public in WHOIS databases. Domain privacy protection (also called WHOIS privacy) replaces your personal details with generic contact information, keeping your data private while maintaining domain functionality.
