About Domain Checker

Thinking about registering a new domain? This tool checks availability across 8 popular TLDs (.com, .net, .org, .io, .co, and more) simultaneously, so you can find the best option without searching each one separately. It also performs a full WHOIS lookup and DNS record check — useful for researching domains you're considering or monitoring ones you already own.

The standout feature is AI-powered domain name suggestions — type a keyword or concept and get creative name ideas you might not have thought of on your own. Great for startup founders, freelancers building a personal brand, and anyone hunting for that perfect domain name that's still actually available.
