What Is a Domain Availability Checker?
A domain availability checker is an online tool that instantly verifies whether a domain name is available for registration. When you search for a domain like yourbrand.com, the tool queries registrar databases and DNS records to determine if the name is already taken or still open for purchase. Unlike simple single-TLD checks on registrar websites, a bulk domain checker tests your desired name across dozens or even hundreds of top-level domains (TLDs) simultaneously.
Our free domain availability checker goes beyond basic availability lookups. It checks 100+ TLDs in a single search, displays real-time registration and renewal pricing, detects premium domain names with their exact pricing, and organizes results by category — making it easy to find the perfect extension for your project. Whether you're launching a startup, building a personal brand, or registering domains for clients, this tool gives you the complete picture in seconds.

TLD Guide — Choosing the Right Domain Extension

Popular TLDs
.com — The most recognized and trusted extension worldwide. First choice for businesses.
.net — Originally for network providers, now a strong .com alternative.
.org — Trusted by nonprofits, communities, and open-source projects.
.io — The go-to TLD for tech startups and SaaS companies.
Tech TLDs
.dev — Google-operated, requires HTTPS. Perfect for developers.
.app — Ideal for mobile and web applications.
.ai — Hugely popular for artificial intelligence and tech companies.
.tech — Broad technology branding.
Business TLDs
.co — Short, memorable alternative to .com for companies.
.agency — Clear positioning for digital and creative agencies.

.studio — Creative studios and art-focused brands.
.media — Media companies, content creators, publishers.

Domain Name Best Practices
Choosing the right domain name is a strategic decision that affects your brand recognition, SEO performance, and marketing efforts for years to come. Follow these best practices to make the best choice:
Keep It Short
Aim for 6-14 characters. Short domains are easier to remember, type, and share. Every extra character increases the chance of typos.
Make It Brandable
Choose a name that can become a brand, not just a keyword. "Spotify" beats "best-music-streaming.com" every time.
Easy to Pronounce
If you can't say it in conversation, it's too complicated. A domain should pass the "radio test" — someone hearing it can type it correctly.
Avoid Hyphens & Numbers
Hyphens and numbers cause confusion when spoken. People will forget the hyphen or type the number as a word (and vice versa).
Check Trademarks
Before registering, search trademark databases (USPTO, EUIPO) to avoid legal issues. Even if a domain is available, the name might be trademarked.
Think Long-Term
Your domain is a long-term investment. Choose a name that won't feel dated in 5 years and can grow with your business beyond its initial niche.
Why Use an AI Domain Name Generator?
Traditional domain name generators rely on simple string manipulation — appending prefixes, suffixes, or combining keywords mechanically. The results feel robotic and uninspired. An AI-powered domain name generator fundamentally changes the game by understanding context, language nuance, and branding principles.
Context-aware suggestions — The AI understands your business description and generates names that are semantically relevant, not just keyword-stuffed combinations.
Creative naming strategies — The AI uses multiple strategies including portmanteau (Spotify = spot + identify), invented words (Zillow, Hulu), and creative spelling to generate truly unique names.
Objective brand scoring — Instead of guessing which name "feels right," get data-driven scores across memorability, brandability, pronounceability, uniqueness, and relevance.
Instant availability checking — Each AI suggestion is automatically checked for availability across top TLDs, so you know immediately which names you can actually register.
Style customization — Choose between brandable (invented words), short (3-6 characters), keyword-rich (industry terms), or creative (playful combinations) to match your branding strategy.
Domain Pricing Explained
Domain pricing varies significantly depending on the TLD, registrar, and whether the domain is classified as "premium." Understanding the pricing structure helps you budget accurately and avoid surprises at renewal time.
Registration Price
The first-year cost to register a domain. Prices range from $0.99 for promotional TLDs to $15-40 for standard extensions like .com ($8-12), .io ($25-35), or .ai ($30-50). This is often discounted as a promotional rate.
Renewal Price
The annual cost to keep your domain after the first year. Renewal prices are typically higher than the initial registration. For example, a .com might cost $8.88 to register but $12.98 to renew. Always check the renewal price before registering.
Premium Domains
Premium domains are high-value names (short words, exact-match keywords, dictionary terms) that registries price higher than standard registrations. A premium .com might cost $500-$10,000+ to register, with proportionally higher renewal fees. Our tool clearly marks premium domains and shows their exact pricing so there are no surprises.

How does the AI domain name generator work?
Our AI domain name generator uses Claude AI to analyze your business description, industry, and style preference. It generates unique domain name suggestions using strategies like portmanteau, invented words, keyword combinations, and creative spelling. Each suggestion comes with a brand score (1-10) broken down into memorability, brandability, pronounceability, uniqueness, and relevance — then automatically checks availability across top TLDs.
How many TLDs can I check at once?

Are the domain prices accurate?
Yes, domain prices are fetched in real-time from registrar APIs and updated every 24 hours. You see the actual registration price (first year) and renewal price for each TLD. Premium domain names show their exact premium pricing, which can differ significantly from standard registration prices.
What is a premium domain?
A premium domain is a previously registered or registry-reserved domain name that is available at a higher price than the standard registration fee. Premium domains typically consist of short, common words, exact-match keywords, or highly brandable names. Premium pricing is set by the domain registry or aftermarket seller, and renewal prices may also be higher than standard rates.
What makes a good domain name?
A good domain name is short (ideally under 15 characters), easy to spell and pronounce, memorable, and relevant to your brand or business. Avoid hyphens, numbers, and double letters that cause confusion. Our AI generator scores each suggestion across five criteria: memorability, brandability, pronounceability, uniqueness, and relevance to help you choose the best option.
Which TLD should I choose for my website?
.com is the most recognized and trusted TLD, ideal for businesses targeting a global audience. .net and .org are strong alternatives. Industry-specific TLDs like .io and .dev work well for tech companies, .store and .shop for e-commerce, and .agency or .consulting for service businesses. Country-code TLDs (.us, .uk, .de) are best for businesses targeting specific regions.
Can I register a domain directly from this tool?
Yes! Each available domain has a 'Register' button that takes you directly to a trusted registrar where you can complete the purchase. Pricing shown in our tool reflects the actual registration cost you will pay, including any ICANN fees.
What is brand scoring for domain names?
Brand scoring is an AI-powered analysis that rates domain names on a scale of 1 to 10 across five dimensions: memorability (how easy it is to remember), brandability (how well it works as a brand), pronounceability (how easy it is to say), uniqueness (how distinctive it is), and relevance (how well it fits your business). The overall brand score is a weighted average of these five metrics.

Yes, our domain availability checker is completely free to use. You can check unlimited domains across 100+ TLDs, view real-time pricing, and use the AI domain name generator — all without creating an account or paying anything. The tool is supported by affiliate partnerships with domain registrars.
