Domain Name Checker — Check Availability
Check if a domain name is available across .com, .net, .org, and more extensions. Instant results. Free online domain checker.
Enter domain name without extension (e.g., "example", not "example.com")
Note: This tool provides an estimate based on DNS records. A domain showing as "Likely Available" may still be registered but not configured. Always verify availability through an official domain registrar before purchasing.
Domain Name Checker — Check Availability Across TLDs
Check if your desired domain name is available across popular extensions like .com, .net, .org and country-specific TLDs.
Enter a domain name and instantly see availability across multiple extensions including .com, .net, .org, .io, .dev, .app, .co, and country-specific TLDs like .nl, .de, .uk, and .fr. The checker queries DNS records to determine registration status.
Choosing the right domain extension matters for branding and trust. The .com extension remains the most recognized and trusted globally. Tech companies often prefer .io or .dev, while country-specific TLDs like .nl or .de signal local relevance and can improve search rankings in that country.
Domain names are first-come, first-served. If your preferred .com is taken, consider alternatives: a different TLD (.io, .co, .app), adding a word (get-, try-, use-), or choosing a different brand name entirely. Avoid hyphens and numbers in domains — they reduce memorability and look less professional.
Results are based on DNS lookups and provide a strong indication of availability, but always confirm with a domain registrar before making business decisions. For more details about a registered domain, use our WHOIS Lookup to see registration dates, name servers, and registrar information.
How the Domain Checker Works

Choosing the Right Domain Name
A good domain name is short, memorable, and easy to spell. Prefer .com when possible — it's the most trusted extension. If your .com is taken, consider .io for tech projects, .co for startups, or your country code (.nl, .de, .fr) for local businesses. Avoid hyphens and numbers. Register your domain with a reputable registrar that offers DNS management, WHOIS privacy, and easy transfers.
When to Use a Domain Checker
Use this when brainstorming names for websites, businesses, or projects. Check availability across multiple TLDs before committing to a name.
Common Use Cases
- •Check domain availability before registering a brand name
- •Find available TLD alternatives when .com is taken (.io, .co, .dev, .app)

Expert Tips
- ✱Always register .com first if available — it remains the most trusted and memorable extension globally.
- ✱Check domain availability before finalizing a brand name. A great brand name with no available domains creates unnecessary friction.
- ✱Avoid hyphens and numbers in domain names — they reduce memorability and are easy to mistype when spoken aloud.
- ✱For tech products, .io, .dev, and .app are well-recognized alternatives to .com. Country-specific TLDs like .nl or .de boost local search rankings.
- ✱Always confirm availability with a registrar before making business decisions — DNS-based checks provide strong indications but are not definitive.
