Available domains are highlighted in green. Click to copy any domain name.

Check .com first - it is still the most recognized and trusted extension for businesses.
Country-code TLDs (.de, .dk, .se) can be great for local businesses targeting a specific market.
New TLDs like .app and .dev require HTTPS, which is good for security but worth noting.
If your .com is taken, try .co or .io as popular alternatives - especially for tech startups.

We use DNS resolution first (very reliable for detecting taken domains) followed by WHOIS lookup for confirmation. Results are highly accurate but not 100% - some premium or reserved domains may show as available.

No, this tool only checks availability. To register, visit a domain registrar like Namecheap, Cloudflare, or Google Domains.

When WHOIS data is ambiguous (no clear registration info found), we mark the domain as likely available. This is usually accurate but check with a registrar to confirm.
