Check domain name availability across all domain extensions at once - a fast way to see every TLD option for a single name.
When your exact .com is taken, the right extension can still get you a great domain. The All Extensions checker looks up a single name across hundreds of TLDs simultaneously - .io, .ai, .co, .net, and many more - so you can compare every option in one view.
Three steps from idea to available domain.
Type the exact name you want to check, without an extension.
NameStation checks the name across hundreds of TLDs at once.

A complete naming toolkit - not just a search box.
Check a single name across hundreds of TLDs in one search.
Instantly compare which extensions are available for your exact name.
Every extension is checked live against the domain registry.
.com remains the most trusted extension for most businesses, but .io, .ai, and .co have become established alternatives for tech and startup brands when the .com is unavailable.
Scanning every extension in one pass helps you avoid registering a name on a less common TLD only to discover the .com was actually available under a slightly different spelling.
