Domain Availability Checker
Check if a domain name is available or taken across multiple TLDs (extensions) in one search. A good domain name does two jobs at once: it's easy to remember, and it's actually available.
Use the NameWisp checker above to search your desired name across multiple extensions in one pass. Instead of repeating the same query on different websites, you can quickly compare your best options and move on to the more important part: building the thing.
Why check a name across multiple TLDs?
Most people start with a .com and discover reality: it's often taken. That's why domain search tools emphasize checking availability first and, if needed, exploring other extensions when the first choice isn't available.
Checking multiple TLDs at once helps you answer three practical questions fast:
- Is the exact name available anywhere credible?
- If not, which extension still looks trustworthy for my audience?
- Which option is easiest to say, type, and remember?
How to use NameWisp to check domain availability
Most registrars and domain search tools follow the same basic flow: enter a name, get an immediate "available or owned" result, then choose what to do next.
With NameWisp, the simplest workflow is:
Enter your domain name (without an extension)
Type the base name you want (for example, namewisp rather than namewisp.com).
Check across multiple extensions
Run one search and review availability across the TLDs you care about.
Decide based on the result
If it's available, you've got a clear path forward. If it's taken, you can immediately evaluate alternatives.
Understanding the results: Available vs Taken
NameWisp keeps the output simple:
One important reality: domain availability can change quickly. If you find a name you really want, treat it like a limited resource, because it is.
Choosing the right domain extension
A TLD (top-level domain) is the last part of a domain name, like .com. There are also country-code TLDs (like .uk) and generic TLDs (like .com).
When choosing an extension, keep it simple and user-facing:
Memorability
Pick something people won't mishear or mistype.
Trust
If your audience expects a "standard" extension, prioritize that. Many domain tools still frame .com as the default starting point, with other options as alternatives when .com is taken.
Fit
Some extensions feel "native" to certain products or geographies (for example, a country TLD can be a strong signal for a country-specific business). Just make sure it matches your actual target market.
If your domain is taken: what to do next
If your first-choice domain is taken, you typically have three clean options:
- 1. Check the same name on a few alternative extensions (still readable, still brandable).
- 2. Adjust the name slightly (one meaningful word, not random letters).
- 3. Choose a different name if every reasonable option looks forced.
Many mainstream domain search pages explicitly guide users to explore other extensions or alternatives when a domain is unavailable because that's the normal outcome of domain searching in 2025.
FAQ
What is a domain extension (TLD)?
A domain extension is the last part of a domain name (like .com). TLDs include generic TLDs (like .com) and country-code TLDs (like .uk).
How do I check if a domain is taken?
Use a domain availability checker: enter the name and you'll see whether it's available or already owned. This is exactly how major registrars describe the process.
Can I check a name across multiple extensions at once?
Yes. Many domain search tools position multi-extension checking as a core benefit, letting you compare availability across a wide range of TLDs quickly.
