How the check works
A domain is free only when its registry says so. deepmarks asks each ending’s registry directly, the way a registrar does, and shows every ending in one list: the one you typed (or .com) first, then the popular and general ones.
- Free: the registry has no record of it. Most free endings show a price; the ones we can’t quote link to a registrar.
- Taken: someone already holds it.
- Not checked: the registry didn’t answer. We never guess “free” from DNS.
When the .com is taken
A taken .com isn’t the end of a name. When the exact match is taken, the checker suggests close alternatives on the same ending and checks them too:
- A small addition: get-, try-, use- or the- before it, or -hq, -app after it.
- The plural, when it still reads well.
- A domain hack: a name that ends in its own extension, like bit.ly.
- Another ending that suits what you do: .io or .dev for developer tools, .app for an app, .co as the usual backup.
If none of them fits, the name may be too common to own. Thestartup name generator writes names with their domains already checked.
A free domain isn’t a free name
The domain is one check. Before you commit, also search the name with your category to see who else uses it, look for the social handles you need, and search the trademark register in each market you sell in: theUSPTO in the United States, theEU’s TMview, andWIPO’s Global Brand Database for international marks. That’s a screening step, not legal advice.
Questions
Is the domain checker free?
Yes, and you don’t need an account to search. Searching the same name again the same day doesn’t count twice.
Why does an ending say “Not checked”?
Some registries don’t answer every time. When only DNS answers, we can prove a domain is taken but never that it’s free, so we say we couldn’t check it rather than guess.
Can I type a full address?
Yes. A pasted address, with or without www., reads as the domain, and a typed ending is checked first, then the others.
Does a free domain mean I can use the name?
No. A domain check is not a trademark search. Search the trademark register in each market you sell in before you commit (a screening step, not legal advice).
