A domain name generator turns a keyword or business idea into a list of available web addresses, often with brandable made-up names and a check across extensions. Some use AI, some combine words you choose, and a few are run by registrars and hosts. Eleven options follow in no particular order.
The perfect name is easy to think of. Finding one that hasn't already been registered is the hard part, which is why most founders end up with a list of thirty ideas and none of them free.
A good generator does the checking for you. The eleven tools below are listed alphabetically and in no particular order, and every description comes from the vendor's own website, read this week. If you haven't settled on the business name yet, my free business name generator is a good first step.
Domain name generators side by side
I checked the free plan column on each tool's own website, as of Oct 2026. Yes means the site says the tool, or a plan or version of it, is free or open source. Trial only means a time-limited trial. Not stated means the pages I read named neither, even where there's a button inviting you to try it, so check the vendor's page before you sign up.

Keeping the name once you've found it
ICANN's Expired Registration Recovery Policy says registrars must notify the registered name holder at least two times before a generic top-level domain registration expires, one notice approximately one month before and one approximately one week before.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Those reminders go to the contact email on the registration. Plenty of small businesses lose a domain they've used for years because the notices went to an old address or a founder who's left. Use an email you'll still check, switch on auto-renew and put the renewal date in your calendar.
Exact match, brandable or made-up?
Exact-match names describe what you do. They're easy to understand but often taken, and they can box you in if the business grows.
Brandable names, such as two short words joined together, are easier to find available and easier to trademark.
Made-up words are the most likely to be free and the hardest to spell from hearing them once. Say any shortlist out loud to a friend before you register.
Six checks before you register a domain
- Can someone spell it after hearing it once?
- Is the same name free on the social platforms you use?
- Does it clash with an existing trademark?
- Is it short enough to fit on a business card?
- Does it read badly when the words run together?
- Will it still fit if you add products or services?
Signs it's time to rethink your domain
- People mishear it on calls. Choose an easier name.
- It's longer than four words. Look for something shorter.
- Renewal emails go nowhere. Update the contact address.
- It no longer fits the business. Plan a careful move.
Do you make domain name generators? Tool makers can ask to be considered for a featured place on this list.
My plain advice on domain name generators
Run the same three keywords through two generators, shortlist five names and register the name you like most plus the obvious misspelling the same day. Good available names don't stay available for long once you've typed them into search boxes.
Then put the name to work. My piece on using your domain name as a marketing tool shows how.
Frequently asked questions
What is a domain name generator?
It's a tool that suggests available web addresses from a keyword or idea, often checking several extensions and offering brandable variations.
Are domain name generators free?
Many are free to use for ideas, and registering the name you choose is a separate step with a registrar. Check the free plan column above for each tool.
Should I choose a .com?
A .com is still the most familiar choice for many audiences, but a country or industry extension can work well if it suits your customers.
What happens if my domain expires?
ICANN's policy requires registrars to send at least two reminders before a generic domain expires, about one month and one week before, so keep your contact email current.
Can AI suggest better domain names?
AI generators are good at brandable ideas and variations. You still need to check spelling, trademarks and how the name sounds out loud.
Should I buy similar domains too?
It's often worth registering the common misspelling or the plural, so customers who mistype still find you.
