How do I check if a domain name is available?

Ask the registry: this tool checks each idea on its TLD registry's RDAP server and in DNS. No record and no nameservers means likely available. Your registrar confirms it, along with the price, before you buy.

Is this domain name generator free?

Yes, it's a free tool with no account, card or payment. Each run checks up to 60 ideas, and one connection can check 100 domains a minute across the domain availability tools.

Why are .io and .co names shown as unknown?

Their registries don't publish RDAP in IANA's directory, so there's no registry record to read. A name with nameservers in DNS is shown as registered; otherwise it's unknown, never available. Check those at a registrar.

Does the generator use AI?

No. Ideas come from fixed prefix and suffix lists, keyword joins and short blends, so the same keywords always produce the same names. Nothing is sent to a language model.

Available domain name generator: name ideas checked against the registries

An available domain name generator turns keywords into domain ideas and checks which are unregistered. Enter up to three keywords and pick TLDs; names come from fixed patterns (prefixes like get, suffixes like hq, keyword joins) and the best 60 are checked against each registry's RDAP server and DNS. Likely available isn't guaranteed; your registrar confirms.

Sample result

acmestudio.example looks available. Its registry has no record of it.

Name idea: acmestudio.example
Pattern: Keywords joined
Basis: No RDAP record, no nameservers

What this means for you

A good name to grab at a registrar soon; the registrar confirms it's free before you pay.

How do I generate available domain names from keywords?

Enter one to three keywords, such as coffee roast, separated by spaces or commas.
Tick the TLDs to try. .com and .app are on by default; .io and .co registries publish no RDAP, so names there show unknown unless DNS proves them taken.
Press Generate and check. The 60 shortest, plainest ideas are checked, 20 at a time, against each registry's RDAP server and DNS.
Likely-available names come first. Copy them or download the CSV, then confirm availability and price at a registrar before you decide.

Example

You enter: The keywords acme studio with the TLDs you want ticked.
You get: Ideas built from fixed patterns, such as acmestudio.example (keywords joined), each checked on its registry. acmestudio.example comes back Likely available because the registry has no record and there are no nameservers; taken names are listed as Registered.
Limits: Up to three keywords; the 60 shortest ideas are checked per run, within 100 availability checks a minute per connection.

How do I find an available domain name?

Start from two or three words that describe the business, enter them above and press Generate and check. The tool builds names from fixed patterns, checks the best 60 against the registries, and lists the likely-available ones first. Plain one-word .com names are almost always registered, so the useful ideas are usually a keyword with a short prefix or suffix, two keywords joined, or a different TLD.

Each name is checked the same way as in the bulk domain availability checker: the registry for its TLD comes from IANA's RDAP bootstrap file (RFC 9224), the registry is asked for the name, and DNS is checked for nameservers. No registry record and no nameservers means likely available.

How are the name ideas generated?

From simple, repeatable patterns, with no AI model: each keyword on its own; with a prefix (get, try, use, go, my, hey, join, the); with a suffix (hq, app, labs, mail, hub, now, ly, base); two keywords joined in both orders; and short blends that cut one keyword after its first syllable, such as cofroast from coffee and roast. The same keywords always give the same list.

Ideas are ranked by length and pattern, shortest and plainest first, with the TLDs in the order shown. Only the top 60 are checked per run, which keeps a run inside the lookup limit of 100 domains a minute. To check a different set, change the keywords or TLDs and run again.

Does likely available mean I can register it?

Not always. It means the registry has no record and the name has no nameservers, the two public signals of an unregistered domain. Registries can still hold names back without a record: premium names sold at a higher price, reserved names and blocked trademarks can look free. The registry and your registrar are the source of truth, and the registrar's checkout shows the real price.

Unknown means we couldn't tell, usually because the TLD's registry publishes no RDAP (.io, .co, .me and .de among them when we checked on 19 October 2026) or didn't answer in time. Unknown names are never shown as available. Availability can also change in minutes, so check again at the registrar before you rely on a result.

Who uses this tool, and for what?

Founders: Shortlist names for a new product from two or three keywords, with the likely-available ones already separated from the taken ones.
Agencies: Bring a client a CSV of available-looking options across .com, .app and .dev, then confirm the final picks at the registrar together.
Cold emailers: Find a name for a separate brand or campaign. For variations of an existing brand, the cold email domain generator is the closer fit.

What can’t this tool tell you?

Likely available is not a guarantee: premium, reserved and blocked names can look free. The registry and your registrar are the source of truth.
TLDs without RDAP, including .io, .co, .me and .de, show unknown unless DNS proves the name is registered.
Up to 60 ideas are checked per run, and 100 domains a minute per connection across the domain availability tools.
The patterns are simple and deterministic: they won't invent new words or judge whether a name is a good brand, or whether it clashes with a trademark.
Prices aren't shown; registrars set them, and premium names can cost far more than a standard registration.

Authentication and capacity are half of deliverability.

The other half is who you send to. Every hard bounce counts against the domain and inboxes you are sending from, and nothing in DNS can tell you which addresses on your list are dead.
