Short domain name finder: pronounceable 3, 4 and 5 letter names that are still free

In short: Choose a letter pattern like CVCV, optionally the first letters and an extension, and see which pronounceable 3 to 5 letter names look unregistered. Limit: Likely available is not a guarantee: premium, reserved and blocked names can look free.

A short domain name finder lists pronounceable names of three to five letters and checks which are unregistered. Pick a pattern (CVC, CVCV, CVCC and others, where C is a consonant and V a vowel), optionally the first letters, and an extension; 60 names a run are checked against the registry's RDAP server and DNS, and the likely-available ones come first. Likely available is not guaranteed; the registrar confirms.

Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing

Extension

.io, .ai and .co registries publish no RDAP, so those names show unknown unless DNS proves them taken.

Names are built from the pattern with consonants and vowels that read as a word, rude combinations removed, in a fixed order. Each run checks 60; press the button again with the same settings for the next 60. Every name is checked against its registry’s RDAP server and DNS.

How do I find a short domain name that is available?

  1. Pick a pattern. CVCV gives four-letter names like zeno; CVC gives three-letter names; CVCVC gives five.
  2. Optionally type up to three starting letters, such as ka, and choose one extension. .com, .net, .org, .app and .dev can be shown as likely available.
  3. Press Find short names. 60 names from the pattern are checked, 20 at a time, against each registry's RDAP server and DNS.
  4. Press the button again with the same settings for the next 60. Copy the likely-available names or download the CSV, then confirm the price at a registrar.

Example

You enter
Pattern CVCV (consonant, vowel, consonant, vowel), no starting letters, extension .com.
You get
60 of the 8,054 names that fit the pattern, such as cowu.com, zito.com and rigo.com, each marked Likely available, Registered or Unknown, with likely available first. Press the button again for the next 60.
Limits
60 names a run, checked 20 at a time against each registry's RDAP server and DNS; 100 domains a minute per connection.

Which short domain names are still available?

Almost every real word and every three-letter or four-letter .com made of plain letters has been registered for years, so a short name that is free is usually not a dictionary word. What is left in quantity are coined names that follow the sound of a language: consonant and vowel in turn, like zeno, kavi or lumo. This tool builds those from a fixed pattern, then checks them.

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

What do the patterns mean?

C stands for a consonant and V for a vowel. CVCV is a consonant, a vowel, a consonant and a vowel, so nova and zeno fit. CVC is three letters, VCVC starts on a vowel (oban), CVCC ends in a common consonant pair such as ld, nd or rt (melt), CCVC starts with a pair such as br or st (brim), CVVC has two vowels in the middle (boat), and CVCVC gives five letters.

The letters q, x and y are left out, and the consonant pairs are limited to ones English uses at that spot, so every name can be said. A short list of rude combinations is removed. Names are put in a fixed order by a hash of the name, with no randomness: the same settings always give the same 60, and the next press gives the next 60. Short names are not a measure of brand quality; they are easy to type and hard to find free.

Does likely available mean I can register it?

Not always. Short names are the ones registries most often hold back as premium, sold at a price well above a standard registration, and reserved or blocked names can look free too. The registry and your registrar are the source of truth, and the registrar shows the price.

Unknown means we could not tell, usually because the extension's registry publishes no RDAP (.io, .ai and .co when we checked on 19 October 2026). Unknown names are never shown as available, and availability can change in minutes, so check again at the registrar before you rely on a result.

Who uses this tool, and for what?

Founders
Find a short coined name for a product, and shortlist the ones that are free before anyone gets attached to a name.
Cold emailers
Look for a short domain for a separate sending brand. Brand variations of an existing name are easier in the cold email domain finder.
Domain investors
Scan one pattern and one extension for unregistered names, then check each at a registrar for premium pricing.

What can’t this tool tell you?

  • Likely available is not a guarantee: premium, reserved and blocked names can look free.
  • Extensions without RDAP, including .io, .ai and .co, show unknown unless DNS proves the name is registered.
  • 60 names are checked a run, and 100 domains a minute per connection across the domain availability tools.
  • The tool builds names from sound patterns; it can't tell whether a name means something rude or unlucky in another language, or whether it clashes with a trademark.
  • Prices are not shown; registrars set them.

Common questions

How do I find an available four-letter domain?
Choose CVCV, CVCC or another four-letter pattern here, pick an extension and run it. Each run checks 60 names against the registry's RDAP server and DNS and lists the likely-available ones first.
Is this short domain finder free?
Yes, it is a free tool with no account or card. Each run checks 60 names, and one connection can check 100 domains a minute across the domain availability tools.
Are the names random?
No. They come from a fixed pattern in a fixed order, so the same settings give the same names. The button gives the next 60 each time you press it with the same settings.
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. Premium, reserved and blocked names can still look free, so the registrar's checkout, with its price, is the final word.
Why do .io, .ai and .co names show unknown?
Their registries don't publish RDAP in IANA's directory (checked 19 October 2026), so there is no registry record to read. A name with nameservers in DNS shows as registered; otherwise it shows unknown, never available. Check those at a registrar.
