How Domain Name Finder works, start to finish.
Domain Name Finder helps you discover available domain names by combining your own lists of words and checking each combination for availability. The typical flow is:
- Word Lists — build lists of words (prefixes, suffixes, brand terms, industry terms, etc.).
- Builder — pick two lists and a set of TLDs
(
.com,.io, …). The engine generates every combination (the "Cartesian product") and checks each one for availability. - Searches — each run is saved so you can revisit its results, re-check, or export them.
- Tools — other generators (typos, hyphenated, pronounceable, thesaurus, etc.) for when a straight combination isn't what you want.
- Favorites — bookmark the names you like.
A named collection of words you control — for
example a brand list (aarons,
cloud) and a suffix list
(hub, hq, labs). The
Builder pairs two lists together.
It takes the left list and the right list and produces every left+right combination, once per selected TLD. Two 100-word lists across 3 TLDs = 100 × 100 × 3 = 30,000 names to check. The estimated count is shown before you run, so you don't accidentally generate millions.
Each generated name is then checked for availability via DNS or RDAP.
No. A search is a snapshot taken when it runs. Adding a word to a list afterward does not change, break, or appear in any existing search.
To include newly added words, run a New Search. (A future "Rebuild" feature will let you append just the new combinations to an existing search.)
Recheck All re-tests the availability of the names already in that search — useful because a domain can be registered or dropped over time. It does not regenerate combinations and does not pick up newly added words.
A New Search regenerates the whole combination set from the lists as they are right now.
A "header row" is a first line naming the column (like
word) rather than data. The toggle is on both the
Import and Export panels:
- Import — tick "First row is a header" only if your file's first line is a column name. If your CSV starts straight into data (no column name), leave it off so the first line is imported as a word.
- Export — tick "Include header row" to write
a
word/domain,extensionfirst line; otherwise the file is pure data.
Your last choice is remembered as your default. Invisible byte-order-marks (which Excel sometimes adds) are stripped automatically on import.
On a list's edit page you can: type one word and
press Enter; click "Paste many words at once" and paste a
whole column or comma-separated list; or use Import
to upload a .txt/.csv file. Duplicates
and invalid characters are handled for you in every case.
They're two ways to tell whether a domain is taken.
RDAP (recommended) is the official successor to WHOIS — it queries the registry directly for a definitive answer. More accurate, but slower (~300ms per domain) and rate-limited by some TLDs.
DNS Check is faster and has no rate limit. It checks whether the domain resolves, which is a reliable proxy for "registered" — but technically a domain can be registered without DNS records. Best for large jobs.
