Runs in your browserDomains & URLs
Domain list analyzer
Analyze large lists of domains or URLs without uploading them anywhere: totals, unique hostnames and registered domains, TLD distribution, IDN/hyphen/digit counts, length statistics and a report of invalid lines. Files are read locally in your browser.

How to use
- 1Paste a list or load a .txt or .csv file; for CSV the first column is used.
- 2Press Analyze.
- 3Review the totals, the suffix distribution and the most frequent domains.
- 4Export the registered domains with their counts as CSV or JSON; invalid lines are listed separately.
Lines without a usable hostname: plain words, broken URLs or names without a dot. IP addresses are counted separately and are not treated as domains.
A hostname has a subdomain when something other than www sits in front of its registered domain, which is determined with the Public Suffix List.
Hundreds of thousands of lines are fine. The analysis runs in your browser and nothing is uploaded.
