Sources & Method
The site uses public data only. Here is which, and what we do with it.
Names
The name statistics come from the national file of the Social Security Administration, which records births registered in the United States since 1880. We keep 105,966 names and their yearly series.
That dataset is public domain, released by a United States federal agency. Edition used SSA baby names (births 1880-2025).
What the Numbers Say, and What They Do Not
The SSA publishes nothing below five births a year, so a name given four times in 1930 is absent from the data and from this site. What you read here counts registered births, not people alive today.
Yearly ranks are ours. The SSA publishes counts but no ranking, so we order the names of each year and sex by the counts it does publish. A name below the five-birth floor has no rank because it has no published count.
Words
The English word list comes from Wiktionary, released under CC BY-SA, and from SCOWL, released under an MIT-like licence. We take only the nomenclature, that is the word forms and their part of speech. No definition is copied or reworded.
The database holds 847,262 forms, of which 239,364 belong to current vocabulary. That split keeps result lists readable without taking anything away from the solver.
Licences
Two of the word list licences ask that their notice appear in the documentation of any product built on them. Here they are, word for word.

Method
Two terms are anagrams when they use exactly the same letters. To compare them, each term is reduced to its sorted letters, without accents or capitals.
Accents drop out of that comparison, so CAFE and CAFÉ form a single entry. Every spelling is shown on the page.
Data is imported and checked offline, then served as is. The site queries no outside service while you visit.
