About Nunchiyo

Nunchiyo is a domain intelligence database. It records who owns a website, how that website makes money, which ad networks, trackers and affiliate networks run on it, and the date any of that changed.

What it does

Nunchiyo reads files websites publish themselves — the ad seller lists, the code loaded into a page, ownership and financial disclosures — and writes down what it finds. It reads the same files again on a schedule, so a change in who pays for a site has a date attached to it.

What it will not do

Nunchiyo does not rate, score, or judge. There is no good or bad site here, and colour in the interface marks a category, never a quality. Every stored fact carries the link it was read from and the date it was read, so you can check it rather than trust us. Where nothing has been found, it says so instead of guessing.

Who it is for

Journalists, researchers, teachers, librarians and anyone who wants to know who is being paid behind the pages they read.
