Kagi feels like it is for the user, right? On the other hand I don't really see a page in the documentation that lists all the sources Kagi can scrape from. Even if it's anonymous, it would be good for transparency to state all the sources you have, so users know where are their anonymous searches are going.
Currently we have some insights on search sources, but it's pretty vague. That page could be updated with an up to date list of sources that are actually used by Kagi. Zac talked about 65 different sources here, would be nice to know what are those.
