A site that shows a list of popular sites that I visit or am logged in to?

Question

Anonymity

About a year ago, I came across a link. In my opinion, I saw it on habrahabr.ru If you follow the link, I will see a list of sites that I visit or sites in which I am logged in. The list of these sites was from the most popular social networks: linkedin, vk, facebook, twitter, etc. I don’t know how this list is formed, but now it became very interesting to me.
Please tell me what the link is. Thank you.
PS I think this project was on github
