What are some websites based on the lichess source code?

I want to see how the lichess source code has been used by other people, and to use it myself. I know there are some platforms for playing other games like shogi, etc but i am not able to find those links. Can you list some websites?

There is also lichess.dev ,which is for developers that are testing lichess features.

dont knwo of anby

@padawan_ani
lishogi.org/

Regarding chesscup dot org, they take puzzles from Lichess but there is no mention about it being open source in their About page, nor does the site look like lichess, lishogi, lidraughts sites.
Or am I overlooking something ?
