What's lichess's alt website?

I was browsing when I found the website. It has less people than lichess.org (the main). What is it?

There's lichess.dev , which is for beta-testing AFAIK. Then there's lidraughts.org , which is for draughts. I think there's another site that uses Lichess's UI for bughouse too.

WHATS IT CALLED

lichess.dev (its called dev lichess or smth like that)

There is lishogi.org for shogi
