Other analysis engines than Stockfish?

I see that it is now possible to choose several analysis engines (in fact different versions of Stockfish) to analyze. It might be interesting to also install chess analysis engines other than Stockfish. There are many other free engines that present sometimes alternative and interesting gaming visions ("game style") compared to Stockfish.

You actually can use any external engine installed on your PC with Lichess. Currently it's implemented poorly, just as proof of concept, but it works.

Google for "Lichess external engine".

It would require web assembly ports of those language. For example, I'm not aware of a web assembly port of Crystal, or Lc0.
