A related fork [0] powers the web-based tool on Lichess [1]. It's a notable example of WASM in widespread use (I believe it's WASM-by-default on every browser now).

FYI - the version you linked to is the “Slower fallback versions of Stockfish for browsers (C++, WebAssembly, JavaScript)” according to Lichess.

EDIT: nevermind, looks like you changed the link.

Thanks, corrected link!

I wonder why Lichess doesn't use multithreading, it was working in a previous version. I mean Brave can use 2 threads but I've seen 8/16 max threads before.

Lichess doesn’t?

There’s reference to thread support in the library documentation.

Lichess on chrome let's me use however many logical processors I have. For whatever reason I can only get a single thread on Firefox.

I'm not sure why either, because a while back I could use how ever many threads I wanted on Firefox.

For me it's:

Chrome: 15 threads, 1 GB memory

Firefox: 1 thread, 256 MB

Brave: 2 threads, 128 MB

What a puzzle. I have:

Firefox: 7 threads, 256 MB

Brave: 3 threads, 1 GB

You can configure how many CPUs and memory to use under settings

I know, that's what I'm talking about
