Play Oxid'

Oxid' is the chess engine I have been writing in Rust from near scratch, and this is it running in your browser: the same search and the same neural network as the native build, compiled to WebAssembly. Nothing is sent to a server, so the engine is thinking on your machine, in a background thread, at whatever speed your laptop manages.

The engine and its network weigh about 2.4MB, so nothing downloads until you pick a colour below. I wrote the story of building it in a series of posts, and the source lives on GitHub.

Moves are shown the way the engine speaks them, from square to square. The browser build is single-threaded and has no opening book or endgame tablebases, so it plays a little below the 2700 Elo the native build is rated at.
