Shogi

PyChess is a chess variants website trying to provide the look and feel of lichess. It supports a large variety of variants, including analysis with and play against Fairy-Stockfish.

LiGround is a modern, cross-platform chess variant GUI for lichess variants and regional variants.

Compatible with UCI engines, especially Fairy-Stockfish, since LiGround’s rule implementation is based on it.
