Chess Variant GUIs

LiGround is a modern, cross-platform chess variant GUI for lichess variants and regional variants. As it is a rather new project the set of features is rather limited, but working well for basic analysis and game play. Compatible with UCI engines, especially Fairy-Stockfish, since LiGround’s rule implementation is based on it.

Cutechess mainly a chess (variant) engine tournament manager, with both a command line and a graphical user interface. Also supportd game play against engines, but does not have analysis features.

PyChess GUI, not to be confused with the pychess variants website, supports several chess variants for 8x8 boards. It has features for analysis and game play, and is compatible to UCI and CECP chess variant engines.
