Janggi

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. Currently is the only website where all major regional chess variants can be played and analyzed. Not to be confused with the PyChess GUI.

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.

WinBoard/XBoard is an old but very feature rich chess variant GUI supporting a large variety of chess variants, including user/engine defined games. Not as modern and stable as other GUIs, but still one of the most used variant GUIs. Compatible with CECP/XBoard engines.

Gulbi is a Korean Janggi GUI designed for compatibility with Fairy-Stockfish.

Fairyground serves as a playground to try out Fairy-Stockfish online with custom variants, enabling game play and interactive analysis.

Strongest open source chess variant engine in many variants. Configurable for custom variants and trainable with NNUE (neural networks). Used by many chess variant websites such as Lichess, Pychess, Lishogi, etc.
