Pikafish is a free, open source, and strong UCI xiangqi engine derived from Stockfish that analyzes xiangqi positions and computes the optimal moves.

Pikafish does not include a graphical user interface (GUI) that is required to display a xiangqi board and to make it easy to input moves. Several Free GUIs are developed independently from Pikafish and are available online. Read the documentation for your GUI of choice for information about how to use Pikafish with it.
