Fritz is a German chess program originally developed for Chessbase by Frans Morsch based on his Quest program, ported to DOS, and then Windows by Mathias Feist. With version 13, Morsch retired, and his engine was first replaced by Gyula Horvath's Pandix, and then with Fritz 15, Vasik Rajlich's Rybka. Fritz 17 switched to the Ginkgo engine, written by Frank Schneider.

The latest version of the consumer product is Fritz 19. This version supports 64-bit hardware and multiprocessing by default.
