ChessX is a free Open Source Chess Database for Linux, Windows, and Mac OS X. The project uses Qt library to create modern, portable graphical interface. Current development is aimed at providing full featured PGN database. Afterwards we will add more flexible native format.

History

The project was started after development of Scid halted and contact with the author was lost. Initially, ChessX was to be a community maintained version of Scid called "New Scid". However, after some initial development, it was decided to break away from the old code so that new ideas and modern interface can be implemented.
