XBoard

Home * User Interface * GUI * XBoard

XBoard is a graphical user interface for the Chess Engine Communication Protocol running under the Unix (Posix) operating system based on the X Window System, originally developed by Tim Mann as GNU Chess interface. In Fall 2013, Joshua Pettus managed to port XBoard to MAC OS X using the native Quarz Graphics layer.
