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 Dan Sears and Chris Sears as a chess GUI for GNU Chess only. In 1991 Tim Mann took over, became the main developer and he continued developing it parallelly with WinBoard. In Fall 2013, Joshua Pettus managed to port XBoard to MAC OS X using the native Quarz Graphics layer. When Harm Geert Muller took over the project, he focused on WinBoard only and XBoard was abandoned since.
