computer_chess:wiki:lists:chess_engine_list

This is a list of all available XB/UCI chess engines that run on Linux, Mac, and/or Windows. The most recently released engines can always be found at the top of the list. New engines are added as I find them. All engines are tracked for updates on an irregular basis, usually every week or two. Other miscellaneous sources of chess engine information are Guenther Simon, Eric Terrien - Programmes PC Freeware. Older engines are available from: Czech Engine List (administrator: Pavel Háse) , and Norbert Raimund Leisner,hosted by Kirill Kryukov. Many Mac builds are available from Michael Byrne, contact him for more information.

Abbreviations:
FRC: Fischer Random Chess, also known as Chess 960
mp: multiprocessor
XB: XBoard, also known as WinBoard and as Chess Engine Communication Protocol
UCI: also known as Universal Chess Interface

Latest dates may vary from other sources; New dates are determined according to the date that I add it to this list and may have nothing to do with an actual release date.
