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 always added as they are announced/updated. All engines are tracked for updates on a regular basis, usually every day or two. Other miscellaneous sources of chess engine information are Guenther Simon, Eric Terrien - Programmes PC Freeware, Arena Engine Links (administrator: Michael Diosi), Czech Engine List (administrator: Pavel Háse) , Jim Ablett builds and Jim Ablett builds, and Norbert Raimund Leisner, mostly old engines are hosted with kind permission on Kirill Kryukov´s server.

You can keep track of daily engine updates by reading the update posts at the Computer-Chess Wiki Forum, also known as the CCW Forum.

Latest dates may vary from other sources; New dates are determined according to the date that I found it.
Note - a survey of engine bugs can be found at the following website RWBC Bugbase for WinBoard and UCI Engines

For your convenience, foreign-language sites are translated to English by Google. This can cause confusion, ie: the chess engine named 'Alfil' (a Spanish language name) gets translated to 'Bishop'.
