computer_chess:wiki:lists:chess_engine_list

This is a list of all available WB/UCI chess engines. 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. Other good sources for this information are Leo Dijksman, Guenther Simon, Eric Terrien - Programmes PC Freeware, Arena Engine Links (administrator:Michael Diosi), Czech Engine List (administrator: Pavel Háse) , Jim Ablett or mirror or alphabetical index 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 following criteria:

the latest date shown on an engine download website
the dated version number (ie: version 0.0.20031118)
the latest date found inside zipped archive files

Note - a survey of engine bugs can be found at the following website RWBC Bugbase for WinBoard and UCI Engines

All programs are assumed to be 32-bit Windows programs unless otherwise noted. 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'.
