List of free and open source chess applications

This is a list of chess applications that I personally use and recommend. It was posted in reddit https://www.reddit.com/r/chess/comments/cdjd59/list_of_free_and_open_source_chess_applications/ but it was removed and ornicar commented that it was ok to repost it here, so here it is!

Thanks a lot :). It's a shame that it was removed from Reddit. I think Scid is open source as well.

These are useful programs. - http://scid.sourceforge.net/ A great database program with a database. - http://scidvspc.sourceforge.net/ An updated version. - http://innokuo.altervista.org/chesshero.html A tactics trainer that allows you to change various elements with sample PGNs. (This is a problem with the "pick a random position" feature.)

http://scidb.sourceforge.net/ A rewrite of SCID, supports ChessBase databases. http://chessx.sourceforge.net/ Another database program. https://github.com/lukasmonk/lucaschess Lucas Chess, play and train

https://github.com/supertorpe/chessendgametraining app/webapp to practice a variety of well organized set of chess endgames
