The best 2021 chess programs:
These are the best and the strongest chess programs ever for sure, there's no Lc0, Komodo or Houdini that can face them. Plus they are completely free.
You need a graphical interfact to make them work, such as Fritz (Windows), the free Arena (Windows and Linux), SCiD or Droidfish (Android). Any of these programs (chess engines) must be installed on said interfaces.

Since the Stockfish derivates are now built with large embedded networks the resulting download is bigger. This website uses the Responsible Download Technology® : you can download only the version related to the operating system you are using when browsing here. This was done to prevent waste of bandwidth and people downloading programs just to throwing them in the trash. For the private part of the site the Responsible Download Technology® is disabled, so the downloaders are free to get ALL the programs browsing from any platform)
