Stockfish is a free, powerful UCI chess engine written in C++, derived from Glaurung 2.1. It is not a complete chess program and requires a UCI-compatible GUI to be used comfortably.

Use cases

  • play chess against a strong engine
  • analyze chess positions and find best moves
  • run a chess engine inside a UCI-compatible GUI
  • limit engine strength to a target Elo for training
  • get multiple candidate lines with MultiPV analysis
  • integrate a chess engine into chess software via UCI protocol

When to choose

  • you need a top-strength open-source chess engine
  • you want a UCI engine to plug into a chess GUI like Arena or Cute Chess
  • you need configurable engine strength for training or handicap play
  • you want deep position analysis with MultiPV

When to avoid

  • you want a complete chess program with a graphical board UI
  • you need a chess database or opening book manager
  • you want a non-UCI protocol engine
