Stockfish is a free and open-source chess engine, available for various desktop and mobile platforms. It can be used in chess software through the Universal Chess Interface.

Stockfish is consistently ranked first or near the top of most chess-engine rating lists and is the strongest CPU chess engine in the world. It has won the Top Chess Engine Championship 12 times and the Chess.com Computer Chess Championship 18 times.

Stockfish is developed by Marco Costalba, Joona Kiiski, Gary Linscott, Tord Romstad, Stéphane Nicolet, Stefan Geschwentner, and Joost VandeVondele, with many contributions from a community of open-source developers.It is derived from Glaurung, an open-source engine by Tord Romstad released in 2004.

Stockfish implements an advanced alpha–beta search and uses bitboards. Compared to other engines, it is characterized by its great search depth, due in part to more aggressive pruning, and late move reductions. As of July 2022, Stockfish 15 (4-threaded) achieves an Elo rating of 3540 on the CCRL 40/15 benchmark.
