DeepVariations is a desktop chess workspace for analysis, study and training. It brings engine analysis, Game Review, databases, PowerBook, opening preparation, Live Broadcast, repertoire training, puzzles and endgame practice together around the same board and notation.
Stockfish 19 is included for local analysis. DeepVariations Coach can add local natural-language explanations to reviewed positions while the chess engine remains the source of evaluations and critical lines.
The Linux edition is free to use and does not require license activation.
The Flatpak edition includes the bundled Stockfish engine but does not support adding external local UCI engines. Users who need external UCI engine support should use the DEB or RPM edition from deepvariations.com.
Adds the Lichess Broadcast Multi-Board overview with up to eight live games, last-move and side-to-move indicators, and locally ticking clocks. Improves broadcast workspace restart and round selection, duplicate game detection during database import, and puzzle setup move presentation.
