En Croissant is an open-source, cross-platform chess GUI built with Tauri, React, and Rust. It combines game analysis with UCI engines, a personal game database, and repertoire training with spaced repetition.

Use cases

  • analyze my chess games with stockfish
  • import my lichess and chess.com games into one database
  • build an opening repertoire and train it
  • manage and install chess engines easily
  • search chess databases for positions
  • get an evaluation graph and best move suggestions for my games

When to choose

  • you want a free, open-source alternative to ChessBase for game analysis and databases
  • you play on both lichess and chess.com and want your games in one place
  • you want multi-engine UCI analysis with a modern desktop UI
  • you want spaced-repetition training for your opening repertoire

When to avoid

  • you only want to play chess online rather than analyze or study
  • you need a lightweight command-line chess tool
  • you require features only available in commercial chess software like ChessBase's publishing ecosystem
