## What it is
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
