Lucas Chess

Lucas Chess is an open-source chess program and training suite developed primarily by Lucas Monge. It is designed to provide players with a wide range of training tools, including thousands of levels and various chess engines to play against. The project is a community-driven individual development effort rather than a corporate product.

While the software is distributed globally via digital download, its development origin is Spain. The program is built on Python and incorporates many open-source chess engines like Stockfish. Because it is free and open-source software (FOSS), there is no corporate parent company or stock-listed entity that owns it; it is managed by the developer and the open-source community.
