Chessdriller is an open-source app for spaced repetition of chess openings. It's a free and libre alternative to the spaced-repetition features of Chessable, ChessTempo, Chessmadra, ChessHQ, Chess Position Trainer, Bookup, Listudy, etc.
To try Chessdriller out, just log in with Lichess to get started. A Lichess account is needed since your repertoire is stored as Lichess studies.
Feel free to email me about any issues, feedback or suggestions, or just to chat about chess. Github issues and PRs are also welcome.
See TODO.md for planned features.
If you'd like to host your own instance of Chessdriller, e.g. to contribute code or for privacy reasons, you can find simple instructions in BUILD.md.
