Why I created LilyChess
★★★★★
As a competitive player, I quickly hit the limits of standard analysis on Lichess or Chess.com. To prepare my openings and analyze my games, I switched to HIARCS, but the calculations took entire days on my computer and drained my battery — an unthinkable constraint during a tournament! I then looked into cloud solutions like Chessify, but the experience was very frustrating: the tool would regularly crash in the middle of analyzing a complete PGN, forcing me to start over from scratch, all with an opaque and overpriced credit system. Tired of these inadequate tools, I decided to create LilyChess Lab. My goal? To offer exactly the opposite: a cloud platform with absolute reliability that never stops mid-analysis, powered by Stockfish 18, and with 100% transparent pricing. It's the chess laboratory I always dreamed of having: built by a player, for players.
