Chess training comparison · 2026
Listudy vs DevelopChess
Listudy is the leaner choice for free, open spaced repetition—especially when you already have a PGN repertoire. DevelopChess is the broader guided choice for deciding what to train from games and tracking several skills together.
The short answer
Choose by the work you want to repeat.
The real difference
Listudy and DevelopChess start from different training units.
Listudy is a libre training site centered on spaced repetition. It lets players study openings, tactics, endgames, and community material, and is especially useful for rehearsing a repertoire represented as PGN.
DevelopChess does not ask the player to arrive with a prepared study. A PGN can be a played game, not a repertoire; the system finds instructive moments and connects them to a wider skill model. That removes setup but gives the learner less authoring control.
