Hi Product Hunt! I'm Simon, an engineering student and chess enthusiast who built PenguinChess over the past few months.
I wanted a free alternative to existing platforms that covers the full training journey - from openings to endgames - without forcing users to create an account or pay for basic features. So I built it myself with React and FastAPI.
Would love to hear your honest feedback, especially if you're a chess player - what's missing? What could be better?
Happy to answer any questions!
