Hey Product Hunt! 👋 I built CodeCity because I couldn't find a platform that taught coding the way developers actually think — through doing, not watching. Every challenge is a real problem. AI grades your code on correctness, efficiency, readability, and best practices. You earn XP, unlock paths, and actually see your skills improve over time. 13 learning paths covering Python, Java, AI, and more. Free to try — no signup required for your first challenge. Would love your feedback: are the early challenges too easy, too hard, or just right? 🙏Copy
