The Code Book: Learn programming interactively and escape tutorial hell.

Hey Product Hunt! 👋 I’m Otis, the creator of The Code Book. I built this platform because I got incredibly tired of seeing passionate people get stuck in "tutorial hell"—that loop where you endlessly watch programming videos but never actually learn how to build anything on your own. I wanted to make something heavily gamified and hands-on to make learning to code genuinely engaging. The Code Book is a web app structured across 7 "floors" that take you from absolute zero to developer-level concepts. Here is what I built into it: • Interactive lessons paired with immediate coding challenges • XP rewards and daily streak tracking to keep you consistent • Built-in Spaced Repetition (SRS) flashcards for long-term retention • Voice narration and focus timers to help you lock in and study It is 100% free, fully responsive on both mobile and desktop, and requires absolutely no installation. You can even jump in as a guest to try it out without creating an account. I'm looking for about 20 testers from this amazing community to jump in, try the lessons, and absolutely break things! What breaks? What's confusing? What feels great? Drop your thoughts below—I'll be right here in the comments to chat and answer questions!
