Hey Product Hunt 👋 I kept noticing the same tricks across Duolingo, Spotify, Uber, Etsy streaks that pull you back, pricing pages that nudge you to premium, checkout flows with zero friction. So I started screenshotting them, digging into the psychology, and organizing everything into a system. That became Product Patterns: • 300+ real UX patterns, each with the psychology, why it works, and when it fails • 32 psychological theories + 72 cognitive biases, cross-linked to the patterns that use them • Anti-patterns — real screenshots of what NOT to do, with the numbers • 33 page-by-page frameworks (onboarding, pricing, churn, habits, checkout…) The part I'm most excited about: it's fully readable by AI agents. Drop the Cursor/Claude skill in, or point your agent at the MCP server, and it pulls real patterns + psychology straight into your build, instead of inventing generic advice. It's free and there's no signup. Two questions for you all: 1. What's the one pattern you wish every product copied? 2. And the one dark pattern you wish would die? I'll be here all day, would love your feedback 🙏
