Hey Product Hunt! 👋 I'm Vivek, the maker of CodeArena. I built CodeArena because I was frustrated with existing coding platforms. They either hide their best features behind massive paywalls, or their "AI helpers" just dump the complete solution instead of actually teaching you. CodeArena fixes this. It’s an entirely free, open-source competitive programming platform where you can: ⚔️ Challenge other developers to real-time 1v1 coding duels. 🤖 Get unstuck with a context-aware AI Mentor (powered by Google Gemini) that analyzes your code and asks guiding questions instead of spoiling the answer. 🏆 Track your progress and climb the global leaderboard. Tech Stack: React, Node.js, Express, MongoDB, Socket.io, and the Gemini API. I spent months building this and would absolutely love your feedback on the UI, the AI's mentoring style, or the real-time dueling! Drop your thoughts below, I will be replying to everyone! 👇
