CodeArena
Competitive coding platform with a built-in AI mentor.
Level up your coding skills with CodeArena. Practice algorithm problems or challenge other developers to real-time coding duels.
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! 👇

Who hunted CodeArena?
CodeArena was hunted by Vivek Kumar Sulaniya. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
