Hi Product Hunt! 👋 I’m Kapil, and I built Brain Rivals to answer one simple question: How fast is your brain today? I wanted to create a space that moves beyond casual gaming and focuses on pure cognitive reaction time. Whether you're a developer looking to stay sharp or just curious about your mental agility, Brain Rivals gives you the data to track your progress and see how you stack up against the community. The app is optimized for extreme low-latency (crucial for reaction testing!) using a Next.js and Coolify setup on Hetzner. I’m building this in public and would love to hear your thoughts on what other cognitive metrics we should track next! Let's see those reaction scores! 🧠⚡
