Hi Product Hunt! 👋 I built OmniBoard Pro to solve a simple problem: most digital whiteboards are either bloated with paywalls and mandatory sign-ups or too laggy for quick calculations and graph sketching. Whether you're a student, educator, or researcher working on math, physics, or software diagrams, you need an instant, friction-free canvas. OmniBoard Pro is 100% free, fully open-source, and requires zero registration—just open the link and start sketching on an infinite board. Key Highlights: - Infinite Canvas with smooth pan and zoom - Optimized STEM & drawing tools - Instant web access with zero sign-up - Ultra-lightweight performance I'd love to hear your feedback, feature ideas, and suggestions on how to make OmniBoard Pro even better! What features would you like to see next?
