Hey Product Hunt! Excited to share 4mapper with you! Behind 4mapper: I'm a full-stack developer who's been working with projection mapping for art installations and live performances. The problem? Most projection mapping software requires heavy installations, specific OS versions, or powerful dedicated machines. I wanted something more accessible - that you could open on any laptop, test ideas quickly, and use for both prototyping and live shows. So I built 4mapper entirely in the browser using HTML5, JavaScript, and perspective transform algorithms. What you can do right now: • Open 4mapper.com • Upload your video or image • Drag the corner points to match your projection surface • Hit play and you're projecting Current features: ✅ Multi-scene management for live switching ✅ Real-time preview ✅ Video + image support ✅ Perspective correction with visual calibration ✅ Cloud storage for your projects ✅ PRO tier with 5GB storage and advanced features (live widget) What's next: I'm working on ESP32 integration for hardware remote control, timeline animations, and more advanced effects. I'd love to hear your feedback! What features would make this more useful for your creative projects? Try it now: https://4mapper.com Thanks for the support!
