Native macOS app for indie developers who want cinematic 3D product visuals — without hiring a designer or learning Blender.

Built for developers who ship quality apps but struggle to show it in their marketing. → Free to use. Pay only when you export ($15 once / $149 unlimited) → No subscription. No account. No cloud.

Hey Product Hunt! 👋 I'm David, the solo developer behind Lumen 3D Marketing Studio. I built this because I kept running into the same problem: my apps looked polished, but my App Store screenshots looked flat. Every tool I tried was either a web app with generic templates, or required learning a full 3D pipeline. So I spent months building a native macOS app with SceneKit — photorealistic device mockups, real PBR materials, camera animation with a keyframe timeline, and 4K export. Everything runs locally, nothing goes to the cloud. It's free to download and use. You only pay when you export. 🎁 Launch offer: use code WELCOMELUMEN at checkout for 15% off the perpetual license. Would love to hear what you think — especially if you're an indie dev who's felt this pain. Happy to answer any questions below! 🙏
