Hi Product Hunt 👋 I built this because I got stuck updating my own portfolio. Every mockup generator gives you one fixed camera angle, so my screens always ended up too small or tilted the wrong way, with nothing I could do about it. So the whole idea of Mocku is that the device is a real 3D object, not a flat template. You rotate it, light it, set the shadow, and arrange props and backdrops around it. It all renders with Three.js in the browser, and what you see in the editor is exactly what exports. One more thing worth saying: this is one of my first vibe coded projects. No coding background, no wireframes, no hi-fi designs. Just Codex and Claude, prompting and iterating until it felt right. The AI wrote the code and I made the product decisions. Free gives you the full editor and every 3D device. Pro adds 3x exports, the full scene library, and video export. Would love your feedback, especially on anything that feels slow or confusing. Thanks! Note: the editor needs a bigger screen, so open it on desktop.
