Grabo

什麼是 Grabo？

Grabo is a free 3D mockup video maker for apps, 100% client-side. Animate camera and device with keyframes, add text, lights and backgrounds, then export as MP4 or WebM at full resolution. Export renders frame-by-frame and encodes with WebCodecs right in the browser, with no server, no account and no watermark. Built solo with vanilla JS, Three.js and GSAP after getting tired of mockup tools that watermark, cap resolution, or require a subscription.
