Mockit

Most mockup tools make you download Photoshop templates, install a Figma plugin, or wait for a server to render your image. Mockit throws all of that out. It runs 100% in your browser using CSS 3D transforms, no upload, no account, no waiting. The rendering happens on your local hardware, which means zero lag and zero server costs on our end. You get professionally lit, physically accurate 3D mockups for iPhone, Android, MacBook, tablet, Apple Watch, Smart TV, and more. The standout features: real-time parallax that reacts to your cursor like a physical object in a studio, Apple-style blurred floor shadows, glassmorphism backgrounds, a canvas crop selector for any format (9:16, 1:1, 16:9), and a "Surprise Me" button that instantly generates a gorgeous composition. Export to PNG is done locally — nothing ever touches a server.
