Turn raw app screenshots into stunning, high-fidelity device mockups in seconds with MockupBuilder! Whether you are a developer preparing assets for the App Store, an indie builder posting on social media, or a designer compiling a pitch presentation, MockupBuilder wraps your flat screen captures in realistic device frames. Adjust 3D perspectives, add shadows, apply styled text overlays, and draw attention to interface changes with advanced vector markups. Key Features: Realistic Device Bezels & Contrast Glow Wrap screenshots in premium frames including the latest iPhone 16 Pro, MacBook Pro, Safari Web Browser, and minimalist cards. Toggle a sharp, neon-blue Border Contrast Glow outline to make mockups stand out beautifully against matching dark background colors. Change canvas aspect ratios instantly to match App Store specifications, Instagram feeds, or LinkedIn posts. ASO-Specific App Store Presets Accelerate your App Store asset design with direct ASO presets! Instantly configure canvas aspect ratios, frames, and background layers for iPhone 6.7", iPhone 5.5", and iPad 12.9" layouts in one tap. Simulated Social Feed Previews Inspect your mockups in-editor before posting. Simulate real-world timelines by wrapping your mockup canvas inside realistic Twitter/X tweets, LinkedIn posts, and Product Hunt launch cards to check feed cropping and alignment. Background & Backdrop Customization Go beyond gradients: Choose solid background colors, input custom color values using the HEX input bar, or upload your own custom photos as canvas backdrops. Access an expanded suite of premium linear gradient presets including Aurora Borealis, Neon Coral, and Mystic Glow. Before & After Split Slider Highlight app updates, design overhauls, or light/dark-mode themes side-by-side. Add a split-screen draggable slider comparison overlay directly onto your exported mockup cards. Styled Vector Annotations Focus user attention on micro-interactions using magnification spotlight zoom lenses. Superimpose customizable callout cards and adjustable pointer arrows. Frustration-Free History Experiment safely with a dedicated local history engine. Undo and redo layout changes sequentially on the active stack.
