OnePixel

Overlay comparison tool for mobile implementations and Figma designs. Features automatic viewport scaling and transparent overlay mode to identify alignment and spacing differences. Streamlines design QA process by providing instant visual feedback on implementation accuracy.

OnePixel Plugin compares design and developer screens for mobile viewports to identify pixel-perfect differences and alignment issues. To start comparing, select a design screen in your Figma file (your base screen), and upload a developer screen which you want to test.

For accurate results, ensure both Design and Dev screens have identical viewport width (e.g., 360 to 360, 393 to 393, etc.).

Key Features:• Transparent overlay mode for comparing implementation with design• Automatic viewport scaling to design dimensions• Visual detection of alignment and spacing discrepancies• Optimized for mobile development workflows• Real-time comparison without manual adjustments
