Design Token Extractor

The extension automatically scans every element on a webpage to extract three primary categories of design tokens: 1. Color Tokens: The extension identifies and extracts all color values used throughout the page, including background colors, text colors, and border colors. Each color is presented in both hexadecimal and RGB formats, with visual color swatches for easy identification. The system automatically deduplicates colors, showing only unique values to help you understand the complete color palette of any website. 2. Spacing Tokens: All spacing values are extracted and categorized by type, including margins, padding, and gap values. The extension provides contextual information showing which HTML elements use specific spacing values, making it easy to understand how spacing is applied throughout the design. This helps identify spacing systems, rhythm patterns, and design consistency. 3. Typography Tokens: Complete typography analysis includes font families, font sizes, font weights, and line heights. The extension groups typography combinations together, showing which font families are paired with specific sizes and weights. Additionally, it displays actual text samples from the page, allowing you to see typography in context and understand how different type combinations are used. Live Page Editor Beyond extraction, Design Extractor includes a professional live editing mode that functions similarly to WordPress page builders. When enabled, you can: - Click any element on the page to select it - View all computed styles in a dedicated sidebar panel - Edit typography properties including font family, font size, font weight, line height, and text color in real-time - Modify background colors and border colors with a visual color picker - Adjust spacing values including padding and margin - See changes applied instantly to the page - Copy the complete CSS for any edited element - Reset changes to restore original styles The live editor provides visual feedback with hover highlights and selection indicators, making it easy to identify and modify specific elements. This feature is invaluable for prototyping, testing design variations, and understanding how design tokens work together in practice. 1. JSON Export: Complete token data in structured JSON format, perfect for importing into design tools, documentation systems, or custom applications. The JSON includes all color values with RGB breakdowns, all spacing values, and complete typography information. 2. CSS Variables Export: Generates CSS custom properties (CSS variables) that can be directly integrated into your stylesheets. This format is ideal for maintaining design tokens in CSS-based design systems and ensures compatibility with modern CSS workflows. 3. TypeScript Export: Type-safe TypeScript constants that can be imported directly into TypeScript or JavaScript projects. The exported code includes proper type definitions and follows TypeScript best practices, making it easy to integrate tokens into React, Vue, Angular, or any TypeScript-based application. 4. Tailwind Config Export: Generates a complete Tailwind CSS configuration file with all extracted tokens properly formatted for Tailwind's design system. This includes color palettes, spacing scales, and typography settings, allowing you to quickly bootstrap a Tailwind project based on any website's design tokens. The extension features a clean, dark-themed interface organized into intuitive tabs: Colors Tab: Displays all extracted colors organized by type (background, text, border) with visual color swatches, hexadecimal values, and RGB values. Click any color to copy its value to your clipboard. Spacing Tab: Shows all spacing values grouped by type (margin, padding, gap) with contextual information about which elements use each spacing value. This helps identify spacing patterns and design system consistency. -Typography Tab: Presents font families, font sizes, and font weights in organized sections. Typography combinations are grouped together with text samples, showing how different type combinations appear in context. Live Editor Tab: Provides controls to enable or disable the live editing mode, with status indicators showing the current editor state. Privacy and Security Design Extractor operates entirely locally within your browser. All token extraction and processing happens on your device, with no data transmitted to external servers. The extension requires only the "activeTab" permission, meaning it can only access the current tab you're viewing, not your browsing history or other tabs. No tracking, analytics, or data collection occurs. The extension works completely offline after installation, ensuring your privacy and security. The extension uses advanced browser APIs to extract computed styles from every element on a page. It analyzes the Document Object Model (DOM) comprehensively, processing all visible and hidden elements to ensure complete token extraction. The extraction algorithm handles edge cases including transparent colors, inherited styles, and dynamically generated content. The extension is built using Manifest V3, the latest Chrome extension standard, ensuring compatibility and security.
