🧬 VisualDNA – Extract the Design System of Any Website
VisualDNA is a developer and designer tool that analyzes any webpage and extracts its complete visual design system in seconds.
Instead of manually digging through DevTools to understand how a site is built, VisualDNA automatically detects colors, typography, UI components, layout systems, images, and technologies used on a page. The results are converted into structured data that can be used for design references, AI prompts, or code generation.
It’s built for frontend developers, designers, indie hackers, and anyone working with AI-assisted coding tools who wants to quickly understand and recreate website UIs.
🔍 What VisualDNA Can Analyze
🎨 Color Extraction
Extract full color palettes including:
• Hex and RGB values
• Usage percentages
• Automatic classification (text, background, accent, border)
🔤 Typography Analysis
Detect the typography system used on a page:
• Font families
• Font sizes and weights
• Heading hierarchy
• Type scale visualization
🧩 Component Detection
Automatically identify common UI components such as:
• Buttons and button variants
• Input fields
• Interactive elements
VisualDNA also captures the CSS properties needed to recreate them.
📐 Layout System Detection
Understand how the layout is structured:
• Flexbox and Grid detection
• Container widths
• Spacing scale patterns
• Border radius systems
• Shadow systems
🤖 AI Prompt Generator
Generate structured prompts to recreate the UI using tools like:
• ChatGPT
• Claude
• Cursor
• v0.dev
• Gemini
Prompts include design tokens, layout information, and component styles to help AI reproduce the interface accurately.
🖼️ Image Extractor
Extract all images used on a page, including:
• <img> elements
• CSS background images
• <picture> elements
Images can be previewed and downloaded individually or exported as a ZIP.
⚙️ Tech Stack Detection
Detect 30+ technologies used by a website, including:
• Frameworks (React, Vue, Next.js)
• CSS libraries and UI frameworks
• Icon libraries
• Analytics tools
• Build systems
Also includes metadata insights like Open Graph tags and PWA information.
📦 Export Developer-Ready Design Tokens
Convert the extracted design system into formats ready for development:
• JSON design tokens
• CSS custom properties
• Tailwind config
• React + TypeScript theme starter
🆓 Free Features
• Color palette extraction with usage analysis
• Typography detection and type scale
• Component and button style detection
• Layout system analysis
• AI prompt generator
• Limited prompt exports
🚀 Pro Features
• Image extractor with unlimited downloads + ZIP export
• Advanced tech stack detection
• Full export formats (JSON, CSS variables, Tailwind, React theme)
• Platform-specific AI prompts for Cursor, v0.dev, and Gemini
• Unlimited page scans
👨💻 Who It’s For
• Frontend developers studying UI patterns
• Designers collecting visual references
• Indie hackers building MVPs faster
• Developers using AI coding tools
• Anyone who wants to understand how a website’s design system works
VisualDNA helps you reverse-engineer the visual structure of any website and turn it into reusable design systems, AI prompts, and developer-ready code.
