VisualDNA – Design System Extractor

About

🧬 VisualDNA – Extract the Design System of Any Website

VisualDNA is a powerful developer and designer tool that analyzes any webpage and extracts its complete visual design system in seconds.

Instead of manually inspecting elements in DevTools, VisualDNA automatically detects colors, typography, UI components, layout systems, images, and technologies used on a site. The results are converted into structured data you can use for design references, AI prompts, or code generation.

Perfect for frontend developers, designers, indie hackers, and AI-assisted “vibe coding” workflows.

🔍 What VisualDNA Can Analyze
🎨 Color Extraction

Extract complete color palettes with:
• Hex and RGB values
• Usage percentages
• Automatic classification (text, background, accent, border)

🔤 Typography Analysis

Detect the full typography system used on a page:

• Font families
• Font sizes and weights
• Heading hierarchies
• Complete type scale visualization

🧩 Component Detection

Automatically identify UI components such as:

• Button styles and variants
• Input fields
• Interactive elements

VisualDNA also extracts exact CSS properties so components can be recreated instantly.

📐 Layout System Detection

Understand how a layout is built:

• Flexbox and Grid detection
• Container widths
• Spacing scale patterns
• Border radius systems
• Shadow systems

🤖 AI Prompt Generator

Generate AI-ready prompts to recreate the UI using tools like:

• ChatGPT
• Claude
• Cursor
• v0.dev
• Gemini

Prompts are structured to help AI tools reproduce layouts, colors, and components accurately.

🖼️ Image Extractor

Extract all images used on a webpage, including:

• <img> elements
• CSS background images
• <picture> elements

View images in a lightbox and download them individually or as a ZIP file.

⚙️ Tech Stack Detection

Automatically detect 30+ technologies used by a website, including:

• Frameworks (React, Vue, Next.js)
• CSS libraries and UI frameworks
• Icon sets
• Analytics tools
• Build systems

Also includes metadata insights such as Open Graph tags and PWA information.
