How to extract a design system from any website
CSS Design System Extractor is a Chrome extension that extracts design tokens from any live webpage and exports CSS variables, Tailwind configuration, and Figma Variables. Extraction runs entirely in the browser. Free includes preview and basic JSON; Pro is a $29 one-time license with the full export suite. Optional AI analysis uses your own API key — we do not sell AI credits.
Steps
- Install and open a page Install from Chrome or Edge. Open a normal http/https site (browser internal pages cannot be scripted).
- Extract tokens Open the side panel → Extract Design System. Computed styles are scanned locally into a consolidated token preview.
- Export what you ship Download JSON on Free, or unlock Pro for CSS variables, Tailwind, Figma Variables, Markdown, Preview HTML, and VS Code tokens. Activate with the license key emailed after checkout.
What you get in the token pack
Colors (deduplicated), font families and sizes, spacing scale candidates, border radii, shadows, and component pattern hints. Dual light/dark sampling is available when you enable theme sampling in the panel.
Privacy in one sentence
