Manually inspecting CSS or using Source Design

Ever look at a site and wish you could instantly steal their design system? Stop inspecting elements manually. Source Design extracts colors, spacing, and shadows into ready-to-use Tailwind v4 themes or a DESIGN.md file. Speed up your workflow: source--design.vercel.app

Stop manually inspecting elements to copy hex codes and font stacks. Source Design extracts the entire design system—colors, spacing, and shadows—from any live URL. One click gets you a Tailwind v4 theme and DESIGN.md. No more guesswork: source--design.vercel.app

Stop digging through DevTools to find a site's hex codes. Paste any URL into Source Design and get a full Tailwind v4 theme + DESIGN.md in seconds. Reverse-engineering design systems just became a one-click job. Source: source--design.vercel.app

AI coding is only as good as the context you provide. With our new SKILL.md, you can teach any LLM to reverse-engineer live CSS into structured W3C design tokens and spacing scales, bridging the gap between a live website and your local codebase.

The live web is now your design system library. Use Source Design to turn live CSS into documented DESIGN.md files and W3C design tokens, bridging the gap between visual inspection and implementation.

Reverse-engineering top-tier UI just got easier. Source Design features a library of 22+ pre-extracted websites like ChatGPT, Supabase, Porsche and more. Export typography, shadows, and colors directly into your dev workflow without the manual documentation.

Manual CSS inspection is a bottleneck for frontend workflows. With Source Design’s new CLI and MCP, you can extract design tokens directly into your terminal or through your AI agent, turning any website's live CSS into a structured DESIGN.md in seconds.

Manual CSS inspection is a productivity killer. Source Design lets you paste any URL and instantly get a structured DESIGN.md and Tailwind v4 theme. It’s the fastest way to bridge the gap between live sites and your development environment.

Tired of manually inspecting CSS to reverse-engineer a design system? We built a tool that extracts live styles from any website and converts them directly into Design.md file, W3C tokens, Tailwind v4, and CSS variables. Speed up your frontend workflow: source--design.vercel.app
