The Death of Manual CSS Inspection
You’ve been there: you find a site with a perfect typography scale or a layout that flows flawlessly across devices. You open Chrome DevTools and spend the next forty minutes hunting through nested divs, trying to figure out if that padding is a hardcoded value or a CSS variable. By the time you’ve mapped out the color palette and the grid system, your creative momentum is dead.
Most "design pickers" are toys. They give you a list of hex codes and maybe a font name, then leave you to do the heavy lifting of actually building the system. This tool changes that by treating the live DOM as a structured database rather than just a collection of pixels. It doesn't just look at the site; it reads the architectural intent behind it.
What is design extract Extract any website s complete design system with one comman?
design extract Extract any website s complete design system with one comman is a developer tool CLI and MCP server that crawls websites to extract design tokens, layout patterns, and interaction states into code-ready formats — unlike basic color pickers, it captures the underlying architecture including responsive breakpoints and WCAG accessibility scores. Built by Manav Arya, it targets developers who need to bridge the gap between a live reference site and a functional codebase instantly.
Whether you are trying to sync a legacy site to a new design system documentation or you want to feed a precise style guide to an AI agent like Claude, this tool automates the extraction of the "boring" parts of frontend development.
Hands-on Experience: 10 Seconds to a Full System
Beyond Simple Color Swatches
When I first ran this tool against a complex SaaS landing page, I expected the usual list of colors. Instead, I got a structured breakdown of the layout system. It identified the flexbox patterns, the specific gap values used in grids, and the container widths across four different breakpoints. This is where the tool justifies its existence. Most scrapers fail the moment a media query triggers; this one programmatically resized its headless browser to capture how the design adapts. It actually tells you why a site looks good on mobile, not just what color the buttons are.
The AI Agent Workflow (MCP Integration)
The standout feature in my testing was the Model Context Protocol (MCP) server. If you use Cursor or Claude Code, you know the frustration of trying to explain a visual style to an LLM. By running this tool as an MCP server, I could simply tell Claude, "Look at this URL and update my local components to match their spacing and border-radius logic." The tool provides a -mcp.json file that serves as a direct bridge. It eliminates the "hallucination" factor where AI tries to guess CSS values; instead, it hands the AI the exact computed styles from the source.
The "Clone" and "Apply" Commands
I tested the clone command, which attempts to scaffold a Next.js application based on the extracted data. It’s not a magic "steal this website" button—you won't get a perfect pixel-for-pixel replica of complex logic—but it does give you a functional repository with the tailwind.config.js and globals.css already populated with the target's design tokens. For rapid prototyping, this saves at least two hours of boilerplate setup. The apply command is equally impressive, as it auto-detects if you are using shadcn/ui or plain Tailwind and writes the tokens directly into your existing configuration files without overwriting your custom logic.
Interaction State Capture
One detail I haven't seen elsewhere is the automated interaction capture. The tool programmatically hovers and focuses on elements to record state changes. If a button has a specific transition-timing-function or a subtle shadow shift on hover, it’s included in the 19-section markdown report. This level of detail is critical if you're trying to replicate the feel* of a premium UI, not just the static look. During my design extract Extract any website s complete design system with one comman review, this was the feature that felt most like "cheating" in a professional workflow.
Getting Started with designlang
To use this tool, you need Node.js (v20 or higher) and a basic comfort level with the terminal. There is no GUI; this is built for developers who want speed over buttons.
- Installation: Run
npm install -g designlangto get the CLI globally. - The Big Bang Command: Run
designlang extract https://example.com. This will launch a headless Playwright browser, crawl the site, and dump 8 files into a local folder. - Framework Specifics: If you want mobile-ready tokens, use the flag
--platforms ios,android,flutter. - AI Integration: To use it with your AI editor, run
designlang mcpand add the resulting JSON to your Cursor or Claude settings.
--auth flag if you need to extract styles from behind a login screen. You can pass your session cookies directly to the tool so it can see your dashboard designs.
Pricing Breakdown
The pricing for this tool is straightforward because it is currently an open-source project. However, the value it provides rivals paid enterprise "design-to-code" platforms.
| Tier | Price | What You Get |
|---|---|---|
| OSS Version | $0 (MIT License) | Full CLI access, MCP server, all 8 output formats, and unlimited extractions. |
| Self-Hosted | Free | You run the compute; you keep the data. No usage limits. |
| Commercial Use | Free | The MIT license allows you to use this for client work or internal company tools. |
Pricing is not publicly listed for any "Pro" or cloud-hosted version — visit the official repository for current plans or to contribute to the project.
Strengths vs Limitations
While this tool offers unprecedented depth for a CLI utility, it is designed for a specific technical audience. It excels at technical accuracy but requires a developer's mindset to navigate the raw data it produces.
| Strengths | Limitations |
|---|---|
| Native MCP server for seamless AI agent integration. | No GUI; requires terminal and Node.js proficiency. |
| Captures dynamic hover and focus interaction states. | Struggles with sites built entirely on HTML5 Canvas. |
| Direct export to Tailwind v4 and shadcn/ui formats. | Generated code may require manual cleanup on obfuscated sites. |
| Completely open-source and free for commercial use. | Requires local compute power for headless browser crawling. |
Competitive Analysis
The market is split between simple browser extensions and heavy enterprise design-to-code platforms. This tool carves a niche by focusing on the "developer experience" and AI-assisted workflows rather than just visual inspection or pixel-perfect cloning.

FAQ
Does it work on websites behind a login screen? Yes, by using the --auth flag, you can pass session cookies to the headless browser to extract styles from private dashboards.
Can I export the data into Figma? The tool generates a structured JSON token file that can be imported into Figma using plugins like Tokens Studio or Figma’s native variables.
Is extracting a design system legal? This tool extracts public CSS and architectural tokens; however, you must ensure your use of the resulting styles complies with the original site's copyright and terms of service.
