What is a design system extractor?

A design system extractor is a tool that analyzes a webpage's CSS and returns the design tokens (colors, fonts, font sizes, border radii, shadows, spacing) it uses, structured as a reusable system. CitedRank's Clone tool clusters the raw tokens — promoting the most-used color to primary, second-tier to accents, neutrals into a scale — then exports the result as a Tailwind config, CSS variables, or JSON.

Can I legally clone someone else's design?

Use extracted designs as research, inspiration, structure analysis, or competitive benchmarking. Direct pixel-perfect copying of copyrighted designs (logos, illustrations, original photography) is not legal. Color palettes, font choices, spacing systems, and general layout patterns are not copyrightable — they're industry conventions and competitive intelligence.

What's the difference between Clone and a Chrome DevTools inspector?

DevTools lets you inspect ONE element at a time. Clone scans the ENTIRE page and aggregates: every color sorted by frequency, every font with usage count, every radius and shadow tier. The clustering + export step turns raw values into a usable system. DevTools is for debugging; Clone is for design analysis.

Can I export to Tailwind?

Yes. After running Clone, hit /api/clone/export?url=X&format=tailwind to get a `tailwind.config.js` snippet with the extracted colors, fonts, font sizes, and border radii pre-filled. Drop it into your Tailwind project, swap in your own brand assets, ship.

Does Clone capture web fonts?

We detect font families used on the page (e.g. 'Inter, Helvetica, Arial') and their usage frequency. We don't download the actual font files (that would have licensing implications). The MHTML offline archive does embed the rendered font glyphs though, so the offline copy looks pixel-perfect.

Free design system extractor

pull colors, fonts, CSS variables, and Tailwind config from any website in 15 seconds.

What this tool does

Extract any website's design system — colors, fonts, CSS — in 15 seconds.

We render the page with headless Chromium, download every external stylesheet (resolving @import chains), harvest inline <style> blocks, then cluster the raw tokens into a usable design system: primary color, accent palette, neutral scale, type scale, radius scale, shadow tiers.

Color palette extractor

Every hex / rgb / oklch value used across the site, clustered by hue, with primary + accents + neutrals automatically assigned.

Font detector

Every font family + usage count + per-weight breakdown. See the type system the page actually uses, not the one the designer planned.

Type & spacing scale

Font sizes and spacing values sorted into a scale. Catches 'we have 14 font sizes when 5 would do' on your own site too.

Radii & shadows

Every border-radius value and box-shadow tier — the secondary tokens that define brand personality.

Every CSS file captured

External stylesheets downloaded with @import resolution + inline <style> blocks. Indexed manifest with byte counts and source URLs.

MHTML offline archive

Single-file pixel-perfect snapshot including rendered web fonts. Opens in any browser.

What you get

Design tokens, ready to export to Tailwind / CSS / JSON.

Interactive design-system viewer

Click-to-copy color swatches, live-rendered font previews, type-scale visualization. Same view your designer would use in Figma.

Tailwind config export

tailwind.config.js with colors, fontFamily, fontSize, borderRadius pre-filled. Drop into your project, swap brand assets, ship.

CSS variables / JSON tokens

Same data exported as :root CSS variables or W3C-style design-token JSON. Pipe into Style Dictionary or any token transformer.

Complete ZIP bundle

HTML + CSS + screenshot + tokens + MHTML — one download. Perfect for sending to a designer or archiving a brand snapshot.

Who uses this

A design tokens extractor for designers, devs, and brand strategists.

Designers benchmarking competitors

Pull every color and font from a competitor's site in 15 seconds. Compare palettes side-by-side without screenshotting.

Developers cloning a brand

Get Tailwind config or CSS variables for any site. Skip the 2-hour DevTools dive — paste a URL, download the tokens.

Design system builders

Audit your own site to catch token drift — colors used outside your palette, fonts not in the system, radius values you forgot to standardize.

Brand strategists

Before pitching a rebrand, extract the client's current design system and the competitors' — show the gap with data.

How to use

Extract a website's design system in three steps.

No signup. No CAPTCHA. Paste the URL of the site to reverse-engineer.

1
Paste a URL of the site to reverse-engineer
Any production site works — Stripe, Linear, Vercel. CitedRank renders the page, downloads every external stylesheet, and harvests inline <style> blocks.
2
Click Run
About 12–18 seconds. Crawl4AI + the CSS pipeline extract every color, font family, font size, border radius, and shadow used on the page.
3
Export the design system
Browse the clustered palette and type scale in the Spec viewer, then download as Tailwind config, CSS variables, JSON tokens, or a complete ZIP with HTML + CSS + screenshot.

What people say

Used by UI designers, front-end devs, design system leads, and brand strategists.

“I used to open DevTools and right-click my way through 20 elements to figure out a competitor's color scheme. Now it's one paste. The cluster view (primary / accent / neutral) is exactly how I want palettes structured.”

Júlia Castro

UI designer · Design agency

“I wanted my landing page to feel like Linear / Vercel. Cloned both, exported their Tailwind configs, mashed mine together from the patterns I saw. Saved me a week of A/B testing.”

Naveen Iyer

Indie SaaS founder

“We use Clone monthly to audit our own production site. Catches color drift — when engineers ship hex values that aren't in the design system. The frequency-sorted palette makes outliers obvious.”

Lucia Bianchi

Design system lead

“Before any rebrand pitch, I extract the current site + top 3 competitors. The data tells the rebrand story 10× faster than my mood boards used to.”

Marcus Andersson

Brand strategist

“The exported merged.css is gold for forensic work. When a client says 'why is this site loading 200KB of CSS?' I show them the breakdown by stylesheet origin from the Clone manifest.”

Yumi Watanabe

Front-end consultant
