Clone Any Website in 5 Minutes
Not code generation — design specification generation. AI automatically deconstructs any website's colors, typography, spacing, and animations into structured DESIGN.md docs. Paste into Cursor or Copilot to replicate.
Open Any Webpage
Open the website you want to analyze in Chrome. Supports all public HTTPS pages.
One-Click Analysis
Click the extension icon to auto-collect CSS variables, font families, colors, gradients, shadows, and animation parameters.

Why Is Replicating a Website So Hard?
Manual extraction is time-consuming and error-prone; AI code tools lack design semantics
How to copy colors?
Manual color picking requires checking every element one by one, easily missing gradients, transparency overlays, and CSS variable hierarchies.
How to copy fonts?
Font stacks, weights, line heights, and letter spacing are scattered across dozens of CSS rules — finding them in DevTools is like searching for a needle in a haystack.
How to copy spacing?
Margin, padding, grid gap, and container max-width form a system. Manually measuring one page takes 1-3 hours.
How to copy animations?
Transition duration, easing curves, hover states, and micro-interactions are buried in deep CSS and JS — nearly impossible to replicate accurately by eye.
Not Code Generation — Design Specification Generation
Do you need a reusable design system, or a one-time code dump?
There are already many "website cloning" tools, but their outputs and use cases differ fundamentally from Design Extractor. Choose based on your real needs:
| Dimension | same.new | v0.dev | Open-Lovable | Design Extractor |
|---|---|---|---|---|
| Core Output | React code | React code | React code | DESIGN.md spec |
| Usage | Online platform | Online platform | Self-hosted | Chrome extension |
| Barrier | Medium | Low | High (deployment) | Extremely low |
| China Access | VPN required | VPN required | VPN required | Direct access |
| Design Semantics | None | Partial | None | Full spec |
| Reusability | Hard (coupled) | Medium | Medium | Very easy |
| Pricing | Paid | Free tier | Open source | Free (BYO key) |
If you need "runnable code immediately" → choose same.new or v0.dev. If you need "to understand and reuse a design system" → choose Design Extractor.

Different Roles, Same Tool
Whether you are a developer, designer, or product manager, design spec extraction boosts your workflow
Frontend Developers
Paste DESIGN.md directly into Cursor, GitHub Copilot. The AI generates code matching the target style based on precise specs — no more vague "make it feel like that" requests.
UI / UX Designers
Batch-deconstruct competitor websites to build a design trend library. Compare color schemes, typography systems, and component specs side by side for professional competitive analysis reports.
Product Managers
Communicate design intent to teams with objective data, not vague "reference Airbnb." Pixel-level specifications reduce communication cost between design and development.
Frequently Asked Questions
Cloning is for learning and understanding design principles, leading to new original designs. Copying is directly replicating someone's design for commercial use without substantial changes. Cloning is an essential part of designer growth — almost all top designers have extensively cloned masterworks to understand their design decisions.
Design Extractor analyzes and generates design specs in just 30 seconds. But "cloning" is a complete workflow: understand the specs → implement with AI tools or manually → adjust details. With precise DESIGN.md, the implementation phase shrinks from hours to 5 minutes.
same.new and v0.dev output runnable React code for rapid prototyping; Design Extractor outputs structured design specification documents (DESIGN.md) for understanding design systems, cross-comparison, and long-term reuse. They complement each other: extract specs first, then generate code.
It includes overall atmosphere description, core style definition, complete color palette (with CSS variables), font stack specs, texture system (gradients/shadows/blur), motion design specs, component specs (buttons/cards/navigation/inputs), and a cloning guide.
The Free tier is completely free with unlimited usage — just bind your own OpenAI-compatible API Key (Kimi, GPT-4o, DeepSeek, etc.). Pro ($5/mo, 50 analyses) and Max ($20/mo, 200 analyses) provide platform quota without API Key configuration.
All publicly accessible HTTPS webpages are supported: corporate sites, SaaS product pages, ecommerce, blogs, portfolios, etc. For pages with extensive custom fonts or complex WebGL effects, extraction may need manual supplementation.
Absolutely. Paste the DESIGN.md into Cursor, GitHub Copilot, Windsurf, or Claude Code. The AI generates code matching the target style based on precise specs — far more accurate than vague descriptions like "make it like Linear."
No. Design Extractor is a Chrome browser extension — install it, click the icon, and analyze. The generated DESIGN.md is plain Markdown that non-technical users can read, containing colors, fonts, and spacing in an understandable format.
