Pixel-accurate token extraction
Computed colors, fonts, spacing & shadows — what actually ships, not what the stylesheet claims.
New · v1.0 — built for AI coding agents
Compile any website into anAI-readydesign system.
DesignDNA is a Chrome extension that extracts colors, typography, spacing and components from any live site — and ships a structured Markdown spec straight to Cursor, Windsurf, Cline and Claude Code.

Why DesignDNA
Stop describing
designs to AI. Hand it the spec.
Most design-to-code tools dump a screenshot and pray. DesignDNA reads the DOM the way a senior engineer would — capturing the system, not just the surface — so your agent writes code that already matches your brand.
Component-aware structure
Detects buttons, cards, inputs and nav patterns — emits semantic specs your agent can scaffold instantly.
Markdown LLMs love
Dense, hierarchical output tuned for context windows. Cursor & Claude Code parse it with zero prompt engineering.
04Versioning
Drift-proof contracts with hash + timestamp
Re-run anytime to diff your design system against the live source of truth. Catch regressions before they reach production.
One sweep. Every token.
How it scans
DesignDNA sweeps the live DOM like a radar — locking onto typography, color, spacing, shadows and components in a single pass.

How it works
Three clicks from any URL to a production-grade spec.
- Step 0101
Visit any website
Open the page whose design language you want to capture — a competitor, an inspiration board, your own production app.
- Step 0202
Click the DesignDNA icon
The compiler walks the DOM, samples computed styles, clusters tokens and identifies recurring component patterns in seconds.
- Step 0303
Paste into your agent
Copy the Markdown or download the file. Hand it to Cursor, Windsurf or Claude Code as system context — and start building.

$ "Build a pricing page using the attached design system."
→ Generating ProductCard, PricingTier, FeatureRow…
→ Using brand:#635BFF · radius:12px · font:Sohne
→ 11 files written. On-brand. Ready to ship.Compiled Linear's design system in 30 seconds and dropped the spec into Cursor. My agent finally stopped inventing random shades of purple. Game changer.

We use the JSON export to seed our Tailwind config straight from production. Onboarding a new agent to our brand now takes one prompt instead of ten.
Cloned a competitor's landing page into a working Claude Code project in under a minute. The token extraction is shockingly accurate.
