Most "design inspiration" dies in a screenshots folder. You save a site you love, then rebuild it from memory and end up with something that feels 70% right. The gap is the details — the exact greys, the type scale, the spacing rhythm — and those are the things a screenshot can't hand you.

## We read the rendered page, not the source

When you paste a URL, we load it in a real headless Chromium and read the computed styles off the live DOM — the actual rendered look and feel, after CSS, fonts, and layout have all resolved. That's very different from scraping HTML. You get the values the browser actually painted.

## What you get back

- A full color palette — primary, accent, neutral, and semantic — de-duplicated and organized.
- Typography: families, weights, sizes, and line-heights, grouped by role.
- A spacing scale and the component patterns the site leans on.
- W3C-compliant design tokens you can drop straight into a codebase.
- AI-ready prompts calibrated to the reference, for Claude, Lovable, v0, or Cursor.

The whole thing takes a few seconds on a warm run. No signup, no browser extension — just a URL and a style guide on the other side.

## How WAALEE compares to other extractors

We're not the only way to pull a design system off a page. Here's an honest map of the landscape and where WAALEE fits — cross-check any of them:

- [Dembrandt](https://www.dembrandt.com/): One-command CLI that runs a headless browser and returns real computed values. Great for terminal workflows; no prompts or accessibility check.
- [UIScanner](https://uiscanner.com/): Paste a URL, get tokens plus a build prompt. Closest in spirit to WAALEE; WAALEE adds W3C token export and a WCAG contrast pass.
- [extract-design-system](https://github.com/arvindrk/extract-design-system): Open-source CLI and Claude/Cursor skill; outputs JSON and CSS variables for local projects.
- [Design System Extractor](https://chromewebstore.google.com/detail/design-system-extractor/nnjekphemngphnhkacefcnobblojapgc): Chrome extension that reads on-page styles one page at a time. Handy for quick spot-checks.
- [WAALEE](https://waalee.ai/): Web-based, reads the rendered DOM, and hands back colors, type, spacing, W3C tokens and AI-ready prompts tuned for Claude, Lovable, v0, Cursor and Bolt — plus a WCAG check. No install.

The honest takeaway: if you live in a terminal, a CLI like [Dembrandt](https://www.dembrandt.com/) is a fine fit. If you want tokens and a builder-ready prompt from one paste in the browser, that's what we built [WAALEE](https://waalee.ai/) for.
