Extract any website's design system in one command

"The OG url extractor"

dembrandt github.com

Any url → Design system and tokens extracted from the real rendered DOM, output as W3C design tokens, DESIGN.md or Brand guide. No DevTools. No manual work.

The problem it solves

AI coding tools generate UI fast, but they have no memory of your brand. The result: misaligned tokens ship faster than ever, and nobody catches it until it's in production.

Dembrandt is the enforcement layer. It extracts what actually ships (not just what the brand guide says) and tracks drift across versions in CI.

What's built

• Core Extraction engine and it's features.
• Agentic context building & extraction mechanisms and workflows.
• MCP server & Integrations: Drops your real brand directly into Claude Code, Cursor, and Copilot.
• --design-md output: Generates a DESIGN.md file for your AI agents to read before coding.
• Agentic skills: 30 built-in AI agent skills that turn raw tokens into design system decisions.
• W3C tokens & WCAG audit: Export tokens and contrast audits computed from the rendered page.
• Dark mode & PDF export: Extracts both themes and generates a brand guide PDF in a single run.

What sponsorship funds

The CLI is MIT-licensed and free. Sponsorship covers the time required to:

• The "ESLint for design": A project-level token baseline to make Dembrandt standard infra.
• --compare & Ingest API: The first automatable path to fail a CI/CD build when brand tokens drift.
• The App platform: Snapshot history, a team drift dashboard, and alerts to Slack, Linear, and GitHub.

Who uses it

• Devs shipping UI with AI tools, who need the agent to build based on brand instead of inventing one
• Design system teams managing several apps, who need to catch drift before it ships
• Agencies auditing client sites in seconds, replacing the manual DevTools dig and the brand-guide PDF

TLDR: If Dembrandt saves your team just 2 hours of manual DevTools debugging or AI token fixing per month, any of the corporate tiers have paid for themselves.
