Design Systems Library for AI Coding — Abdallah Issa

71 open-source DESIGN.md files for AI coding agents like Cursor, Claude Code, and Lovable. Colors, typography, and spacing for brands like Airbnb, Apple, and Stripe.

An open-source library of design systems in DESIGN.md format, ready to use with AI coding tools.

The library contains 71 design systems extracted from well-known brands including Airbnb, Apple, Stripe, Vercel, and Linear.

Each DESIGN.md file includes: the full colour palette with values, typography and type scale, the spacing system, and border radius and shadow values.

Usage: drop the file into your project and point Cursor, Claude Code, or Lovable at it, and the agent builds the UI in that brand identity instead of inventing arbitrary colours.

All files are free and open, with a step-by-step guide page covering how to use them with each tool.
