A curated collection of 55 DESIGN.md files inspired by popular developer-focused and consumer websites. DESIGN.md is a plain-text markdown format introduced by Google Stitch that AI coding agents can read to generate consistent, pixel-accurate UI. Each file captures visual theme, color palette, typography, component styles, layout principles, and responsive behavior for sites like Vercel, Stripe, Notion, Apple, and many more. Drop a file into your project root and instruct your AI agent to build matching UI without needing Figma exports or JSON schemas.
