awesome-design-md: A curation that teaches AI the actual design language of websites with a single DESIGN.md file

This repository collects design system documents extracted from real websites, based on the DESIGN.md concept proposed by Google Stitch. This Markdown file defines visual rules such as colors, typography, and layout patterns in text, allowing AI coding agents to read them and generate consistent UIs.

Simply place a single Markdown file in the project root—no Figma exports or complex JSON schemas required. Since it is the format LLMs understand best, no separate parsing or configuration is needed. If AGENTS.md defines 'how to build,' DESIGN.md dictates 'how it should look.'

It includes analysis of diverse styles, from global companies like Apple, Stripe, and Linear to 1990s retro web design. Each entry goes beyond simple color codes to provide in-depth analysis of actual design intent and patterns, helping generate high-quality UIs that transcend superficial imitation.

Useful for developers struggling to maintain design consistency when rapidly prototyping with Vibe Coding, or designers who want AI to learn a specific brand's design language. Released under the MIT License, it can be freely used in commercial projects.
