Awesome DESIGN.md

A curated collection of 54 DESIGN.md files extracted from real, developer-focused websites. Each file is a complete design system specification that AI agents can read to generate pixel-perfect, brand-consistent UI.

What is DESIGN.md?

DESIGN.md is a concept introduced by Google Stitch — a plain-text design system document that AI agents read to generate consistent UI. It's just a markdown file. Drop it into your project root and any AI coding agent instantly understands how your UI should look.

How to Use

1. User says "make it look like [brand]" → Find the matching reference file below
2. Read the reference file from references/{site-name}.md
3. Copy the DESIGN.md content into the user's project root as DESIGN.md
4. Use the design tokens (colors, typography, spacing, components) when generating UI code

What Each DESIGN.md Contains

Every file follows the Google Stitch DESIGN.md format with 9 sections:

1. Visual Theme & Atmosphere — Mood, density, design philosophy
2. Color Palette & Roles — Semantic name + hex + functional role
3. Typography Rules — Font families, full hierarchy table
4. Component Stylings — Buttons, cards, inputs, navigation with states
5. Layout Principles — Spacing scale, grid, whitespace philosophy
6. Depth & Elevation — Shadow system, surface hierarchy
7. Do's and Don'ts — Design guardrails and anti-patterns
8. Responsive Behavior — Breakpoints, touch targets, collapsing strategy
9. Agent Prompt Guide — Quick color reference, ready-to-use prompts

Workflow

1. User specifies a brand → Direct match

User: "Build me a landing page that looks like Stripe"
→ Read references/stripe.md
→ Copy content to user's project as DESIGN.md
→ Use the design tokens to generate UI code

2. User wants to browse → Filter and suggest

User: "Show me dark-themed design systems"
→ Suggest: Vercel, Cursor, ElevenLabs, Resend, Warp, Supabase, etc.
→ Let user pick, then load that reference

3. User doesn't specify a style → Smart recommendation

When the user asks to build a UI without mentioning any brand or style preference (e.g., "帮我做一个落地页", "写一个 dashboard", "做一个 SaaS 官网"), proactively recommend 3–5 design systems based on the project type:

Project Type	Recommended Styles	Why
SaaS 官网 / Landing page	Stripe, Vercel, Linear	经典高转化 SaaS 风格，简洁专业
开发者工具 / 技术产品	Vercel, Cursor, Raycast, Supabase	暗色系、代码友好、极客气质
AI 产品 / Chat UI	Claude, Mistral AI, ElevenLabs	AI 原生设计语言，温暖或未来感
Fintech / 金融产品	Stripe, Revolut, Coinbase	信任感、精密感、数据密集
效率工具 / 生产力产品	Notion, Linear, Superhuman	极简、信息密度高、键盘优先
电商 / 消费品牌	Airbnb, Apple, Spotify	视觉驱动、大图、情感化设计
内部后台 / Dashboard	Sentry, PostHog, ClickHouse	数据密集型、暗色仪表盘
创意 / 设计工具	Figma, Framer, Clay	大胆配色、动感十足
企业级 / B2B	IBM, HashiCorp, MongoDB	稳重、结构化、Design System 成熟

Recommendation workflow:

User: "帮我做一个 AI 聊天产品的界面"
→ Agent: "推荐以下设计风格供你选择：
   1. 🟠 Claude — 温暖柔和的赤陶色调，编辑式布局，适合对话产品
   2. 🟣 Mistral AI — 法式工程极简，紫色调，优雅专业
   3. 🎬 ElevenLabs — 暗色电影感，波形美学，适合音频/多模态
   4. ⬛ Vercel — 黑白精准，极致简约
   5. 🟢 VoltAgent — 终端风格，翠绿高亮，适合技术型 AI
   选一个编号，我直接用对应的设计系统帮你生成。"
→ User picks one → Load reference → Generate UI

If the user says "随便" or "你决定":

• Default to Vercel (safest all-rounder: clean, modern, professional)
• Mention the choice and offer to switch: "我先用 Vercel 风格（简约黑白），不喜欢随时换。"
