Built for builders.
Design.md Store is a curated marketplace for DESIGN.md files — structured design system specifications in a single Markdown file that AI coding assistants like Claude, Cursor, and GitHub Copilot can read directly as project context.
Every file in the library is formatted to the open DESIGN.md specification published by Google Labs (Apache 2.0 license). Each file combines a YAML front matter block of exact design tokens — colors, typography, spacing, border radius, component properties — with a human-readable Markdown body that explains the design rationale. AI tools use both layers to generate consistent, on-brand UI code.
The library covers 30+ design systems across fintech, tech, retail, food and beverage, gaming, and media. Files are available free to download — no credit card required.

Frequently asked questions
What problem does Design.md Store solve?
Without a design spec, AI tools produce arbitrary colors, inconsistent typography, and components with no coherent system. Design.md Store provides ready-made DESIGN.md files so you can give your AI tools exact design context — instantly, without writing a spec from scratch.
Who is Design.md Store for?
Built for developers and engineers who use AI coding assistants — Claude, Cursor, GitHub Copilot, v0 — to build UIs. Instead of prompting an AI repeatedly to match a visual style, drop a DESIGN.md file into your project and the AI follows it automatically.
What AI tools are compatible?
DESIGN.md files work with Claude Code (reads from project root automatically), Cursor (via @DESIGN.md reference), GitHub Copilot (as system prompt context), and Google Stitch (native import). Any AI tool that accepts document context can use a DESIGN.md file.
Are these official design system files?
No. The files are independently created design system implementations inspired by publicly visible production design systems. They are not official files from Stripe, Apple, Coinbase, or any other brand. Each file is formatted to the open DESIGN.md specification and documented as an inspired implementation.
Who created the DESIGN.md format?
The DESIGN.md format was created by Google Labsand published under the Apache 2.0 open-source license. Design.md Store is an independent marketplace built on top of this open format — we didn't invent the spec, we built the best place to find ready-to-use files for it.
Is Design.md Store free?
Yes. The free tier gives you access to 30+ curated design system files — no credit card required. Sign in with GitHub or email and download immediately. A Pro subscription unlocks additional premium files and features.
How do I add a DESIGN.md file to my project?
Download the file and place it in the root of your project — same level as package.json. Claude Code picks it up automatically. For Cursor, reference it with @DESIGN.md in your prompt. For any other AI tool, paste the file contents as system context before generating UI code.
