Awesome Design Systems is a curated directory of publicly available design systems from companies, organizations, and open-source projects around the world. A design system is a set of shared standards, guidelines, and reusable components that a product team uses to build consistent user interfaces. Well-known examples include Google's Material Design, Apple's Human Interface Guidelines, and Atlassian's design system. This repository is simply a comprehensive, organized list, not code itself. It catalogs hundreds of design systems with tags indicating what each one includes: coded UI components (actual ready-to-use interface elements), voice and tone guidelines (how to write copy and communicate with users), designer files (Sketch, Figma, or Photoshop templates for visual designers), and links to source code when available. The list spans entries from large tech companies (Adobe, Alibaba, Amazon, Apple) to airlines, governments, media companies, and small startups. Each entry links to the official documentation or website for that design system. A designer, front-end developer, or product manager would use this as a research reference, for example, when building a new design system for their own organization and wanting to study how others have approached it, or when looking for an existing open-source design system to adopt. It is a pure reference resource, containing no programming language of its own.
