The New York State Design System (NYSDS) is the open-source system for building New York State government websites and applications, with a component library, Figma design libraries, and design tokens built publicly and iteratively.
It's built with accessibility testing and automation baked directly into the workflow rather than as a separate manual review step, and it's developed openly and iteratively, so its GitHub history itself is a readable case study in how a state government design system evolves over time.
GovTech designers and developers building New York State (or similar US state-level) digital services who want accessible components with tokens shared across both design and code.
It's fully open source and built in public, so watching its update log directly is a useful way to see real government design decisions being made and revised.
