Helsinki Design System (HDS) is the City of Helsinki’s open-source Design System, created to help teams build consistent, accessible, and user-friendly digital services across the city’s ecosystem.
What makes it stand out is how clearly it is positioned as a shared reference point for both designers and developers, not just a UI library. With guidelines, design assets, component libraries, and a strong accessibility focus, HDS feels built for the realities of public-sector digital delivery: clarity, usability, and consistency at scale.
