About Once UI

Once UI is an open source design system and component library built for Next.js (and paired with a matching design system in Figma), offering a flexible style system, 100+ ready-to-use UI components, and more than 75 copy-paste blocks to rapidly assemble web apps. It supports both simple static sites and more complex applications, thanks to pre-built, deployment-ready templates for portfolios, documentation sites, blogs, ecommerce stores, and dashboards (free and Pro versions). Once UI emphasizes “component-first” development, meaning developers don’t need to manually write utility-class-heavy styling (like with some CSS frameworks); instead, they use semantic variables and components that integrate design tokens for visual consistency. For creators used to tools like utility-class frameworks or component libraries, but who want faster development with fewer dependencies, Once UI simplifies building UIs without sacrificing design quality or accessibility.
