About

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.

About

Untitled UI is the world’s largest Figma UI kit, React component library, and icon system, offering designers and developers everything needed to design and build modern interfaces at speed. The Figma library features over 900 global styles and variables for color, typography, and effects, more than 10,000 meticulously crafted components and variants, 420 ready‑to‑use desktop and mobile page examples, and 4,600 neutral icons and logos, fully integrated into one design system. On the development side, Untitled UI React provides an open‑source collection of production‑ready components built with React v19.1, Tailwind CSS v4.1, TypeScript v5.8, and React Aria, ensuring type safety, accessibility (keyboard navigation and screen‑reader support), and lightning‑fast performance without lock‑in. AI‑ready Lovable and bolt.new kits enable instant prototyping with simple prompts, while seamless Figma previews and consistent styling across both platforms.
