Untitled UI is a commercial design system that combines a large Figma UI kit, a React component library, and an icon set into a single ecosystem for designing and building modern interfaces. The homepage presents it as “the world’s largest Figma UI kit and React component library,” highlighting over 900 global styles and variables, 10,000+ components and variants, 420+ page examples, and 2,000+ icons and logos. Untitled UI Figma focuses on production-ready layouts using Auto Layout 5.0, smart variants, and WCAG-aware typography and color, with multiple kit versions (PRO Variables, PRO Styles, and PRO Lite) so teams can choose between a variables-driven workflow or a simpler styles-based setup, all with dark mode support built in. 

Alongside the Figma kit, Untitled UI React offers an accompanying library of open-source React components built with React Aria and styled with Tailwind CSS, positioned for teams who want consistent handoff between design and code. The site also promotes Untitled UI Icons, free and paid icon sets, example projects, documentation, and a free starter version of the Figma kit, all under a lifetime-updates model once purchased. Testimonials, usage stats, and badges from platforms like Product Hunt and Gumroad frame it as a widely adopted starting point for product teams, agencies, and individual designers who want to standardize their interface foundations and accelerate project delivery without rebuilding common components from scratch.
