MUI is a React UI framework that provides a comprehensive suite of pre-built components and styling tools for building user interfaces. It follows Material Design guidelines and offers a wide range of customizable components, enabling developers to create visually appealing and responsive web applications efficiently.
At ProcureAI, MUI has underpinned our React frontends for user-facing applications, giving us accessible primitives, theming, and layout utilities that speed delivery while keeping the look consistent across products. We are actively migrating components to shadcn/ui for a more AI-native workflow that makes prototyping and integrating features faster with AI tools end-to-end, and will phase MUI out over the coming weeks and months. New UI work should land on shadcn/ui while existing surfaces transition incrementally.
