Both @fluentui/react and @headlessui/react are popular libraries in the React ecosystem. However, @fluentui/react has a larger user base and is widely adopted by Microsoft and other companies. @headlessui/react is a relatively newer library but has been gaining popularity due to its lightweight nature and focus on providing accessible and customizable UI components.

Component Collection

@fluentui/react offers a comprehensive set of ready-to-use UI components for building applications with a Fluent Design System. It covers a wide range of components like buttons, inputs, modals, and more. @headlessui/react, on the other hand, provides minimal UI components that are designed to be customizable and unstyled. It provides a foundation for building accessible and flexible UI components.

Design System Integration

@fluentui/react is tightly integrated with the Fluent Design System, which provides a cohesive and consistent visual style for applications. It follows Microsoft's design principles and offers extensive theming capabilities. @headlessui/react, on the other hand, is not tied to any specific design system and allows developers to create their own design system or integrate with existing ones.


Both libraries prioritize accessibility. However, @headlessui/react specifically focuses on providing accessible building blocks for developers to create their own accessible UI components. It emphasizes keyboard navigation, ARIA attributes, and other accessibility best practices. @fluentui/react also ensures accessibility across its components but may require additional configuration and handling for complex scenarios.

Developer Experience

Both libraries offer a good developer experience. @fluentui/react provides a rich set of features and tools, including theming support, internationalization, and a mature ecosystem. @headlessui/react, being a more lightweight library, offers simplicity and flexibility, allowing developers to have more control over the visual aspects and behavior of their components. It is also designed to be compatible with different styling solutions like CSS-in-JS or utility classes.

Community Support

@fluentui/react benefits from strong community support and has an extensive community-driven documentation. It is actively maintained by Microsoft and has a dedicated team working on its development. @headlessui/react is also well-maintained and supported by the community, but being relatively newer, it may have a smaller community and less extensive documentation.
