About Fluent UI
Overview
Fluent UI is Microsoft's official front-end framework for building experiences that fit into Microsoft 365. It delivers a shared library of UI components, design tokens, and guidance so applications look and behave consistently with Microsoft's own products.
The framework is open source and developed in the open on GitHub, and it continues to evolve through the Fluent 2 design language. Microsoft engineering teams use it across the company's web products, and external developers adopt the same components, themes, and accessibility features for their own applications.
Key Benefits
- Open-source React component library maintained by Microsoft
- Design tokens and theming that support light and dark modes
- Keyboard navigation and screen-reader support built into components
- Design language shared with Microsoft 365 products
- Regular releases and an active contributor community on GitHub
How It Works
Developers install the Fluent UI packages into a React project and compose interfaces from pre-built components such as buttons, inputs, dialogs, and data grids. Design tokens drive theming, so applications inherit the Microsoft design language without hand-written CSS for every control.
Use Cases
- React developers building enterprise web applications
- Product teams creating add-ins and experiences that fit into Microsoft 365
- Design system teams distributing a shared component library across an organization
- Accessibility-focused teams that need keyboard and screen-reader support out of the box
Why Choose This Product
Fluent UI ships the same components Microsoft uses to build its own experiences, so teams get a design language that is actively invested in and already proven at scale. Because it is open source, developers can inspect the code, contribute fixes, and keep the library aligned with their needs.
