# Fluent UI Web

[![Build Status](https://img.shields.io/azure-devops/build/uifabric/fabricpublic/164/master?style=flat-square)](https://dev.azure.com/uifabric/fabricpublic/_build?definitionId=164) ![GitHub contributors](https://img.shields.io/github/contributors/microsoft/fluentui?style=flat-square) ![GitHub top language](https://img.shields.io/github/languages/top/microsoft/fluentui?style=flat-square) [![Twitter Follow](https://img.shields.io/twitter/follow/fluentui?logo=x&style=flat-square)](https://twitter.com/FluentUI?ref_src=twsrc%5Etfw)

> Fluent UI React is shipping its v9 final stable release. Visit the [Fluent UI React v9 Release page on the wiki](https://github.com/microsoft/fluentui/wiki/Fluent-UI-React-v9-Release) to learn more about the upcoming release schedule.

Fluent UI web represents a collection of utilities, React components, and Web Components for building web applications.

This repo is home to 3 separate projects today. Combining Fluent UI React v9 components with Fluent UI React v8 or v0 components is possible and allows gradual migration to Fluent UI v9.

The following table will help you navigate the 3 projects and understand their differences.

> Why are there two React versions? Fluent UI v8 is still widely used. We encourage you to migrate to Fluent UI v9. See the [Migration overview](https://react.fluentui.dev/?path=/docs/concepts-migration-from-v8-component-mapping--docs).

## Looking for Office UI Fabric React?

The **Office UI Fabric React** project has evolved to **Fluent UI**.

The `office-ui-fabric-react` repo is now this repo (`fluentui` in the Microsoft organization)! The name change should not disrupt any current Fabric usage, repo clones, pull requests, or issue reporting. Links should redirect to the new location. The library formerly known as `office-ui-fabric-react` is now available as `@fluentui/react` (see above table for more information).

We have a lot in store for Fluent UI - [Read our announcement here.](https://developer.microsoft.com/en-us/office/blogs/ui-fabric-is-evolving-into-fluent-ui/)

## Looking for Fluent UI React Northstar?

Fluent UI React Northstar has been superseded by Fluent UI React Components v9 and reached End Of Life in July 2025.

For more details about Fluent UI React Northstar, see its [source](https://github.com/microsoft/fluentui/tree/react-v0/packages/fluentui) and [README.md](https://github.com/microsoft/fluentui/tree/react-v0/packages/fluentui/README.md).
