## What it is
Umi is an extensible, plugin-based enterprise-grade React application framework from Ant Group, built on React Router 6 with routing, build, testing, and linting out of the box. It offers dual Vite/Webpack build engines, MFSU fast bundling, SSR/SSG, and a batteries-included Umi Max distribution with antd, data flow, i18n, and micro-frontend integrations.

## Use cases
- build a production React app with routing and build tooling in one dependency
- create an enterprise admin dashboard with antd, permissions, and i18n
- scaffold a React project with conventional file-based routing
- speed up webpack builds with MFSU or switch to Vite mode
- add SSR or static site generation to a React app
- integrate micro-frontends with qiankun in a React codebase
- standardize frontend best practices across a large team

## When to choose
- you want an all-in-one React meta-framework with routing, build, test, and lint included
- you need enterprise features like i18n, access control, data flow, and micro-frontends out of the box
- your team wants locked, pre-bundled dependencies for long-term build stability
- you prefer configurable routing alongside convention-based routing
- you are building CSR-heavy apps, especially with Ant Design

## When to avoid
- you need to support IE8 or React below 16.8, or Node below 14
- you have strong requirements to customize webpack heavily yourself
- you want to pick your own router library or minimal tooling
- you primarily need server-side rendering with server loaders/actions, where Next.js or Remix fit better
- you just want a lightweight scaffold like create-react-app for a single small project
