## What it is
Evergreen is Segment's open-source React UI framework and design system for building enterprise-grade web applications. It provides polished, composable components with sensible defaults, a robust theming layer, and built-in CSS-in-JS with SSR support.

## Use cases
- build a react admin dashboard with polished ui components
- design system for enterprise web apps
- react component library with theming support
- quickly prototype react ui with sensible defaults
- server-side rendered react app with css-in-js
- consistent buttons tables and alerts across a product

## When to choose
- you are building a React web product and want ready-made, enterprise-grade components out of the box
- you need a themable design system with sensible defaults and full customization when required
- you want SSR support and CSS-in-JS bundled without extra configuration

## When to avoid
- your project is not React-based
- you need highly custom, non-enterprise visual design that diverges from Evergreen's design language
- you want an unstyled headless component library
