## What it is
Phoenix is a productive, full-featured web framework for Elixir that emphasizes developer productivity and real-time features. It supports HTML apps via LiveView, JSON/GraphQL APIs, and built-in PubSub and Channels for distributed realtime communication.

## Use cases
- build a realtime web application with live updates
- create a JSON REST API in Elixir
- build interactive apps without writing JavaScript
- scaffold a full-stack web app with authentication
- build a scalable GraphQL backend
- push events to browsers across multiple nodes

## When to choose
- you want a batteries-included web framework with realtime built in
- you're building in Elixir and want proven production scalability
- you need server-rendered interactive UIs via LiveView
- you need distributed PubSub across clustered nodes

## When to avoid
- your team doesn't know Elixir and can't invest in learning it
- you need a huge ecosystem of JavaScript frontend libraries
- you're building a simple static site
- you need a framework in a more commonly hired-for language
