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
