Phoenix is a full‑stack web framework for the Elixir language that enables developers to build scalable, fault‑tolerant applications. It provides built‑in support for real‑time features, API generation, and a productive development workflow.

Use cases

• Build a real‑time chat application with live updates
• Create a JSON API backend for a mobile app
• Develop an interactive HTML5 web app using LiveView
• Implement server‑side rendering with minimal JavaScript
• Scale a web service across multiple nodes with built‑in PubSub
• Rapidly prototype a web application and move to production

When to choose

• You are working in the Elixir ecosystem and need a production‑ready web framework.
• Your project requires real‑time features like live updates or websockets out of the box.
• You want a framework that emphasizes developer productivity and fault tolerance.

When to avoid

• You need a framework for a language other than Elixir.
• Your application has heavy client‑side UI requirements that rely on a JavaScript SPA framework.
• You require built‑in support for non‑HTTP protocols not covered by Phoenix.
