Web Frameworks & Servers

Phoenix is the flagship web framework for Elixir — productive like Rails, but with real-time and concurrency built into its DNA. Under the hood, Plug provides composable middleware and Bandit or Cowboy serve HTTP. For resource-oriented applications, Ash Framework generates APIs and admin UIs from declarative schemas.
