Phoenix is a web development framework written in the functional programming language Elixir.


Phoenix uses a server-side model–view–controller (MVC) pattern.[2] Based on the Plug library,[3] and ultimately the Cowboy Erlang framework,[4] it was developed to provide highly performant and scalable web applications. In addition to the request/response functionality provided by the underlying Cowboy server,[5] Phoenix provides soft realtime communication to external clients through WebSockets or long polling using its language agnostic channels feature.[6][7]

Two notable features of Phoenix are LiveView and HEEx. LiveView provides real-time user experiences with server-rendered HTML over HTTP and WebSocket.[8] HEEx is Phoenix's templating language which provides HTML-aware compile time checking.[9]
