Real-Time
Interact with users and know who is connected right now, across one or dozens of nodes, by using our built-in Channels and Presence technologies. Or try LiveView for a refreshing new way to develop real-time apps without the client-side complexities.
MVC without the Mess
At its core, Phoenix is a rock-solid web framework that improves the tried and true Model-View-Controller (MVC) architecture with a fresh set of functional ideas. Phoenix puts the focus on your business domain, bringing you immediate productivity and long-term code maintainability.
Versatility at your fingertips
Forget about complex messaging systems or about 3rd party tools to manage layers of cache. Phoenix uses the Erlang VM capabilities to implement its real time system and to scale out-of-the-box. This reduces operational complexity and decreases developers cognitive load.
Production ready
Phoenix accompanies you and your team from development to production. It ships with built-in instrumentation and a live dashboard that gives you insight into the Erlang VM ability to handle millions of connections alongside Elixir's tooling for building robust systems.
