A dynamic, functional language for scalable apps
Runs on the BEAM VM: fault-tolerant, massively concurrent systems with Ruby-like syntax, the realtime backend language.
José Valim's 2011 language on the Erlang VM: Ruby-flavored syntax with telecom-grade fault tolerance. Phoenix delivers realtime web at scales that humble most stacks, LiveView removed the need for separate JS frontends in many products, and the BEAM lets one node hold millions of lightweight processes. The choice when uptime and concurrency matter more than raw CPU speed.
Who it's for
Teams building fault-tolerant, real-time systems that stay responsive under huge concurrency.
