Phoenix

Phoenix (Elixir) provides real-time scalability (millions of connections). v1.7 + LiveView allows building rich SPAs without writing JavaScript.

When to Use

• Real-Time Interactive Web Applications: Real-time dashboards, multiplayer games, and collaboration tools with LiveView.
• High-Concurrency Distributed Backends: Leveraging Erlang/Elixir BEAM VM for fault-tolerant microservices.
• Scalable WebSocket & Channel Architectures: Millions of persistent connections with minimal memory per process.
• Maintainable Functional Web Development: Clean separation with Ecto schemas, contexts, and Plugs.
