AnyCable is an open-source solution designed to replace the Action Cable WebSocket server in Ruby on Rails applications, providing a more efficient and scalable architecture for real-time features. By offloading WebSocket connections to a Go-based server, AnyCable reduces the load on the Ruby application server and allows better concurrency and performance, especially under high user traffic. It integrates seamlessly with existing Rails apps, supporting the same Action Cable API while enhancing throughput and lowering latency.
AnyCable leverages Redis or other pub/sub systems for message broadcasting, enabling horizontal scaling and fault tolerance. This makes it a popular choice for developers looking to build real-time applications such as chat systems, live notifications, or interactive dashboards with improved resource utilization and responsiveness. Its compatibility with Ruby on Rails and ease of deployment make AnyCable a compelling alternative to the default Action Cable server in production environments.
