The server offers robust features including flexible authentication, various subscription types, channel history, online presence, delta updates, and the ability to proxy connection events to a backend. It supports out-of-the-box scalability through integrations with efficient brokers like Redis (and compatible storages) and Nats. Centrifugo is battle-tested, having been used in production for a decade by numerous companies. A PRO version is also available, offering advanced features like analytics with ClickHouse, real-time tracing, performance optimizations, push notification API, and SSO integrations for corporate and enterprise environments.
