Centrifugo

What is Centrifugo?

Centrifugo is an open-source, language-agnostic real-time messaging server that enables developers to build interactive applications requiring instant message delivery to connected users. The server supports multiple transport protocols including WebSocket, HTTP-streaming, Server-Sent Events, GRPC, and WebTransport, providing flexibility in how applications communicate with users. The platform implements a publish-subscribe model based on channel subscriptions, allowing messages to be instantly distributed to online users. This architecture makes Centrifugo suitable for building chat applications, live comment systems, multiplayer games, real-time data visualizations, collaborative tools, and streaming metric dashboards. Centrifugo is designed to scale effectively and integrates with applications regardless of their technology stack. Being language-agnostic, it can work alongside applications built in any programming language. The server handles the complexity of real-time message delivery, allowing developers to focus on application logic rather than building custom WebSocket infrastructure. As a fully open-source project, Centrifugo offers no licensing costs and provides transparent access to its codebase. It is maintained on GitHub and backed by comprehensive documentation available on its official website, making it accessible for teams of various sizes looking to add real-time capabilities to their applications.
