Centrifugo is an open-source scalable real-time messaging server. Centrifugo can instantly deliver messages to application online users connected over supported transports (WebSocket, HTTP-streaming, SSE/EventSource, GRPC, WebTransport). Centrifugo has the concept of a channel – so it's a user-facing PUB/SUB server.

Centrifugo is language-agnostic and can be used to build chat apps, live comments, multiplayer games, real-time data visualizations, collaborative tools, etc. in combination with any backend. It is well suited for modern architectures and allows decoupling the business logic from the real-time transport layer.

Several official client SDKs for browser and mobile development wrap the bidirectional protocol. In addition, Centrifugo supports a unidirectional approach for simple use cases with no SDK dependency.

For details, go to the Centrifugo documentation site.

What's changed

Centrifugo v5.4.1 comes with useful improvements and fixes.

Improvements

  • Improving delta compression – if the delta patch size exceeds the full publication payload size, the full payload will be sent now instead of the delta patch.
  • Kafka Consumer: a partition consumer buffer has been added to enhance processing efficiency, #829.
  • Support deb release for Debian 12 Bookworm #827

Fixes

  • Resolved a panic issue (panic: close of closed channel) caused by a race condition during an already subscribed error. See centrifugal/centrifuge#390. The regression was introduced in Centrifugo v5.3.2.
  • Async consumers: fix disabling consumer by using proper mapstructure and JSON tags, #828.

Miscellaneous

  • Release is built with Go 1.22.4
  • All dependencies were updated to latest versions
