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, Server-Sent Events (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

Improvements

  • Option to use try lock for postgresql consumer, #988. New option for PG consumer use_try_lock (boolean, default false) to use pg_try_advisory_xact_lock instead of pg_advisory_xact_lock for locking outbox table. This may help to reduce the number of long-running transactions on PG side.

Fixes

  • Fix log entries about engine on start #992.

Miscellaneous

  • This release is built with Go 1.24.4.
  • Updated dependencies.
  • See also the corresponding Centrifugo PRO release.
