What you can build

  • Build an internal incident room where a backend publishes status changes and responders receive updates through channel subscriptions.
  • Add live comment delivery to a document review tool while keeping comment storage and permissions in your application backend.
  • Stream job-state changes from a backend into an operator interface, with channel history and recovery for reconnecting clients.
  • Publish stock-change events to subscribed storefront clients so they can update availability without polling.
  • Relay incremental response updates from an application backend to connected clients, while retaining model calls and conversation storage in your own application.

Try this prompt

Build a small end-to-end live incident update workflow using Centrifugo: a backend endpoint accepts a status update, publishes it to a channel, and a client subscribes and renders updates. Keep incident records and authorization in the application’s existing data layer; do not treat message delivery as durable storage. Include configuration notes, reconnect behavior, and a local development setup based on the official quickstart.

Get started

  1. Install and configure

    Choose a binary, package, or Docker setup using the official installation instructions. Review production configuration before exposing the server.

  2. Connect a client

    Follow the official quickstart to connect a client SDK and configure the server and application backend for a first channel.

  3. Add publishing and storage

    Have your backend publish through Centrifugo’s HTTP or gRPC API. Consult the documentation for authentication and, when needed, Redis, PostgreSQL, or NATS scaling.

License & notes

Apache-2.0Apache-2.0 licensed; commercial use is permitted subject to license notices and other obligations. Hosting and compute are your responsibility. Scaling may require Redis, PostgreSQL, or NATS infrastructure, which can have separate costs. No model or paid API is required by the documented core workflow; prices depend on your hosting and storage choices.

  • Centrifugo delivers real-time messages; application business logic, durable records, and authorization policy still need to be designed in the surrounding application.
  • Production deployment requires hosting and operational configuration; scaling can add Redis, PostgreSQL, or NATS infrastructure and its associated costs.
  • Apache-2.0 permits commercial use; redistribution requires compliance with license and attribution conditions.
