Real-time for your applications, hosted in France
🔒 VPS onlyA scalable real-time messaging server powered by Centrifugo, installed and maintained by DINAO. WebSocket, SSE, PUB/SUB — a sovereign alternative to Pusher and Ably, on your French servers.
What is Centrifugo?
Centrifugo is an open-source and scalable real-time messaging server, designed to be language-agnostic. It allows you to easily add real-time features to any application: chat, live comments, multiplayer games, live data visualizations, collaborative tools, or AI response streaming.
It relies on a channel-oriented PUB/SUB model: your backend publishes messages to channels via a simple HTTP or GRPC API, while clients subscribe using the official SDKs. Several transports are supported — WebSocket, HTTP-streaming, Server-Sent Events, GRPC, WebTransport — and SDKs are available for JavaScript, Dart/Flutter, Swift, Java, Python, Go, and .NET.
Centrifugo positions itself as a self-hosted alternative to Pusher, Ably, PubNub, socket.io, or SignalR. It scales across multiple nodes thanks to efficient brokers like Redis, PostgreSQL, or NATS, following the project's motto: "configure it once, for good".
