A new PostgreSQL controller in Centrifugo OSS lets multi-node clusters run without Redis or NATS. If your application already runs PostgreSQL, the messaging plane has everything it needs — one infrastructure dependency for the whole real-time tier.
The PostgreSQL stream broker brings transactional publishing to Centrifugo's stream subscriptions. Real-time updates commit alongside the database write that triggers them — same SQL transaction, no application-side outbox, no CDC pipeline, no separate publish API call.
The PostgreSQL map broker brings durable persistence to Centrifugo-owned key-value collections and lets your application publish updates atomically inside its own database transactions — no dual-write, no application-side outbox to maintain.
A new subscription type in Centrifugo — real-time key-value collections with paginated state delivery, guaranteed convergence on reconnect, per-key TTL, conditional writes, and Fossil delta compression.
Recreating David Gerrells' 2M-particle multiplayer simulation on top of Centrifugo WebSocket protocol. The naive single channel fanout balloons each tick from 129KB to 605KB. We explore how to improve that given Centrifugo nature and good UX in mind.
Shared poll subscriptions move polling from clients to Centrifugo. Instead of 10,000 clients each hitting your backend every second, Centrifugo asks once per cycle for the union of items everyone is watching and fans the changes back out.
An interactive demo playground demonstrating what Centrifugo brings to AI token streaming — channel multiplexing, recovery, multi-tab sync, transport fallbacks, and horizontal scaling with Redis.
Centrifugo is an efficient and scalable transport for streaming AI responses. In this article, we will stream GPT-3.5 Turbo responses in real-time using Centrifugo temporary channels and Python. Simple and effective!
In this article, we create a real-time leaderboard using Centrifugo, Redis, React and Python. Here we show the usage of Centrifugo built-in asynchronous consumer from Redis Stream. The post additionally showcases Fossil delta compression and cache recovery mode.
We are excited to tell the world about Centrifugo v6 – a new major release, which is now live. This release contains fundamental changes in the configuration and adds several useful features and more observability to Centrifugo OSS and Centrifugo PRO.
While we concentrate our main efforts on Centrifugo v6 development, let's recap the most notable features and improvements introduced during Centrifugo v5 lifecycle.
In this post, we explore how WebSocket compression can optimize bandwidth costs. We also discuss strategies to minimize the CPU and memory overhead associated with the enabled WebSocket compression from the Go ecosystem perspective.
A simple yet cool example of document state synchronization on top of Centrifugal stack. The end goal is to effectively and reliably synchronize document state to application users – to avoid race condition between state load and updates coming from the real-time subscription.
This post shows the potential profit of enabling delta compression in channels and demonstrates the reduction of data transfer in various scenarios, including different Centrifugo protocol formats and using WebSocket permessage-deflate compression.
Centrifugo has GRPC subscription streams feature, in this post we show how this feature may simplify a task of delivering data to application UI in real-time. We integrate with Loki, injest log entries and stream logs to the browser based on user-supplied query
We start talking more about recently launched Centrifugo PRO. In this post, we share details about Centrifugo PRO push notification API implementation - how it works and what makes it special and practical.
In this post, the engineering team of RabbitX platform shares details about the usage of Centrifugo in their product.
In this post, we'll demonstrate how to asynchronously stream messages into Centrifugo channels from external data providers using Benthos tool. We also highlight some pitfalls which become more important in asynchronous publishing scenario.
We are excited to announce a new version of Centrifugo. It's an evolutionary step which makes Centrifugo cleaner and more intuitive to use.
This tutorial shows how to connect to Centrifugo when using Keycloak SSO flow for user authentication. Here we build a simple demo app using React and Vite.
In this post we share some details about Centrifugo Redis Engine implementation and its recent performance improvements with the help of Rueidis Go library
In this post we are discussing vaious ways developers can use to subscribe user to a personal channel in Centrifugo
Centrifugo v4 provides an optimized client protocol, modern WebSocket emulation, improved channel security, redesigned client SDK behavior, experimental HTTP/3 and WebTransport support.
In this tutorial, we are integrating Laravel framework with Centrifugo real-time messaging server to make a multi-room chat application.
In this tutorial, we are integrating Django with Centrifugo to make a basic chat application. We are using Centrifugo proxy feature to proxy WebSocket connection events to a Django backend.
In this tutorial we are integrating Centrifugo with NodeJS. We are using Centrifugo connect proxy feature to authenticate connections over standard Express.js session middleware.
Centrifugo v3 released with lots of exciting improvements
