pusher-js VS Centrifugo

Now let's push the notification to pusher. First you have to go to https://pusher.com/ login create an app an get API keys. Then fill them in your .env file

another tool is pusher but have a high cost https://pusher.com/

Pusher specializes in realtime WebSockets and offers a straightforward way to integrate realtime features into your React app. It's a reliable choice for apps that need to send notifications based on realtime events.

why are you considering building your own websocket service instead of using something like https://pusher.com/ ?

IVS offers chat rooms, but Kick doesn't seem to use them. All chat messages are sent over a websocket connection to Pusher. Pusher seems pretty cheap for the purpose.

Serveless Websocket service

Is it possible to use Supabase as a Pusher alternative?

if you are on time, since it is a coursework, and it is allowed to use some libraries, you can check how to use pusher it should be fairly easy for you too integrate to your application.

I've built a flutter web chat using flutter_chat_ui and dart_pusher_channels, for the backend I used soketi which is an open source node.js pusher replacement but you could just use pusher.com if you can squeeze into their free tier.

What? No. Takes 5-10 minutes to set up a websocket server manually or is just requires a few configuration variables to be set if using a hosted service like Pusher.

Hello, I am author of https://github.com/centrifugal/centrifugo. Our users can choose from WebSocket, EventSource, WebTransport (experimental stabilize in the future). WebRTC is out of scope as the main purpose is central server based real-time json/binary messaging, and WebRTC makes things much more complex since it shines for peer-to-peer and rich media communications.

What I'd like to add is that Centrifugo also supports HTTP-streaming – not mentioned by the OP – but this is a transport which has advantages over Eventsource - like possibility to send POST body on initial request from web browser (with SSE you can not), it supports binary, and with Readable Streams browser API it's widely supported by modern browsers.

Another thing I'd like to mention about Centrifugo - it supports bidirectional WebSocket fallbacks with EventSource and HTTP-streaming, and does this without sticky sessions requirement. I guess nobody else have this at this point. See https://centrifugal.dev/blog/2022/07/19/centrifugo-v4-releas.... Which solves one more practical concern. Sticky sessions is an optimization in Centrifugo case, not a requirement.

If you are interested in topic, we also have a post about WebSocket scalability - https://centrifugal.dev/blog/2020/11/12/scaling-websocket - it covers some design decisions made in Centrifugo.

Check out https://github.com/centrifugal/centrifugo - it was initially designed to be a standalone language-agnostic real-time messaging server. So it may be used with Django without radical change in the existing application and using ASGI. It can also provide a much better performance if you care about it.

It's a complete solution, including server, admin panel and client library.

We're an European company and use OVH, Hetzner and others.

Hello! Theoretically you can take a look at https://github.com/centrifugal/centrifugo - which is a standalone self-hosted real-time messaging server. It does not have native support for Laravel and not compatible with Pusher protocol, though integrating with any backend system, including Laravel: see the blog post https://centrifugal.dev/blog/2021/12/14/laravel-multi-room-chat-tutorial, also has some helper packages:

Hello, it's also possible to design an app in a way that its core will be built with Python, but WebSocket part delegated to something external and efficient like https://github.com/centrifugal/centrifugo – the benefit of the approach is that application business logic is completely decoupled from the real-time transport layer. This may lead to a scalable design with graceful degradation. I think this is especially useful when you already have backend built with Django and need to handle millions of concurrent connections.
