Centrifugo VS websocket

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.

What I can say is that if you will use Gorilla Websocket (https://github.com/gorilla/websocket) (it's archived now unfortunately, but still super robust) - then you can go to sth like 15-20kb per connection - see https://github.com/FZambia/go_websocket_memory - to achieve this you need to reduce read buffer size, reuse write buffers, use goroutine after hijacking connection (following chat example in Gorilla WebSocket repo).

No Bugs? https://github.com/gorilla/websocket/issues Even if that were true at the time of stoping development, "No bugs" is something that can never be said for any software. I really wish this community stopped recomending to use abandoned libraries if only for the potential Security issues. A not maintained Library is a very lucrative target for vulnerability hunting.

The Gorilla WebSocket License says:

We'll be using WebSocket library: "github.com/gorilla/websocket" ❣️

package github.com/gorilla/websocket is not a main package

As for Websockets, (https://github.com/gorilla/websocket) it uses ws.NextReader() to handle heavy loads of connections.

I'm looking to build a game server that uses web sockets to communicate with clients, I've looked into some of the libraries and the main ones seem to be gorilla websockets and melody.

If this is what your import looks like "github.com/gorilla/websocket" that's wrong it should be just "github.com/gorilla/websocket"
