WebSockets vs. Server-Sent-Events vs. Long-Polling vs. WebRTC vs. WebTransport
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.
- Centrifugo v5.1.0 released, with new powers for real-time messaging tasks, now with proxy GRPC subscription streams – similar to WebSocketd but over the network

Integrating websockets into my current app
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.

Laravel Websockets vs Soketi vs Laravel Echo Server
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:

Is Python a good option to implement Websockets?
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.
- Centrifugo – real-time messaging server (WebSocket, etc.) which scales well and integrates with any backend. SDKs for browser and mobile development included

I'm open-sourcing my game engine
They use (uWebSockets)[https://github.com/uNetworking/uWebSockets], which was written in C++, but has an interface to use in NodeJS. It's been really performant for me in my simple tests compared to other popular websocket libs that slow down fairly quickly.

What's the hot tech stack these days?
Websockets are also pretty valuable for updating the page in real time, there are servers in many languages. I'm a big fan of https://github.com/uNetworking/uWebSockets which is C++ but also has JS bindings to use with Node.js.

Nuklear – A single-header ANSI C immediate mode cross-platform GUI library
Not exaclty -- it looks like it's pretty overkill for my needs
I'm looking for something more like websocketpp[0], or even just grpc without a requisite proxy. uWebsockets looks really promising, being header only, but in the fine print requires a runtime library. unfortunately, none of that ecosystem seems to use cmake, making integrating it that much more of a pain.
why use cpp for this, I'm sure some HNer will ask. the ray tracer itself is using cuda, that's why. I've also debated
- running it as a grpc server and having some proxy in a more web-accessible language
- creating python bindings and using python to make a websocket/http server for it
neither of those are out of the question, but they're not my first choices, because I'd like to keep the build & execution simple. introducing dependencies, especially other executables, is in conflict with that.
i don't need anything particularly scalable -- a threaded implementation, or one using select() would be fine, if not preferable.

WebSocket Server in C
Really cool i also made and CAPI for using WebSocket in C, https://github.com/uNetworking/uWebSockets/tree/master/capi

Socketify.py - Maybe the fastest web framework for Python and PyPy
We discover a really fast, small, and well maintained C++ Library called uNetworking/uWebSockets, but no C API available, so we create and adapt the full C API from uNetworking/uWebSockets and will integrate libuv powered fetch and file IO, this same C API is used by Bun
- In the 1970s, programming was an elite's task. Today programming is done by uneducated "farmers" and as a result, the care for smart algorithms, memory usage, CPU-time usage and the like has dwindled in comparison.
