syncing data instantly between a bunch of clients? like, that's a thing you can do?

hey everyone, i'm working on a project that needs real-time updates pushed to several client apps at once. like, think collaborative editing or live dashboards. we've thought about using WebSockets, but i'm trying to figure out the best patterns or architectures for handling this kind of broadcast. are there any message queue strategies, or even specific services, that are really good at sending out real-time events to lots of consumers without crashing the system or the clients? what has worked well for you all in production
