I have a multiplayer web game also on SvelteKit but I created my own little sockets server with Go and Redis streams running on a tiny k8s cluster. I'm curious how much traffic you're getting and how much it costs to run it.

Fluid Framework looks interesting. Since it's open source you can either use a cloud service (Azure Fluid Relay) or run it on Kubernetes with Routerlicious. https://fluidframework.com/
