While I always marveled at how Hubs survived the 2020 layoffs (which included the people working on WebVR/WebXR at the time), seeing it shutting down is a shame. We used it to run monthly meetups for the WebXR Discord for just about the last 3 years. Very curious what's going to happen to it now, whether it gets handed off to another entity (i.e. Firefox Reality to Igalia) or left to the community somehow.

Is it open source? If so, could it be realistically hosted somewhere else?

Yes, both the Hubs client and related backend services (Reticulum, Dialog, etc) are all open source, but it's somewhat difficult to stand up manually. There's Hubs Community Edition which launched late last year that lets you spin up everything necessary in a Kubernetes cluster, which is what I've been working on getting set up on a small Hetzner VPS.
