Sveltos

Sveltos is an open-source Kubernetes add-on manager built for teams running GitOps across multiple clusters — it handles the messy work of sync'ing and managing add-ons so you don't have to do it manually on every cluster. The real pain point here is multi-cluster management getting out of hand at scale, and this seems to address that directly by letting you declare your add-on desired state once and letting Sveltos do the propagating. It's niche but if you're dealing with cluster sprawl, this is probably less painful than the alternative.
