Just chiming in here to say how great of a product ArgoCD is. We've been using it for a few years now and it makes for a highly configurable deployment management layer on top of our clusters. Highly recommend it for managing multiple application deployments where things like RBAC, observability, and configurability matter. Also doesn't hurt that it has a decent UX (although we primarily interface via automatons these days). The project maintainers are also extremely responsive and professional (thanks @alexmt!).

All that being said, Cuber definitely feels like a different sort of market fit.
