Hi Everyone, first of all, I apologize if this is a repeating question. We have a SaaS that we are working on and we use a custom IDP for user authentication etc. We have a requirement for implementing a proper RBAC service for the system and after some research, we found out that Zanzibar can cater to all our requirements. As there are no many stable Zanzibar open-source implementations, we are thinking of going for a managed service for our system. I haven't done a deep research on Authzed and SpiceDB. I would like to know if it is possible to use SpiceDB alone to get the requirements done or should we go for a managed Authzed plan.
