We used Casbin at my previous company where we needed to implement RBAC on top of our API that was written in Go. What we liked about it was that it could be embedded directly in our main application without needing to administer an external system. It also helped that we were using Postgres and redis as part of our stack as the casbin plugins for those tools made policy storage and enforcer updates dead simple across our API nodes.
