• Using Clerk, quite unhappy with it. No proper RBAC... — Using Clerk, quite unhappy with it. No proper RBAC (roles are tied to organizations, not stored on user itself, so you cannot have a concept of global admin or something like that, unless you use metadata for storing arbitrary key value paris), and more than once in the past weeks/months it had a downtime causing the whole app to fail. ...
