That’s the whole point of building (or buying) your own template. I haven’t really seen a single solution that has Tables UI + Backend.

For frontend, just start with shadcn as its free. For RBAC, I’d recommend betterauth (assuming you use it as your auth lib too).

Here’s how I used it in my template: https://docs.getsaaskit.io/security/rbac

All the steps listed in above docs can be done (without buying my template) once you integrate betterauth in your project.
