Practical RBAC for multi-tenant SaaS
A defense-in-depth pattern: row-level security, JWT scopes, audit logs, and the five traps we still see in 2026.
Authorization is the part of the codebase that quietly grows until it isn't quiet anymore. We've audited enough multi-tenant SaaS apps to know the same five mistakes keep showing up — and we have a default architecture that prevents them.
We cover role modeling, JWT scopes, row-level security at the database layer, audit logging that actually answers who-did-what, and the UI patterns that make it impossible to ship a button that shouldn't exist. If you're building B2B SaaS, this is the RBAC layer we wish every codebase shipped with.
