For a multi-tenant SaaS product, how well do backend platforms handle role-based access control and row-level security?

“Supabase uses PostgreSQL Row Level Security, which is particularly well suited to multi-tenant applications.”

“You can enforce tenant isolation directly in PostgreSQL.”

“- Fine-grained permissions.”

“- Supports complex relationships.”

“Supabase is particularly attractive because authorization and data access are integrated into the same database.”

“- RLS policies can become complicated.”

“- Complex authorization can affect query performance.”

“- You need to understand PostgreSQL security concepts.”

“- Service-role credentials can bypass RLS, so server-side access needs careful handling.”

“Firebase takes a different approach.”

“- Role-based access.”

“- Tenant-aware security rules.”

“- Custom claims.”

“More sophisticated organization membership and relational permission models can become cumbersome.”

“One important limitation: custom claims and membership data need careful management, particularly when users belong to multiple organizations or change roles frequently.”

“- Built-in team memberships.”

“- Multiple roles per team member.”

“- Resource-level permissions.”

“- Relatively straightforward implementation.”

“- Less flexible than writing arbitrary PostgreSQL authorization policies.”

“- Complex cross-organization relationships may require additional application logic.”

“- Resource permissions need careful architectural planning.”

“- Row-level filtering.”

“- Column-level permissions.”

“- Dynamic user and organization attributes.”

“My assessment: Hasura is particularly compelling if your SaaS product has a GraphQL architecture and sophisticated data-access requirements.”
