Supabase SaaS architecture
A Supabase SaaS boilerplate with the tenant boundary enforced
Boilerplate-Stack uses Supabase for more than sign-in. Auth identities, personal accounts, workspaces, memberships and Postgres Row Level Security form one data boundary that every account-scoped feature can reuse.
Use Supabase as the application foundation
- Magic link, OTP and OAuth authentication flows
- Personal accounts and multi-user workspaces
- Dynamic roles, invitations and permission checks
- Postgres RLS, explicit Data API grants and storage policies
Security lives below the component layer
Membership is the source of tenant access
A membership connects a user, an account and a role. Queries and mutations resolve that relationship before returning account data, allowing the same user to hold different permissions in different workspaces.
Row Level Security backs application checks
Account-scoped tables carry policies that verify membership inside Postgres. Server authorization remains explicit, while RLS provides the database boundary if a client attempts to query outside the current tenant.
Fresh projects reproduce the intended grants
Migrations define schema, policies, functions and explicit anon, authenticated and service-role grants. Local reset and disposable QA flows exercise the same boundary before changes reach a hosted project.
Supabase capabilities already connected
- Auth callback, onboarding and session-aware server utilities
- Workspace invitations, roles and account switching
- Storage-backed CMS media and RAG documents
- pgTAP and browser personas for cross-tenant access tests
Keep Supabase speed without guessing the security model
Start from explicit account boundaries, policies and migrations, then add the data that belongs to your product.
