django-rls-tenants

Database-enforced multitenancy for Django using PostgreSQL Row-Level Security. Every query -- ORM, raw SQL, dbshell -- is filtered by the database itself. Missing tenant context returns zero rows, never leaks data.

Why this library?

Existing Django multitenancy libraries enforce isolation at the application level — one missed filter and data leaks across tenants. django-rls-tenants pushes enforcement to PostgreSQL itself using Row-Level Security. Every query — ORM, raw SQL, dbshell — is filtered by the database. Missing tenant context returns zero rows, never leaked data.
