Row-Level Security policies enforce data access rules at the database level. This generator creates SELECT, INSERT, UPDATE, and DELETE policies using auth.uid() and auth.jwt() claims to automatically restrict rows based on user identity and roles, eliminating the need to write policies manually for multi-tenant or RBAC applications.

Yes. RLS policies enforce tenant isolation by evaluating auth.jwt() claims and auth.uid() during query execution, ensuring users only access rows belonging to their tenant. This generator produces tenant-isolation templates and migration scripts to apply policies across your tables consistently.

The generator produces policy templates for common scenarios, helper functions to simplify policy logic, testing queries to validate policies work as intended, migration scripts to deploy policies to your database, and documentation describing each policy's scope and security model.

This generator provides testing scenarios and queries that verify policies block unauthorized access while allowing legitimate queries. Test queries simulate different user roles and auth claims to confirm policies enforce the intended access control without breaking application queries.

While familiarity with database concepts helps, the generator abstracts policy complexity by producing ready-to-use templates and migration scripts. You define your tables, roles, and tenant model; the generator handles the SQL policy syntax and documentation.

Incomplete RLS policies can block all queries on protected tables, breaking application functionality. This generator reduces that risk by providing comprehensive policy sets, testing queries, and migration validation, helping you deploy policies that cover all expected access patterns before enabling RLS in production.
