Supabase Row-Level Security Policy Tester and Debugger
Developers using Supabase rely on PostgreSQL row-level security (RLS) policies for data access control but have no way to test or debug them without deploying and manually verifying. A wrong RLS policy can expose data or block legitimate access. An RLS testing tool that simulates queries as different user roles, visualizes policy evaluation, and catches data exposure risks before deployment prevents security incidents.
Problem Statement
A developer sets up an RLS policy on a users table: 'Users can only see their own data.' They test with their own account and it works. But the policy has a subtle bug: when a user's role is null (like during anonymous access), the policy evaluates permissively and exposes all user data. This bug is invisible during normal testing because the developer always has a role set. It goes undetected for months until a security researcher discovers it. The developer had no tool to simulate null-role access or visualize how the policy would evaluate under different conditions.
The Idea
A Supabase RLS testing tool that simulates database queries as different user roles, visualizes policy evaluation paths, and detects data exposure risks before policies go live.
Why Now
Supabase's 2024-2025 growth has brought many frontend developers to PostgreSQL who are unfamiliar with RLS. The combination of powerful security primitives and developer inexperience creates a high-risk gap. Several high-profile Supabase data exposure incidents in 2024 were traced to misconfigured RLS policies. The shift toward edge functions and client-side database access makes RLS the last line of defense.
