> Free Supabase Row Level Security scanner. Real HTTP probes, automatic Fix SQL, Supabase SQL Editor deeplink, no signup.

## What OhMyPolicy is

OhMyPolicy is a free web tool at https://ohmypolicy.com that audits a Supabase project for exposed tables and missing Row Level Security (RLS) policies. The audit runs in roughly 10 seconds for typical projects and returns a tokenized report URL valid for 72 hours.

## What problem it solves

In a typical Supabase architecture the browser talks directly to PostgreSQL via PostgREST using the public anon key. Without correctly configured Row Level Security policies, any table that PostgREST exposes is readable — and often writable — by anyone on the internet. This is the single most common cause of Supabase data leaks. Supabase does not enable RLS by default when you create a table in the public schema, which makes silent exposure easy.

## How the scan works (step by step)

1. The user submits three values from the Supabase dashboard Settings → API page: the project URL, the service_role key, and the anon key.
2. The Cloudflare Worker fetches the OpenAPI definition from the project's REST endpoint using the service_role key. This is used only to enumerate table names and columns and is not stored.
3. For each table, the Worker issues HEAD and GET requests using the anon key against the PostgREST endpoint, and parses the HTTP status and row count to classify READ exposure.
4. For each table, the Worker issues a probe POST request with a benign payload to classify WRITE exposure. The request is rolled back via constraint violation; no data is written.
5. Storage buckets are probed for unauthenticated listing.
6. A Mermaid ERD is generated from the schema for visual review.
7. Every exposed table is paired with a Fix SQL snippet — ALTER TABLE ... ENABLE ROW LEVEL SECURITY followed by a starter CREATE POLICY — and a Supabase SQL Editor deeplink that pre-fills the SQL in the user's project.

## Pricing and access

The scanner is free with no signup. Reports persist for 72 hours under a random unguessable token. Paid features such as scheduled re-scans, user-perspective simulation, deeper linting, and team workflows are on the roadmap.

## Roadmap

OhMyPolicy is positioned as a multi-platform policy scanner. The supported platforms are planned to expand:

- 2026 Q3 (target): Firebase Security Rules and Firestore REST exposure scanning.
- 2026 Q4 (target): Clerk permissions audit.
- 2027: General PostgreSQL RLS validation for Neon, AWS RDS, and self-hosted Postgres.

## Frequently asked questions

### What is Supabase RLS?
Row Level Security is a PostgreSQL feature (available since 9.5) that filters rows at the database layer based on the current authenticated user. In Supabase it is the primary access control because clients talk to Postgres directly through PostgREST.

### Is it safe to share the service_role key?
The service_role key is used only to read schema metadata during the scan. It is not logged, not persisted, and not included in the scan report. Users who prefer the strongest posture can rotate the key in the Supabase dashboard immediately after the scan.

### How long does a scan take?
Roughly 10 seconds for projects under 40 tables. Larger projects take proportionally longer; warnings are shown for projects over the threshold.

### What output do I get?
A report URL with: a list of exposed tables, per-table Fix SQL, a Supabase SQL Editor deeplink for one-click application, storage bucket exposure flags, and a Mermaid ERD of the schema.

### Does OhMyPolicy support Firebase or general Postgres?
Not yet. Supabase is the first supported platform; Firebase Security Rules, Clerk permissions, and general PostgreSQL RLS validation are on the 2026 roadmap.

### Is OhMyPolicy affiliated with Supabase?
No. OhMyPolicy is an independent developer tool. Supabase trademarks and brand assets belong to Supabase Inc.
