Supabase Security Audit
Is Your Supabase Database Exposed?
In roughly 30% of Supabase apps I've reviewed, it takes less than a minute for automated tools to download all proprietary data and turn a normal user into an admin — taking over the entire app. If your app was built with AI tools like Replit, Lovable, or Bolt, your database is almost certainly at risk.
How the Free Audit Works
Enter your app's URL and the audit does the rest. Ownership is verified automatically to prevent misuse — then it scans your Supabase backend as a logged-out visitor, just like an attacker would.
Enter Your App URL & Verify Ownership
Paste your website URL. The audit automatically verifies that you own the app before scanning — this protects you and prevents bad actors from using the tool against others.
Supabase Detection
The audit scans your website to find the Supabase project URL and API keys embedded in your app — the same way an attacker would discover them.
Logged-Out Access Testing
The audit probes every table, tests write permissions, and checks Row Level Security policies — all as an unauthenticated visitor. It finds what data is readable, writable, or downloadable without logging in.
Storage Exposure
The audit scans your Supabase storage buckets for public access misconfigurations — uploaded files, documents, and media that may be downloadable by anyone.
Get Your AI-Ready Fix Prompt
You receive the exact text prompt to paste into your AI tool — Cursor, Replit, Lovable, or whatever you used to build the app. Your AI applies the security fixes for you.
Need More Than the Free Scan?
The free audit shows what's exposed from the outside. The paid deep audit logs in and tests what authenticated users can really do.
Logged-In Privilege Escalation
I log in as a regular user and test whether they can make themselves an admin, access other users' data, or take over the entire application.
Business Logic Bypass
Can a user add premium subscription options without paying? Skip payment flows? Access features they haven't purchased? I test every shortcut an attacker would try.
SQL Remediation Scripts
You don't just get a report — you get ready-to-run SQL scripts that fix your RLS policies, tighten permissions, and close every gap I find.
Scaling & Architecture Review
Is your database ready for growth? I review indexing, query performance, connection pooling, and architecture to ensure your Supabase setup scales with your product.
