Apps built with Lovable, Bolt, Replit, Cursor, and similar tools ship fast. That's the point. But fast-shipped apps share a predictable set of gaps — and most of those gaps are invisible until a real user triggers them. This guide covers the most common ones.
Probably not, if you haven't specifically checked. That's not an insult — it's structural. AI code generators optimize for making things work in the happy path. They scaffold a login flow that logs in. They create a database schema that stores data. They wire up a payment form that charges a card.
What they don't do well: configure the security boundaries, think about what happens when something fails, or worry about what happens when your third user opens the app at the same time as your first two.
The risks aren't theoretical. They are specific, common, and fixable — if you know they're there.
Ordered by how often we find them in free audits, not by severity.
Supabase enables RLS per table, but it defaults to off. AI-generated code often creates the tables and skips the policies. The result: any authenticated user can read every row in your database.
If a secret key is referenced in a React component or anywhere in your frontend code, it ships to the browser. Every visitor can extract it from devtools. This includes Stripe keys, OpenAI keys, and internal service credentials.
Password reset, magic link, and sign-up endpoints with no rate limit are trivially brute-forced or used to spam your users. Most AI-generated auth scaffolding does not include rate limiting by default.
Supabase storage buckets are public by default. User-uploaded files — profile photos, documents, receipts — are accessible to anyone with the URL unless the bucket is explicitly set to private with signed URLs.
AI code generators create tables and queries but rarely create indexes. A query that returns instantly with 100 rows will time out at 10,000. You will not see this problem until you have real users.
If your payment webhook does not verify the Stripe-Signature header, anyone can POST fake payment events to your endpoint and unlock paid features or corrupt your order data.
A single unhandled promise rejection can crash the entire React tree, showing a blank screen to your user. AI-generated apps rarely include error boundaries at the route level.
Work through this before you share your app publicly. Items marked critical are the ones we see cause actual incidents.

The most reliable approach is to have someone who didn't build the app look at it with a specific checklist and real tools — not just a mental model of what “should” be there.
That's what the free audit is. Submit your deployed URL and a few qualifying questions. Shane reviews the app with AI-assisted scanning and human judgment, then sends back a written report with specific findings — not generic advice.
If everything looks fine, you'll know it looks fine. If something is wrong, you'll know exactly what and why.
Five questions. Written report within 48 hours. Personally reviewed by Shane Jordan. Free, no obligation.
