Lovable App Security Audit
You built a real app with Lovable, probably faster than you thought possible. Before you put real users and real payments into it, it's worth having a human check the things Lovable can't verify about its own output.
I'm Terry Threatt, a software engineer who has shipped and sold production apps on the same stack Lovable generates: Next.js/React, Supabase, and Stripe. I audit Lovable apps at a fixed price, with a report written for founders. Every finding comes with a fix prompt you paste straight back into Lovable.

Where Lovable apps consistently go wrong
Lovable is genuinely good at building working software. But it optimizes for “works in the demo,” and security problems don't show up in demos. Across AI-built apps, the same handful of issues appear again and again, and Lovable's Supabase-first architecture gives them a particular shape:
Supabase tables without row-level security.
Lovable wires your frontend directly to Supabase, which means your database rules are your security. If RLS is off, or a policy is written as USING (true), any logged-in user can read other customers' data through the API, no hacking required.
Policies that only cover reads.
A common pattern: Lovable writes a SELECT policy and forgets INSERT, UPDATE, and DELETE. Your data looks protected until someone modifies a row they shouldn't be able to touch.
Secrets in the client bundle.
Service-role keys, OpenAI keys, or Stripe secrets ending up in frontend code or misused NEXT_PUBLIC_ variables. Anyone who opens dev tools can read them, and automated scrapers hunt for exactly these.
Auth that only exists in the UI.
Hiding a button isn't access control. If a route or API endpoint isn't enforced server-side, anyone can hit it directly with a session from a free account, or no account at all.
Storage buckets that are quietly public.
User uploads (avatars, documents, exports) in buckets where anyone can fetch anyone's files by guessing URLs.
What I check in a Lovable audit
The audit is a manual, expert review built around the failure patterns above, not just an automated scan. The core of it:
The two-account test.
I create two test accounts and try to read and modify one account's data from the other, hitting your Supabase API directly rather than going through your UI. This single test finds most critical bugs in Lovable apps.
Secrets scan, including git history.
Keys that were committed once and “deleted” later are still in your repo history. I scan the full history, plus your built client bundle, for anything that shouldn't be public.
Every RLS policy, read line by line.
RLS enabled on every table, policies for every operation, actual scoping to auth.uid(), and the sneaky bypasses: views without security_invoker, SECURITY DEFINER functions, and storage bucket rules.
Server-side auth enforcement.
Protected routes and API endpoints tested directly, with no session and with the wrong session. Role checks verified server-side, not just in React state.
Billing correctness, if you charge money.
Stripe webhook signature verification, the canceled-user test (does access actually revoke?), failed-payment handling, and whether a user can check out at a price you didn't set.
The report is written for you, not for a security team
Every finding has three parts: what it is, what it costs you in plain English, and a copy-paste fix prompt written for Lovable. You paste the prompt, Lovable fixes the issue, and the report tells you how to verify the fix worked. There's a go/no-go verdict on page one, and you get seven days of included follow-up questions while you work through it.
No meetings anywhere in the process. You order, fill out a ten-minute intake form with read-only access, and the report shows up in days.
What it costs
Fixed prices, published right here, because a scared founder at 11pm shouldn't need to book a discovery call to find out what an audit costs.
| Package | Price | Turnaround | Best for |
|---|---|---|---|
| Launch Scan | $299 | 48-hour turnaround | “I just want to know if anything is on fire.” |
| Launch Audit | $999 | 5 business days | “Real users are about to trust me with their data.” |
| Launch + Revenue AuditMost popular | $1,900 | 5-7 business days | “This app is supposed to make money. Prove the pipes are connected.” |
| Ship Monitor | $149/month | Ongoing | everyone who just passed an audit and plans to keep building. |
Frequently asked questions
Is Lovable secure by default?
Lovable gives you reasonable building blocks (Supabase auth, sensible project structure), but security depends on how the generated code uses them. Generated Supabase apps very commonly ship with at least one serious issue, usually in row-level security or exposed keys. That's not a knock on Lovable; it's the nature of code that no human has reviewed.
Can't I just ask Lovable to fix its own security?
You can ask, and it will confidently say yes. But it's grading its own homework. The model that made the mistake is the model checking for it. An outside human with production experience on this stack finds the things the AI can't see about itself.
What access do you need to my Lovable app?
Read-only access only: your repo (or a zip export), the deployed URL, Supabase read access or dashboard screenshots, and permission to create two test accounts. I never take write access, and everything is deleted 30 days after the engagement.
How fast can you audit my app?
The Launch Scan turns around in 48 hours. The full Launch Audit takes 5 business days, and the Launch + Revenue Audit 5 to 7. If I find something critical early, you'll hear about it before the report.
