Is my Lovable, Bolt or Cursor app safe to launch?

Why AI-built apps fail in the same places

AI coding tools write the feature you asked for. They rarely write the guard around it unless you ask. The result works perfectly in a demo and is wide open in production. Security reviewers who look at many of these apps report the same short list of problems again and again, and one 2026 study of 200 deployed Lovable and Claude Code apps reported at least one vulnerability in 91% of them.

The five checks

1. Can one user read another user's data? Most of these apps use Supabase or a similar database that the browser talks to directly. If row level security is off, or the rules are too loose, anyone with your public key can read every row. Test it: make two accounts and try to load the second account's records while logged in as the first.

2. Are secret keys in the browser? Open your live site, open the browser's developer tools, and search the loaded JavaScript for "sk_", "service_role" and "secret". Payment, email and admin keys must live only on the server.

3. Does the server check permissions on every action? Hiding a button is not security. Copy a request from the developer tools network tab, change the record ID, and send it again. If it works, anyone can do it.

4. Are payments and webhooks verified? If you use Stripe, check that your webhook handler verifies Stripe's signature, and that what a customer gets comes from the server, never from a price the browser sends.

5. Can someone abuse it? Look for sign-up, login, password reset and any AI feature that costs you money per use. Without rate limits, one script can create thousands of accounts or run up your AI bill overnight.

When to pay for a human review

Do the five checks yourself first. Pay for a review when:

• any check failed and you are not sure the fix is complete,
• the app stores customer data, health or money information,
• you take payments, or
• you are about to show it to investors, a large customer, or a developer you plan to hire.

Automated scanners are a good first pass and cheap. They miss the business-logic problems in checks 1 and 3, which is where the worst leaks come from.

What NexAI's review covers

The AI app audit is a human review of what you shipped: the access rules, secrets, permission checks, payments and abuse limits above, plus whether it will hold up with real users. I review what shipped, write the plan that makes it safe, and either hand you the plan or take it to production myself. It is from $500: $500 working session · $1,500 to $2,500 full 6-pass repo audit · $4,500 to $8,000 hardening sprint. Turnaround: written audit report within 24 hours. Start with the free app readiness checklist if you want to work through it yourself.
