AI App Builders
Is Your Lovable App Secure Enough to Launch? A Checklist

Probably not yet, if nobody has checked it. An app built with Lovable, Bolt, Emergent or Cursor usually works well enough to demo, but the same gaps keep showing up: secret keys in the browser, open database rules, and no limits on who can call what. You can test most of them yourself in an afternoon with the checklist below.
Why is everyone talking about this now?
On 14 and 15 October, attackers got into Zeabur, a hosting platform that deploys apps straight from GitHub. BleepingComputer reports that over 3.2 million environment-variable records and data for 321,810 accounts were exposed. Zeabur is now shutting down, pausing apps on its shared clusters from 1 December. Its own explanation: internal credentials stored in plaintext, and admin tokens that never expired.
The same week, Lovable's 16 October update lets Enterprise admins block publishing while an app has unresolved personal-data findings.
Neither story means AI builders are unsafe. They show that data leaks in the last step to production, the part the builder doesn't do for you.
What usually goes wrong in an AI-built app?
A prototype is built to work, not to survive a stranger poking at it. The usual gaps:
- Secret keys in front-end code. Payment, OpenAI or email keys end up in JavaScript any visitor can download, so anyone can run up your bill.
- Open database rules. Lovable and Bolt projects often sit on Supabase, which is safe when Row Level Security is on and every table has a policy. When it's off, one user can read another's records.
- Checks that only happen in the browser. Hiding the "Admin" button isn't access control. The server has to refuse the request.
- Keys that never change. Zeabur's admin tokens hadn't been rotated since January 2024. A key pasted into chats and tool settings for months has probably travelled.
- Accounts that aren't yours. If the database, hosting and domain sit under a freelancer's login and that platform closes, you migrate on someone else's deadline.
The pre-launch checklist
| Check | How to test it yourself | Fix |
|---|---|---|
| No secrets in the browser | On your live app, press F12 and search the Sources tab for "sk_", "key" and "secret" | Move that call to the server, then rotate the key |
| Database rules on | In Supabase, look for tables marked unrestricted or with RLS disabled | Enable RLS and add a policy per table |
| Users can't see each other's data | Make two test accounts. Logged in as A, open a URL that belongs to B | Filter by the logged-in user on the server |
| Admin pages protected | Log in as a normal user and type the admin URL | Check the role on the server for every admin action |
| Payments confirmed properly | Abandon a Razorpay or Stripe payment halfway. Is it marked paid? | Mark orders paid only from a verified webhook |
| Limits on login and AI calls | Press "Send OTP" or your AI feature 50 times in a row | Rate-limit per user and per IP |
| Keys rotated | List every key and when it was created | Issue new keys, revoke the old ones |
| Backups exist | If the database vanished tonight, what would you restore? | Daily backups, and test one restore |
| You own the accounts | Whose email owns the domain, hosting, database and repo? | Move them to a company email you control |
| Privacy basics | Is there a privacy notice and a way to delete someone's data? | Add both, and ask for consent where needed |
In India, that last row is about to matter more. Most DPDP Rules duties for businesses, including breach notification, come into force on 13 May 2027. An app you launch now will still be live then.
I host on Zeabur. What should I do today?
Treat every value stored there as leaked. Create new database passwords, API keys and cloud keys, then revoke the old ones at each provider, because a new key doesn't cancel the old one. Move to hosting under your own account well before 1 December.
Do I need to rebuild the app?
Usually not. Most fixes change how the app talks to its database and which code runs on the server. The screens and flows you built in Lovable can stay.
A rebuild makes sense only when the data model can't support the product, say every record sits in one table with no owner, and you already have paying users. Even then it's often just the backend and database that needs redoing. If two or three checklist rows fail, it's a focused fix. If most fail, treat it as one production launch project, not a string of patches.
Get a second pair of eyes before launch
Our AI-built app to production service starts with a short review of your code, data model and integrations. We tell you plainly what's solid and what needs fixing, then give you a fixed-price quote before any work starts. The code, domain and hosting end up in your name.
Send us your project link and we'll reply within 4 working hours.
