Is my vibe-coded app safe?
A vibe-coded app is safe only if someone checked the parts the AI left to you: the database rules and the keys. By default those two are the most likely to be wrong, and both are visible from your public URL, so you can know for sure in about a minute instead of guessing.
You cannot assume it is safe
The app running smoothly tells you nothing about whether it is secure. Security problems do not break the app. They sit quietly until someone goes looking, and the people who go looking run automated tools that check thousands of sites a day. A vibe-coded app that looks finished is exactly the kind they find things in.
The app running smoothly tells you nothing about whether it is secure.
Two things decide the answer
- Can anyone read your database? If Supabase row-level security is off, or Firebase rules are open, the public key in your app reads every row. This is the most common and most damaging issue.
- Did a secret key ship to the browser? A service-role or live payment key in your JavaScript hands full access to anyone who opens dev tools.
Get those two right and you have closed the openings that matter most in a vibe-coded app.
How to know for sure
Scan your live URL. Plaintext reads the shipped JavaScript, the public endpoints, and the database rules the same way an attacker would, and tells you plainly whether your data is reachable. A clean scan means nothing was found in what was tested.
Frequently asked
How do I know if my vibe-coded app is safe?
Scan your live URL with a passive scanner. It reads what the browser receives and reports exposed keys, an open database, and missing protections. That tells you the real state of the deployed app, not what the code was meant to do.
What is the biggest risk in a vibe-coded app?
An open database. If row-level security is off, the public key that ships in every vibe-coded app can read your whole table, exposing all your user data to anyone who opens the app.
Check your own app in about a minute. Paste your URL and Plaintext reads the shipped JavaScript, the public endpoints, and the database rules for the exact holes vibe coding tools leave open. The first scan is free.
