Replit
Cursor
Supabase
VercelIt only takes one leak.
Vibe coding lets anyone build an app. That's amazing. But AI makes small mistakes. One of them can cost you a lot.
A surprise AI bill
A leaked key lets anyone use your OpenAI account. Bills can climb into the thousands.
Customer data out in the open
Names, emails and orders that anyone can read.
Your app gets pulled
Your host or app store may take down an app that leaks data.
Trust is gone
Users who get burned don't come back. They tell their friends.
🐛 And small bugs keep breaking things until someone fixes them.
What a stranger can see
This is how it goes wrong. No hacking skills needed.
- 0:00A stranger opens your app.
Anyone can visit. Their browser downloads your app's code.
- 0:05They open the code view.
It is one right-click away. No hacking skills needed.
- 0:10They copy your key.
Now they can use your AI account or read your data. You get the bill.
- Later💸 A surprise bill. Or angry users.
Most people find out this way. VibeCheck helps you find it first.
We find it before they do
No developer needed. If you can copy and paste, you can do this.

Any app from Lovable, Bolt, v0, Replit or Cursor. No account.

Copy the fix
Each problem comes with a prompt. Paste it into your AI builder.
Your launch checklist
Every scan runs these 8 checks. Here is what goes wrong if one fails.
Every problem comes with its fix
This is what makes VibeCheck different. Each issue comes with a ready-made prompt for your AI builder. Here is one from a real-looking report.
Why it matters: Using the public key in your site, a stranger can list your users' names and emails.
In Supabase, turn on Row Level Security for the "profiles" table. Add a rule so each user can only read and edit their own profile. Then test that the app still works.
From worried to ready to launch
An example of a first scan, and a new scan after three pasted fixes.
- Customer emails are open
- OpenAI key is public
- Hidden from Google
- Customer emails are locked
- OpenAI key is hidden
- Google can find you
Example for illustration only. Not a real customer.

Will you steal my idea?
No. Here is exactly what we do, and what we don't.
We only see what's public
We look at what any visitor's browser downloads from your live app. Nothing more.
No code, no login
We never ask for your code, your repo or your password. So there is nothing to copy.
We only look. We never change
Scans are read-only. We don't sign up, fill in forms or try to break in.
We don't keep your data
If your database is open, we only note the table names. We never store or show the rows.
Your report is just a link
We don't keep a list of scans. The report lives inside its own link. Only people you send it to can see it.
Same checks every time
Our checks are automatic. They run on Vercel. No person looks at your app.
Builders on X are talking about it
Real public posts about leaked keys and open data. These people are not our customers. We are not linked to them.
bros: vibe coding is so easy bro. also bros: googling how to rotate every env variable across their vibe coded apps on a Sunday because Vercel got breached…
Every day a new vibe-coded site leaves the door open. This one was built with @Lovable… signed up. Got full blog admin access. New post, edit, delete. Everything.
Ran a security scan for a friend, on a site they vibe coded. Found their OpenAI API key hardcoded. What this means: anyone could've used their OpenAI credits and racked up a bill.
Everything works great, but sitemap + Supabase is broken. It generates an invalid sitemap that Google Search Console won't accept… Tried many prompts, wasted credits.
spent 6 hours debugging just to discover the vulnerability was architectural. vibe coding got me doing incident response on my own design decisions
your vibe-coded app isn't ready when the demo works — it's ready when the ugly paths work… auth refreshes, Supabase RLS, duplicate webhooks…

Questions, answered
Will you steal my idea?
No. We never see your code, your repo or your login. We only see what any visitor can already see on your live app. There is nothing to copy.
What is free?
The scan and the full list of problems are free. Just add your email. You see each problem and how risky it is.
What do I get for $9?
A fix report for one scan. Every problem gets a ready-made prompt. Paste it into Lovable, Bolt or Cursor and it fixes the issue.
Is it a subscription?
No. You pay once. Buy one report for $9, or get 10 reports for $29 and use them any time.
How do the 10 reports work?
You get 10 credits tied to your email. Each time you unlock a report, it uses one credit. Opening the same report again is free.
How does the JORDAN code work?
Use code JORDAN and your first fix report is free. It works on the $9 report.
Is it safe to check my app?
Yes. We only look. We never log in, fill in forms or try to break anything. Please only check apps you own or have the right to check.
What do you look at?
Your public pages and the code your site sends to every browser. We also check some settings, your site map and up to 20 links. If we find a Supabase key, we ask for one row from common tables to see if they are open. We keep only the table names.
Do you keep my results?
No. We don't keep a list of scans. Your report lives inside its own link. Only people you share it with can see it.
Do you check my code?
No. We check your live app from the outside, the way a stranger would. We don't read your source code.
Does a high score mean no one can hack me?
No. No tool can promise that. We catch the most common and most costly mistakes, so you can fix them first.

It's free. It takes 10 seconds. No sign-up.
