The problem

AI wrote your code. Who checked it?

Not a scare story — three documented cases. Bots crawl new sites within hours of them going live, and they look for exactly this.

apps exposed by one flaw

CVE-2025-48757: row-level security left off, so anyone could read other people’s records.

Names, emails and API keys readable by any visitor — no login, no exploit needed.

How it works

Three steps, one minute

1
Paste your link
No signup, no access to your code or hosting. Just the address anyone can open.
2
We look, we don’t touch
A real browser loads your app like a visitor: console, network, rendered page, speed.
3
Get the fix, not a lecture
Each finding comes with proof and a prompt you can paste straight back into your builder.

What you get

A real report, not a checklist

This is an actual scan of a demo app — grade, findings in plain words, and the measurements behind them.

out of 100

Critical: 1
High: 1
Medium: 2
Passed: 14

Critical

A full-access key reached the browser

Anyone opening your page can read and change every row in your database.

High

Any website can read your API responses

Your API allows requests from any origin, so another site can pull your data through a visitor.

Medium

Your app throws errors in the visitor’s browser

Part of the page silently stops working — the visitor sees an empty screen, you see nothing.

Fix prompt · paste into Lovable, Bolt or CursorCopy

Move the service key out of the client bundle.
Keep it server-side only, expose a narrow API
instead, and rotate the leaked key.

Not only security

A full check-up, like at the doctor

Security is the heart, but we check everything a visitor and a search engine meet — 30 checks across eight areas, one run.

Leaks

Keys and tokens that reached the browser or the repository

Access

Whether one user can reach another user’s records

Runtime

Errors thrown at visitors, broken images, failed requests

Speed

Core Web Vitals measured on a throttled connection

Search

Whether Google can index you and has something to show

Delivery

Compression, caching, certificate and its expiry

Dependencies

Libraries with publicly known vulnerabilities

Data storage

Publicly readable tables and open file storage

Is this safe?

We are a very attentive visitor

Fair question — we are asking you to hand a link to a tool you just met. So here is exactly what happens.

We do not break inNo logging in, no password guessing, no load testing. We read what your app returns to anyone.
Your data is not storedThe page, the bundles and the traffic live in memory for the length of the scan. What is saved is counts and a masked sample.
We never sell lists of vulnerable sitesYour results are private by default. That is the whole business — not a side channel.
We say what we cannot seeFrom the outside we do not see logic errors inside your code. The report lists what was skipped and why.

Sixty seconds to knowing

Your app is public right now. Check it before someone else does.
