Your AI built the app. Did it lock the doors?
AI coding tools ship features fast. They also ship bugs where one user can see another user's data. ApyGuard finds them by actually trying, the way an attacker would.

"It works" isn't "it's safe."
Your app passes every test you click through. But log in as a second user and change one number in the URL, and you might be looking at someone else's orders, messages, or invoices. AI assistants write this bug constantly, because nobody told them who's allowed to see what.
What we check
Can users see each other's data?
User B opens User A's profile, files, or payments.
Can a normal user act like an admin?
Deleting accounts, changing prices, opening the admin dashboard.
Can users give themselves upgrades?
One extra field in a request, and they're "premium" or "admin."

How it works
Point us at your app.
Use our Chrome extension while you click around, or our VS Code extension on your code. No docs needed.
Give us two test accounts.
We use them against each other.
Get proof, not noise.
Every finding shows exactly what User B saw that they shouldn't have.
Copy. Paste into your AI. Done.
Each finding comes with a ready-made prompt for Claude Code, Cursor, or Codex. Your AI fixes it, then you re-scan to confirm. We never touch your code.
Why not a regular scanner?
Most scanners look for broken code. These bugs live in working code: the request is valid, the response is correct, it's just going to the wrong person. Finding that takes testing logic, not pattern matching. That's what we do.
Check before your users do.
