How it works

From worried to fixed in three steps

  1. 1

    Paste your address

    Your live app's URL, like myapp.lovable.app. No account, no code access, nothing to install.

  2. 2

    Get your grade

    We look at your app the way an attacker's browser would, and list every problem from most to least serious.

  3. 3

    Paste the fixes

    Each fix comes with a prompt you paste straight into the AI tool that built your app. Scan again to watch your grade go up.

What we check

The mistakes AI tools make most

Leaked secrets

OpenAI, Anthropic, Stripe, AWS, GitHub and Supabase service keys hiding in your JavaScript, where anyone can copy them and run up your bill.

Supabase setup

Admin keys shipped to the browser and, once you verify you own the site, which tables anyone can read without logging in.

Exposed files

Public .env files, .git folders and source maps that hand over your passwords and your code.

Security headers & HTTPS

The browser protections most AI-built apps are missing, with the exact lines to add for your host.

Questions

Good to know

Is it safe to scan my app?

Yes. We only download what any visitor's browser already downloads, plus a short list of files that should never be public. We never log in, submit forms, or change or delete anything.

Do you store my keys or data?

No. If we find a key we show only the first and last few characters, and we never store the full value. Scan results are kept for 10 minutes so repeat scans are quick.

Can I scan someone else's app?

Only scan apps you own or have permission to test. The database check only runs after you prove you own the site.

My app was built with Lovable. Will the fixes work there?

Yes. Each fix in the full report comes with a prompt written for AI coding tools, so you can paste it into Lovable, Bolt, v0, Replit, Cursor or Claude Code.

I got an A. Am I completely safe?

An A means none of the common, visible mistakes we look for. It is not a full security audit, so keep following good practice, especially around who can read and change your data.
