    THE FULL CHECK

    Connect GitHub. We read your code so you don’t have to.

    The problems that hurt AI-built apps most live in the code and the database rules, where a website check can’t look. Connect a repository and get a plain-English report with a fix for each one.

    • Secret keys saved in your code

      Keys and passwords committed to your repository, including ones deleted since but still in its history.

    • Who can read and change each table

      Database rules that leave customer data open to anyone who finds your app.

    • Packages with known security holes

      Add-ons your AI tool installed that have published vulnerabilities.

    • Pages and routes that skip the login check

      Places where someone could get in without signing in first.

    HOW IT WORKS

    From "is this safe?" to fixed, in three steps.

    Want a quick look first? Paste your website address at the top of the page. It takes about a minute and needs no account.

    1. 01

      Connect GitHub

      Create a free account and connect GitHub with read-only access. You pick the repositories. We can’t change your code.

    2. 02

      We scan your code like an attacker would

      We read it for the mistakes AI tools commonly make: leaked secret keys, open database tables, risky packages and pages that skip the login check.

    3. 03

      Fix it with a copy-paste prompt

      Each issue comes with what it means, why it matters, and a fix prompt you paste into your AI tool. Then check again.

      FAQ

      Questions, answered.

      Still unsure? Talk to us.

      Do I need to know how to code?

      No. Every issue is explained in plain English, and each one comes with a fix you can paste straight into Lovable, Bolt, Replit, Cursor or Claude Code.

      What can you see when I connect GitHub?

      Only the repositories you choose, and only to read them. We can't change your code, push commits, or see repositories you didn't pick. You can remove access at any time from your GitHub settings.

      What's the difference between a quick check and a full check?

      A quick check looks at your live website from the outside, the way an attacker would. A full check also reads your code on GitHub, so it can find leaked secrets, risky packages and database rules that aren't visible from the outside.

      Is the quick check really free?

      Yes. You can run a quick check without an account or a card. Create a free account to see every issue and how to fix it.

      How long does a check take?

      A quick check usually takes about a minute. A full GitHub check takes a few minutes, depending on the size of your project.

      Will a check break or slow down my app?

      No. We only look. We don't change anything on your site or in your code, and we don't send heavy traffic.

      What if I can't fix an issue myself?

      Share your report with a vetted developer through LetMeCheck and they'll fix it for you.

      Know your app is safe before your users find out it isn't.
