    STEP 1 · THE FREE AUDIT

    Ten checks on what anyone can see from the outside.

    AI builders get you to a working app fast. They don’t always lock it down, make it findable or keep it quick. The audit covers the visible gaps in about a minute.

    Security4 CHECKS

    What a stranger can see and copy from your live site.

    • HTTPS and SSL

      Is your site served over a valid, current certificate, so visitors and their data are encrypted?

      What is HTTPS?

    • Exposed secret keys

      Looks through the code your site sends to browsers for API keys and tokens anyone could copy and use on your account.

      API key exposure

    • Security headers

      Checks that your site tells browsers to switch on the protections that make common attacks harder.

      Security headers

    • Source code exposed

      Checks whether files that should stay private, like .env files, are publicly reachable.

      Exposed .env files

    SEO4 CHECKS

    Whether Google can find, read and show your pages properly.

    • Can Google see your content

      Do your pages contain real text before JavaScript runs? Many AI-built apps show search engines a blank page.

    • Title, description and social preview

      Checks the title, description and share image people see in search results and when your link is posted.

    • Builder leftovers

      Spots default titles, placeholder text and other signs your site still looks like the builder’s template.

    • Real 404 pages

      Does a page that doesn’t exist return a true “not found”, instead of a blank page Google may index?

    AI visibility1 CHECK

    Whether AI assistants are allowed to read your site.

    • AI crawlers allowed

      Checks that the crawlers behind tools like ChatGPT, Claude and Perplexity aren’t blocked from reading your pages.

    Performance1 CHECK

    How fast the site feels on a phone.

    • Mobile speed

      How quickly your site loads on a phone, so visitors don’t give up before they see anything.

    STEP 2 · THE FULL CHECK

    The audit checks your site. LetMeCheck checks your code.

    The problems that hurt AI-built apps most live inside the code and the database rules, where no website audit can look. Connect GitHub and we read the code for you.

    • 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.

    FAQ

    Website audit questions, answered.

    Still unsure? Talk to us.

    What does the free website audit check?

    Ten things across four areas: security (HTTPS, exposed secret keys, security headers and exposed source files), SEO (whether Google can see your content, your title and social preview, builder leftovers and real 404 pages), AI visibility (whether AI crawlers are allowed) and mobile speed.

    Do I need to sign up to run it?

    No. Paste your address and the audit runs straight away, with no account and no card. Create a free account afterwards if you want to unlock the full report and the fix for every issue.

    Is it safe to run on my live site?

    Yes. The audit only looks, the way any visitor or search engine would. It doesn’t log in, change anything or send heavy traffic.

    Which websites can I check?

    Any website that anyone on the internet can open, whether you built it with Lovable, Bolt, Replit, Cursor, Claude Code or by hand. Pages that sit behind a login can’t be checked from the outside.

    How long does it take?

    About a minute. You can watch each check finish as it goes.

    What do I do if it finds problems?

    Each result is explained in plain English with a prompt you can paste into your AI tool to fix it. If you’d rather not do it yourself, a vetted developer can fix it for you.

    What does the full GitHub check find that the audit can’t?

    Secret keys saved in your code or its history, who can read and change each table in your database, add-on packages with known security holes, and pages or routes that skip the login check. These live inside your code, so no website audit can see them.

    Is it safe to connect my GitHub?

    Access is read-only and limited to the repositories you choose. We can’t change your code or push commits, and you can remove access at any time in GitHub → Settings → Applications.

    How is this different from a full check?

    The audit looks at your live website from the outside. A full check also reads your code on GitHub, so it can find leaked secrets, risky packages and database rules that can’t be seen from the outside.
