Code Check Is Live: Find Out If Your Vibe-Coded App Is Safe to Ship

Code check on checkmyvibecode.com is Live: Find Out If Your Vibe-Coded App Is Safe to Ship

Last updated: October 2026

TL;DR: Code Check is a free tool on CheckMyVibeCode that scans your live URL or public GitHub repo and gives you a Vibe Score from 0 to 100. You see exactly what’s wrong, why it matters and how to fix it, plus a fix prompt you can paste straight into Claude Code or Cursor. Free accounts get 5 checks per month. Pro adds unlimited checks and weekly monitoring.

AI lets you build an app in a weekend. That’s the magic of vibe coding.

But AI writes code to make things work, not to make them safe. It forgets security headers. It leaves API keys where they don’t belong. It installs packages with known vulnerabilities. And because everything works, you never notice, until someone else does.

We built Code Check so you can find those problems before your users or attackers do.

What is Code Check?

Code Check is an automated health check for AI-built apps. Paste the link to your live app, your public GitHub repo, or both. About a minute later you get:

a Vibe Score from 0 to 100, a list of findings, sorted by how serious they are, a “How to fix” explanation for every issue, a fix prompt for Claude Code or Cursor that fixes everything step by step.

It works for websites, web apps, mobile apps, desktop apps and bots. For repos, we read your code, we never run it.

What does Code Check look for?

Code Check focuses on the mistakes that show up again and again in vibe-coded projects:

Area What we check Leaked API keys Secrets in your code or frontend that anyone could copy Security headers Content-Security-Policy, Referrer-Policy, HTTPS and more Database rules Common misconfigurations that expose your data Vulnerable packages Dependencies with known security issues SEO & speed Sitemap, compression and other basics that affect growth

Every finding shows its category, how many points it cost you and a plain-English explanation. No security degree needed.

Unlock deeper checks

Some checks are only fair to run on sites you own, for example whether your .env file or .git folder can be downloaded, or whether debug pages and source maps are public.

To unlock them, verify your domain once with a simple meta tag. Until then, those checks are skipped and cost you no points. You can also add a .checkmyvibecode file to your repo to show a “repo verified” label on your score.

A score you can trust

The Vibe Score is calculated with fixed, transparent rules, not AI guesswork. The same app gets the same score every time. AI only helps write the explanations, so they’re easy to understand.

To be clear about what it is: Code Check is an automated check, not a full security audit. It catches the most common and most dangerous mistakes, which for most vibe coders are exactly the ones that matter.

Score colors:

🟢 80–100: solid, ready to show off 🟡 50–79: works, but has gaps worth fixing 🔴 0–49: fix these before you share your app Fix everything with one prompt

This is where Code Check is different.

Most scanners give you a list of problems and leave you alone with them. Code Check gives you a ready-made fix prompt written for AI coding tools. It lists every issue, tells your AI to fix them one at a time, keep your app working the same, and never put secrets in code.

Copy it, paste it into Claude Code or Cursor, and let your AI clean up after itself. Then run a fresh check and watch your score go up.

You vibe-coded it. Now you can vibe-fix it.

Show off your score

A good Vibe Score is proof that your app isn’t just a weekend hack. So we made it easy to show:

Vibe Score badge: add it to your GitHub README or website with one line of code. It always shows your latest score. Public score page: a clean page with your score that anyone can visit. Your findings stay private, only you can see them. One-click sharing: share your score on X, Facebook, LinkedIn, Reddit or WhatsApp. Shared links get a preview image with your score. “Code Checked” band: projects with a score get a colored ring and a “Code Checked” label on their card on CheckMyVibeCode, so visitors see right away that you care about quality. Top Code Checked apps: the best-scoring projects get extra visibility on the platform. Pro: weekly monitoring that watches your back

You don’t ship once. You ship every day. Every new feature, every new package, every AI-generated change can break something that was fine last week.

With Code Check Monitoring, included in Pro, we re-check your projects automatically every week. You only hear from us when it matters:

a new critical issue appears (like a leaked key), or your score drops by 5 points or more.

You get an email and a notification on the site. Monitoring checks don’t count against any limit, and you can turn monitoring off per project anytime.

Is Code Check free? Yes. Every account gets 5 Code Checks per month for free. Pro gives you unlimited checks and weekly monitoring.

What can I check? Any project with a live URL or a public GitHub repo: web apps, websites, mobile apps, desktop apps and bots.

Do you run my code? No. We read your public repo, we never execute it.

Who can see my findings? Only you. Your public score page and badge show the score, never the findings.

Why were some checks skipped? Deep checks like .env and .git exposure only run on verified domains. Skipped checks don’t cost you points.

Does a high score mean my app is 100% secure? No automated tool can promise that. Code Check catches the most common and most dangerous mistakes in AI-built apps, and it’s the best first step before a full audit.

Can I check private repos? Right now Code Check supports public GitHub repos and live URLs.

Built with AI. Checked with confidence.

You put real work into your project. Make sure it’s solid before the world sees it, then show the world it is.
