CodeCheck is a security scanner for vibe-coded and AI-built apps. You built something great with AI — but is it safe to put online? Paste your link and CodeCheck checks your app the way a hacker would — looking for leaked passwords, private data anyone can see, and other ways people sneak in. Then it tells you what's wrong and how to fix it, in plain English.
Free to start — no credit card. Full check from $4.99.
Works with the tools your AI app is probably built on
Watch a check happen.
Link in, fixes out — in about a minute. This is the real flow:
step 1 — that's literally it
If you can share a link, you can run a check.
You don't need to know security. That's our whole job.
AI writes code fast — but it often leaves the doors unlocked. Here's what CodeCheck watches for, so you don't have to.
Understands how your app is built
Paste a link — we figure out the tools behind it and run the right checks for each. No setup.
Keeps private data private
We check whether strangers can read your database — the #1 mistake in AI-built apps.
Spots leaked keys & passwords
Secrets left in the open get found — by us, before someone else.
Tells you exactly how to fix it
A short, prioritized to-do list with copy-paste snippets. No jargon.
Shows what could go wrong
For serious issues, we walk you through the exact path an attacker would take — then close it.
Safe to run, always
We only look — nothing on your site is ever touched or changed.

For every serious issue, CodeCheck shows you the story from a hacker's side: where they'd start, what they'd walk away with, and how fast it happens — all explained simply, using only what we safely found. So you get why it matters, not just a scary label.

Vibe coder questions, answered.
Everything people ask before running their first security check on an AI-built app.
Is my vibe-coded app safe to launch?
Maybe not. AI coding tools like Cursor, Lovable, Bolt, v0 and Replit write working code fast, but they routinely leave the doors unlocked — public databases, exposed API keys, and missing access rules. CodeCheck scans your live app the way a hacker would and tells you, in plain English, exactly what's exposed and how to fix it before you launch.
What security problems do AI coding tools leave behind?
The most common ones we find are unprotected databases (missing Supabase row-level security or open Firebase rules), API keys and secrets left visible in the browser, open MongoDB instances, SQL injection, missing rate limits on sign-in, and weak security headers. Over 70% of the apps CodeCheck scans are leaking something.
Which tools and stacks does CodeCheck work with?
CodeCheck works with apps built using Cursor, Lovable, Bolt.new, v0, Replit, Windsurf, Claude Code and any hand-written stack. It fingerprints and checks Supabase, Firebase, MongoDB, Postgres, Vercel, Netlify, Neon, PlanetScale, Convex, Clerk and Auth0 automatically — you just paste your link.
Do I need to know anything about security or code?
No. That's the whole point. If you can paste a link, you can run a check. CodeCheck explains every issue in plain English and hands you a short, prioritized to-do list with copy-paste SQL and config snippets — no jargon, no security degree required.
Will scanning break my app?
No. Standard scans are strictly read-only — CodeCheck looks the way an attacker would but never writes, changes, or deletes anything. Deeper active tests that could touch state are opt-in and only run after you verify you own the domain.
How long does a security scan take?
About 60 seconds to your first result. You paste your link, CodeCheck scans your live app, and you get a severity-scored report with fixes right away.
How much does CodeCheck cost?
It's free to start with no credit card — one surface scan a day. A one-time Deep Scan with the full AI fix report and exploit walkthroughs is $4.99, and Pro (unlimited deep scans plus automated weekly re-scans and alerts) is $20 per month.
Can I scan an app I didn't build?
Only if you own it or have written permission to test it. CodeCheck is for authorized testing only — deeper scans require you to verify ownership of the domain first.
Simple, honest pricing.
Catch problems before anyone else does — for way less than what a single leak would cost you.
