Vibe Coding Security Scanner
Is Your AI-Built App Secure?
Find Out in Minutes — Free
Apps shipped with Cursor, Lovable, Bolt, v0, and Replit look done — but AI writes the happy path, not the security controls. Paste your URL and AI agents run real penetration tests against your app, the way an attacker would.
Why Vibe-Coded Apps Ship With Security Holes
AI coding tools are trained to produce code that runs. Security is invisible when everything works in the demo — so it gets skipped. These are the patterns we find over and over in AI-generated apps.
Exposed secrets & API keys
Keys hardcoded in client-side code or committed to the repo — visible to anyone who opens dev tools.
Missing authorization checks
Endpoints that authenticate the user but never check whether they're allowed to access the specific record.
IDOR / broken access control
Changing an ID in the URL returns another user's data because the query trusts the client.
SQL injection
String-built queries the model wrote for speed, with no parameterization or input validation.

What the Scanner Tests For
Real penetration testing across the OWASP Top 10 categories that matter most for AI-generated web apps — not just a header check.
SQL Injection
Tests database queries for injection that could expose or modify your data.
Cross-Site Scripting
Checks for XSS where attackers inject scripts into pages your users load.
Auth Bypass
Attempts to reach protected resources without proper authentication.
IDOR / Access Control
Checks whether changing an ID exposes another user's data.
SSRF
Tests whether your server can be tricked into making internal requests.
Path Traversal
Tests for access to files outside the intended scope.
Rate Limiting
Checks whether login and reset endpoints resist brute force.
Security Headers
Verifies CSP, HSTS, and X-Frame-Options are configured.

Frequently Asked Questions
Do apps built with AI coding tools have security vulnerabilities?
Frequently. AI coding tools optimize for working code, not secure code. Apps built with Cursor, Lovable, Bolt, v0, or Replit commonly ship with missing authorization checks, exposed API keys, SQL injection, and IDOR — because the model generates the happy path and rarely adds the controls a security-minded engineer would.
Which AI coding tools does the scanner work with?
All of them. The scanner tests your deployed app from the outside, so it's tool-agnostic — Cursor, Lovable, Bolt, v0, Replit, Windsurf, Claude, ChatGPT, or hand-written code. If it has a public URL, Nullscan can test it.
Is the vibe coding security scan free?
Yes. The free scan runs real penetration tests and returns the vulnerabilities found — titles, severity, and affected endpoints. Reproduction steps, proof-of-concept code, and fix guidance unlock for $39.
Is it safe to scan my AI-built app?
Yes. Nullscan performs non-destructive testing only — no denial-of-service, no credential brute forcing, no data exfiltration. It probes the way a real attacker would, but safely.
