The Security Scanner
Built for Vibe-Coded Apps
If you built your app with Lovable, Bolt.new, Cursor, Replit, or Google AI Studio, VibeCheck finds the security vulnerabilities that AI code generators commonly introduce.
What the Research Says
Escape.tech scanned 5,600 vibe-coded apps and found over 2,000 vulnerabilities and 400 exposed secrets. Tenzai tested 15 apps built with 5 AI coding tools and found 69 vulnerabilities including critical SSRF and injection flaws.
Why Vibe-Coded Apps Are at Risk
AI models optimize for working code, not secure code.
AI coding tools build full-stack apps in minutes. They skip authentication checks, expose database credentials, misconfigure Supabase RLS policies, and leave API routes wide open.
With Google AI Studio offering full-stack vibe coding with Firebase integration, and Lovable creating 200,000 new projects daily, attackers know where to look.

Two Ways to Scan
Most security scanners only do one or the other. VibeCheck does both.
Source Code Scanner
Analyzes your GitHub repository for hardcoded secrets, exposed credentials, misconfigurations, and vulnerable patterns in your code.
Live Site Scanner
Checks your deployed application for security headers, exposed files, CORS misconfigurations, and technology fingerprints.
Web App Security Best Practices
Implement these 6 practices to secure your vibe-coded applications
1. Enable Row Level Security (RLS)
Always enable Row Level Security on your Supabase tables. Without RLS, anyone with your anon key can read and modify your entire database.
ALTER TABLE users ENABLE ROW LEVEL SECURITY;2. Use Environment Variables for Secrets
Never hardcode API keys, database passwords, or JWT secrets in your source code. Use environment variables and secrets managers.
const apiKey = process.env.SUPABASE_KEY;3. Implement Security Headers
Add security headers like CSP, HSTS, and X-Frame-Options to protect against XSS, clickjacking, and protocol downgrade attacks.
Strict-Transport-Security: max-age=315360004. Sanitize User Input
Always validate and sanitize user input. Use parameterized queries to prevent SQL injection and output encoding to prevent XSS.
// Use parameterized queries
const { data } = await supabase
.from('users')
.select('*')
.eq('id', userId);5. Scan Dependencies for Vulnerabilities
Regularly audit your dependencies for known vulnerabilities. Update packages and use lock files to prevent supply chain attacks.
npm audit && npm update6. Implement Proper Authentication
Always authenticate users before granting access. Use secure session management, enforce strong passwords, and implement MFA for sensitive operations.
// Verify user session on protected routes
const { user } = await supabase.auth.getUser();
if (!user) return NextResponse.redirect('/login');Everything You Need
