Vibe Coding Security Scanner
Apps built with AI (Lovable, Cursor, Bolt, v0, Replit) ship fast and leak secrets just as fast. Paste your URL and CheckVibe scans the live site for exposed API keys, SQL injection, XSS, and 100+ more issues in about 30 seconds, with a copy-paste fix for each one.
No source code or login to your app required. CheckVibe scans your deployed URL like an attacker would.
The vulnerabilities AI code generators leave behind
OpenAI, Anthropic, Stripe & more, leaked in JS bundles
Unsanitized inputs reaching your database
Untrusted content rendered as code
Missing CSP, HSTS, X-Frame-Options
World-readable tables, open rules
Weak transport, insecure session cookies
Three steps. One pasted URL.

Frequently asked questions
- What is a vibe coding security scanner?
- It's a tool that automatically inspects an app built with AI coding assistants (Lovable, Cursor, Bolt, v0, Replit, Windsurf) for security vulnerabilities. CheckVibe scans your live URL for exposed API keys, SQL injection, XSS, misconfigured headers, weak SSL/TLS, and backend (Supabase/Firebase) misconfigurations, then gives you a copy-paste fix for each one.
- Why do vibe-coded apps need a security scan?
- AI code generators optimize for "it works", not "it is secure". They routinely ship hardcoded secrets in the client bundle, leave database tables world-readable, skip auth checks, and forget security headers. None of that breaks the demo, so it goes to production unnoticed, until someone finds it. A scan surfaces these before an attacker does.
- How long does a scan take?
- About 30 seconds. Paste your URL, and CheckVibe runs 100+ checks in parallel against your live site, with no install, no config, and no source code access required.
- Is it free?
- Yes. Scanning is free and you see your issue count and a sample finding immediately. A free account unlocks the full breakdown; paid plans add copy-paste AI fix prompts, more scans, continuous monitoring, and live threat detection.
- Does it work with Lovable, Cursor, Bolt, v0 and Replit?
- Yes, CheckVibe scans the deployed website regardless of how it was built, so any vibe-coding stack works. It specifically understands Supabase, Firebase, and Clerk, and detects secrets from OpenAI, Anthropic, Stripe and others in your JavaScript bundles.
- How does CheckVibe compare to other vibe coding security scanners?
- CheckVibe is the only one that also audits SEO (68 checks) and AEO/AI visibility (46 checks) alongside security. Vibe App Scanner, VibeEval, and Scanbee are security-only as of June 2026. We publish fact-checked, sourced comparisons against each of them at checkvibe.dev/compare.
