But the AI won't catch everything.
Vibe coding is powerful. You can go from idea to deployed app in hours. But the AI assistant that helped you build it is optimizing for working code, not for launch-safe code. It does not know your Supabase RLS policies are off by default. It does not check if your OpenAI key is in your client bundle. It does not test your auth flow on mobile Safari.
Lighthouse is brilliant for performance — it will tell you your LCP is 4.2 seconds and your images are not optimized. But it will not tell you your AI endpoint has no rate limiting and a single user can drain your monthly API budget in four minutes. It will not catch that your environment variables are leaking through your Next.js config. It will not notice your Stripe webhook has no signature verification.
OWASP ZAP is a serious penetration testing tool used by security teams with weeks to spare. It is not what you reach for at 11pm before a Product Hunt launch. VibeCheck is. Paste a URL, get a prioritized fix list in three minutes, and ship with confidence.
How VibeCheck compares
VibeCheck is not a replacement for Lighthouse or security audits. It fills the gap between "it works" and "it is safe to launch."

Comparison reflects current feature set. "Partial" means the tool covers a subset of what is listed. Use multiple tools for comprehensive coverage.
What only VibeCheck does
AI Key Safety
Scans your client bundles and network requests for exposed OpenAI, Anthropic, Groq, and Google AI keys. Also checks if your AI endpoints have rate limiting — the most common "I got a surprise $3,000 bill" mistake for solo builders.
Stack-Aware Auditing
VibeCheck detects your stack — Next.js, Supabase, Stripe, Vercel, and more — and runs checks specific to how those tools work. Supabase RLS is checked differently than Prisma. Stripe webhook validation is checked at the right layer. No false positives from irrelevant checks.
Fix Prompt Generation
Every failing check comes with a structured fix prompt you can copy and paste directly into Claude, ChatGPT, or your AI coding assistant. Not "enable CSP headers" — the actual prompt that produces the diff, in your stack, with the right context.
Learns Across Audits
The check registry grows every week based on real failure modes from the community. When a new class of vibe-coding mistake surfaces — a new AI provider, a new auth library, a new deployment pattern — VibeCheck adds a check for it. You benefit without changing anything.
