Claude built your app.
VibeCheck catches what Claude missed.
You built it fast with an AI assistant. That is the right call. But AI coding tools optimize for working code, not launch-safe code. VibeCheck catches the security gaps, auth mistakes, and launch-killers that AI-assisted development often misses.

Why vibe-coded apps have unique launch risks
AI coding assistants are optimizing for one thing: code that works. They will scaffold your auth flow, generate your API routes, set up your database schema, and connect your payments. The code runs. The tests pass. The app looks great.
But "working code" and "launch-safe code" are different. The AI does not know that your Supabase tables have RLS off by default. It does not know your OpenAI key is now visible in the browser devtools. It does not test your Stripe webhook for signature verification. It has never seen your production environment — it cannot.
VibeCheck visits your app the way a real user does — and the way a real attacker does. It checks what's actually running, not what your code says should be running. Every check that fails is something the AI missed, something that could break your launch or expose your users.
The most common mistakes we catch in AI-built apps
These are real patterns — not hypotheticals. We see them in audits every day.
Supabase RLS disabled
Why the AI misses it
AI assistants create tables and write queries that work perfectly in tests — but they rarely write Row Level Security policies unprompted. The result: every authenticated user can read every row in your database.
What VibeCheck looks for
Checks for missing RLS configuration signals and attempts to access data endpoints without proper authentication headers.
OpenAI / Anthropic API key in client bundle
Why the AI misses it
AI generates code that works — and the shortest path to a working AI feature is often calling the API directly from the frontend. The AI doesn't know your key will be visible to every visitor in the browser devtools.
What VibeCheck looks for
Scans JavaScript bundles for API key patterns (sk-proj-..., sk-ant-..., gsk_...) that indicate an AI provider key has leaked into client-side code.
Admin routes client-side gated only
Why the AI misses it
AI adds auth checks at the UI layer — it hides the admin button, redirects unauthenticated users in the React component. But the API route or Server Action that actually performs the admin operation is often left unprotected at the server level.
What VibeCheck looks for
Visits /admin, /dashboard/admin, and similar routes directly with no session cookie and checks if they return 200 or 401/403.
No rate limiting on AI endpoints
Why the AI misses it
AI assistants build functional code — they create /api/chat that calls OpenAI and streams the response. They don't know your API quota, your monthly budget cap, or that one user running a loop can drain $200 of credits in an hour.
What VibeCheck looks for
Checks for X-RateLimit response headers on /api/chat, /api/generate, /api/completion, and similar endpoints.
Missing error states
Why the AI misses it
AI scaffolds the happy path beautifully. The form submits, the data loads, the UI updates. But error handling — the empty state, the failed network call, the 500 from the API — is often skipped or left as a TODO.
What VibeCheck looks for
Triggers form submissions with bad data, disconnects simulated network requests, and checks whether error states are shown or if the UI hangs silently.
Staging indexed by Google
Why the AI misses it
AI deploys your app to Vercel. The preview URL works. But it doesn't add a noindex tag to your staging deployment — so Google crawls your unfinished pages, your test data, and your debug routes.
What VibeCheck looks for
Checks for noindex meta tag or X-Robots-Tag: noindex response header on staging and preview deployments.
Works with your vibe coding stack
VibeCheck works with any publicly accessible URL — no SDK to install, no config to write. It detects your stack automatically and runs stack-specific checks.
Vercel
Preview URL detection and noindex checking
Supabase
RLS misconfiguration and direct database access checks
Clerk
Auth flow testing and session handling
Stripe
Webhook signature verification and payment flow checks
Railway
Deployment environment and production mode checks
Fly.io
HTTPS enforcement and header configuration
