You vibe-coded a SaaS — now make it production-ready
AI built your app in a weekend. But Cursor, Bolt, and Lovable do not verify your Stripe webhook actually works or that your database is not exposed. Here is what to check.
You used Cursor, Bolt, Lovable, or Claude Code to ship a SaaS product in days instead of months. The features work locally. The UI looks polished. But AI coding tools optimize for "it compiles and renders" — they do not verify that your Stripe webhook actually delivers events, that your Supabase RLS actually blocks unauthorized access, or that your production environment variables are correctly configured.
What AI coding tools cannot verify
AI generates code that looks correct. But production readiness is not about code correctness — it is about system behavior. Does the webhook endpoint receive events from Stripe in production? Does the database allow queries only from authenticated users? Are your secret keys actually secret? Are your email deliverability records configured? These require live probing, not static analysis.
The 5 most common vibe-coded launch failures
1. Stripe webhook using test-mode signing secret in production. 2. Supabase service-role key exposed in NEXT_PUBLIC_ variable. 3. Auth redirect URIs still pointing at localhost or preview URLs. 4. No rate limiting on API routes. 5. No monitoring — the founder discovers outages from customer emails, not alerts.
Security is not optional after vibe-coding
AI tools do not enforce security best practices. They generate working code, but "working" does not mean "secure." RLS policies may be too permissive, API routes may lack input validation, and CORS might be wide open. These are not hypothetical risks — they are the exact failures PreFlight catches on real vibe-coded projects every day.
Bridge the gap with automated verification
PreFlight is designed for exactly this workflow: ship fast with AI, verify with automated probes. Connect your providers (Stripe, Supabase, Vercel), run a check, and see exactly what is production-ready and what needs fixing. The AI built it — PreFlight proves it works. Ship when the checks are green, not when you hope everything is fine.
