Turn your v0 prototype into a production app: the full checklist
Turn your v0 prototype into a production app: the full checklist
v0 ships a UI, not an app. To launch you still need to wire a backend, schema, real auth, payments, env vars, monitoring, a custom domain, and server-side error handling. Research shows 90% of vibe-coded projects never reach production. Follow the 8 steps below and yours will.
Quick fix for Turn your v0 prototype into a
Step 1 — Wire a backend
Add Supabase (fastest) or Neon + Drizzle (more portable). Install the SDK, initialise a server client, and move every data call out of the v0 stub into a server action or route handler.

Step 2 — Define the schema with migrations and RLS
Write migrations (Supabase CLI or drizzle-kit). Enable Row-Level Security on every table and add per-user policies. Index the columns you filter on. Test with two accounts in two incognito windows.
- 03
Step 3 — Make auth actually work in production
Add your production domain to the Google Cloud OAuth 2.0 Client redirect URIs. Set Supabase or NextAuth Site URL to the same domain. Make sure session cookies are set on the parent domain and not just the preview URL.
- 04
Step 4 — Add Stripe properly
Use Stripe Checkout, not custom forms. Create a webhook at
/api/stripe/webhook, verify the signature against the raw body, and subscribe tocheckout.session.completedandcustomer.subscription.*. Make handlers idempotent. - 05
Step 5 — Propagate every env var to Vercel
In Vercel → Project Settings → Environment Variables, add every key your
.env.localcontains for Preview and Production. Redeploy so the build captures them. - 06
Step 6 — Turn on monitoring and error tracking
Install Sentry (or similar), wire a global error boundary, and enable Vercel Log Drains. Add a third-party uptime check (Better Stack, Pingdom) hitting your root URL every minute.
- 07
Step 7 — Bind a custom domain
In Vercel → Domains, add your apex and
wwwsubdomain. Add the required A / CNAME records at your registrar. Set a canonical redirect (apex → www or vice-versa — pick one) and verify SSL issues. - 08
Step 8 — Add server-side error handling and validation
Every API route and server action needs Zod input validation, a try/catch, a structured error response, and a rate limit on writes. Wrap handlers in a helper and apply it everywhere.
Why AI-built apps hit Turn your v0 prototype into a
v0’s strength is generating React UI from a prompt. That is all it does. Every production concern lives outside v0 and has to be added by hand: data, auth, payments, monitoring, domain, and error handling.
The gap is invisible in v0’s preview because the preview stubs data and hides real users. It becomes visible the moment you publish — which is why so few v0 prototypes ever ship.

Diagnose Turn your v0 prototype into a by failure mode
Score your v0 project against this table. Any row marked “missing” is a launch blocker.
| Concern | What v0 gives you | What you need |
|---|---|---|
| Backend | None | Supabase, Neon, or equivalent |
| Database schema | None | Migrations, RLS, indexes |
| Auth | UI only; OAuth breaks on deploy | Working Google/email auth on prod domain |
| Payments | None | Stripe Checkout + webhook handler |
| Env vars | Local only | Set in Vercel for preview + prod |
| Monitoring | None | Sentry + Vercel logs + uptime check |
| Custom domain | None | DNS + Vercel project binding |
| Error handling | Minimal | try/catch + Zod validation on every route |
