Turn your v0 prototype into a production app: the full checklist

Turn your v0 prototype into a production app: the full checklist

Last updated 15 April 2026 · 11 min read · By Hyder Shah
Direct answer

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

Start here

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.

  2. 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.

  3. 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 to checkout.session.completed and customer.subscription.*. Make handlers idempotent.

  4. 05

    Step 5 — Propagate every env var to Vercel

    In Vercel → Project Settings → Environment Variables, add every key your .env.local contains for Preview and Production. Redeploy so the build captures them.

  5. 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.

  6. 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.

  7. 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.

Turn your v0 prototype into a questions

How long does it take to ship a v0 prototype to production?+
A realistic timeline for a single engineer is 5–10 working days if the UI is complete: 2 days to wire a backend and schema, 1 day for auth, 1 day for Stripe, 1 day for env and monitoring, 1 day for the domain, 2 days for testing and error handling. Our Deploy-to-Production Pass does it in 7 days at $1,999.
Can I skip the backend and just ship a static v0 site?+
If your app has no user data, no login, and no payments — yes, ship it to Vercel as-is. A marketing page or a public tool is fine. The moment you have users, a login form, or anything that persists data, you need a backend. v0 does not give you one.
Do I need to migrate off v0 to go to production?+
No. You can deploy the exported v0 code directly to Vercel. You just have to add every backend concern yourself. Most of our v0 clients keep the v0 output and add infrastructure around it rather than rewriting.
What is the single biggest cause of v0 apps failing in production?+
Missing server-side error handling. v0 ships API routes and server actions without try/catch, input validation, or rate limits. One malformed request returns a 500 and the whole page crashes. Adding a wrapped handler with Zod validation and error logging is the single highest-leverage fix you can make.
How much does it cost to finish a v0 prototype?+
Our Deploy-to-Production Pass is $1,999 fixed for a 7-day turnaround and covers backend wiring, auth, env, monitoring, custom domain, and error handling. Finishing a full MVP end-to-end with new features is $7,499. Emergency Triage for a single blocker is $299. All fixed price.
What should I do before the Deploy-to-Production Pass?+
Give us access to the v0 project, the Git repo, Vercel, your domain registrar, Supabase (or whatever backend you already picked), Stripe if relevant, and Google Cloud for OAuth. We work from a shared access checklist — most clients complete it in under 30 minutes.
