v0 gave you the interface. Now it needs an application.

What v0 does well

v0 produces clean, idiomatic React with Tailwind and shadcn/ui that a senior engineer would be content to maintain. It's a genuinely good foundation — unusually, the code it writes is not the problem. What it produces is a UI, and teams often discover late that everything behind the components is still to be built.

• Next.js App Router
• React Server Components
• Tailwind CSS with shadcn/ui
• Mocked data or local state
• Vercel hosting

• 01

  State that was never meant to persist

  Components hold their data in local state or a hard-coded array, so the app forgets everything on refresh. Introducing a real data layer touches every component, which is why this gets more expensive the longer it's deferred.

• 02

  Server Actions used as an unguarded API

  Server Actions are public endpoints. Generated ones frequently skip the auth check and input validation because the only caller during prototyping was the form beside them.

• 03

  No data model, just component props

  The shape of the data is whatever each component happened to need. Deriving a coherent schema from that — and reconciling the three components that model the same entity differently — is the real first task.

• 04

  Rendering strategy chosen by accident

  Pages end up dynamic because something reads headers or cookies, and nobody notices until the bill or the latency does. Deciding what is static, cached or dynamic is a per-route decision the generator never made.

• 01

  Secrets in the client bundle

  API keys inlined into frontend code because the prototype had no server to hide them behind. Anyone can read them with view-source, and rotating them is the first thing we do.

• 02

  Authorisation checked in the UI

  The admin button is hidden from non-admins, and the endpoint behind it is wide open. Hiding a control is not access control, and this is the single most common serious finding.

• 03

  No migration history

  The schema exists because someone clicked through a dashboard. There's no record of how it got that way and no safe path to change it, so the first production schema change is terrifying.

• 04

  Nothing to catch a regression

  No tests, so the next AI-assisted edit that breaks checkout is discovered by a customer. This is what makes generated codebases feel fragile — not the code quality, the absence of a safety net.

1. 1

   Audit — 3 to 5 days

   We map every component to the data it implies, identify where the model conflicts with itself, and report what has to exist before this is an application. Written, ranked, and yours regardless.

2. 2

   Design the data model

   One coherent Postgres schema derived from the UI you already validated, with versioned migrations and row-level security from the first commit rather than added later.

3. 3

   Secure the server boundary

   Auth checks and schema validation on every Server Action and route handler, treated as the public endpoints they are — with tests that call them directly, not through the UI.

4. 4

   Auth, payments, and the rest

   Clerk or Auth.js, Stripe with idempotent webhook handling, background jobs and email — the infrastructure a UI prototype never needed.

5. 5

   Tests, caching and production

   Playwright over the core journeys, an explicit per-route rendering and caching strategy, Sentry and analytics, and a documented handover.

FAQ

v0 to Production: your questions.

• Will you keep the UI v0 generated?

  Almost always — it's the part with the least wrong with it. We connect it to a real data layer, which changes how components receive data but rarely how they look.

• We used v0 inside an existing Next.js app. Is that different?

  Better, usually. The infrastructure exists and the work is integrating the generated screens into your conventions and data model. That's a smaller engagement, and the audit will say so.

• Do we have to stay on Vercel?

  No. Next.js runs well on Fly, Railway, AWS or a container anywhere. We'll tell you what it costs at your traffic on each, because that's usually the actual question.

• What does this cost?

  The audit is $750 (₹22,000). A typical v0-to-production build starts at $2,500 (₹75,000) for auth, database and payments, with the full figure fixed after the audit — not estimated before it.

• Bolt to ProductionBolt gets you to a running product in an afternoon. We add the things it never had to think about — real auth, migrations, payments that can't double-charge, and a test suite that survives your next prompt.Read
