How to Move from v0 by Vercel to a Full App in Lovable or Base44

v0 by Vercel is arguably the best AI UI component generator available. Describe a UI, get production-quality React + Tailwind + shadcn/ui code instantly. But v0 has one fundamental limitation: it only generates UI. There's no database, no authentication, no backend logic, and no deployment pipeline built in.

When you're ready to turn your v0 UI into a real working application, you have two primary options: Lovable (Supabase-backed) or Base44 (fully managed full-stack platform). This guide shows you exactly how to migrate to both.

What v0 Gives You (And What's Missing)

v0 generates:

• React components (TSX) with Tailwind CSS

• shadcn/ui component usage
• Static mock data (no real backend)

What you still need to add:

• A real database and data persistence

• User authentication
• API and backend logic
• Page routing
• A deployment pipeline

Option A: Migrate v0 Components to Lovable

Step 1: Export Your v0 Code

In v0, click Copy Code on each component. Save each component to a local folder organized by component name. You can also use v0's GitHub export for larger projects.

Step 2: Create a New Lovable Project

• Go to lovable.dev and create a new project

• Describe your app briefly to let Lovable scaffold the structure
• Connect Supabase when prompted (free tier is sufficient to start)

Step 3: Import Your v0 Components

In Lovable's chat, paste your v0 component code with this prompt:

I have this React component generated by v0. Please integrate it into the app as the [page name] page.
Replace all mock/static data arrays with real Supabase queries.
Keep the exact same styling and layout — do not change the design.

Lovable will add the component, create the corresponding Supabase tables, replace static data with real queries, and wire up routing.

Step 4: Handle shadcn/ui Compatibility

Both v0 and Lovable use shadcn/ui, so component imports are typically compatible. If you see import errors:

"The Button component import is failing. Update the import path to match this project's shadcn setup."

Step 5: Add Authentication

v0 has no auth. Tell Lovable:

"Add Supabase authentication. Protect all pages except the landing page.
Add a login page with email/password and Google OAuth."

Step 6: Deploy

Lovable provides a built-in preview URL. For a custom domain, connect your Lovable project to Vercel or Netlify via the GitHub export.

Option B: Migrate v0 Components to Base44

Step 1: Create Your Base44 App

Go to base44.com, create a new app. Describe your app's purpose to the AI agent with full context about what pages you've already built in v0.

Step 2: Import v0 Components as Base44 Pages

Paste your v0 component into Base44's AI chat:

I have this React component from v0. Please create a new page called [PageName] using this component as the base.
Replace all mock data arrays with real Base44 entity queries using the pattern:
base44.entities.EntityName.list()
Keep all styling exactly as-is.

[paste v0 component code]

Step 3: Create Entities for Your Data

For each mock data type in your v0 component, ask Base44 to create an Entity:

"Create a Product entity with fields: name (string), price (number),
description (string), image_url (string), in_stock (boolean)"

Step 4: Wire Up Real Data Fetching

"Update the ProductGrid page to fetch real products from the Product entity
using useQuery and base44.entities.Product.list().
Show a loading skeleton while fetching. Handle empty state gracefully."

Step 5: Add Automations and Integrations

Unlike Lovable, Base44 lets you add business logic without writing backend code:

• "Send an email confirmation when a new order is placed" — entity automation

• "Connect Stripe so users can pay" — Base44 Payments built-in
• "Add a weekly digest email every Monday" — scheduled automation

v0 vs Lovable vs Base44: When to Use Each

The Most Efficient Workflow in 2026

Many high-velocity teams use v0 and Base44 together as a two-stage pipeline:

• Use v0 to rapidly prototype the exact UI — iterate until the design is right

• Copy the components into Base44 for the full-stack implementation
• Let Base44's AI wire up the backend, auth, and automations

You get v0's world-class UI generation speed with Base44's complete application platform — without writing a single line of backend code yourself.
