How to Move from Lovable to Base44 (The Complete Migration Guide)

Lovable and Base44 are both AI-first app builders, but they serve different stages of a product's lifecycle. Lovable is exceptional for UI prototyping with Supabase as an external backend. Base44 is a complete platform — it includes its own database (entities), backend functions, automations, user authentication, integrations (Stripe, Resend, Google, Slack, and 50+ more), all in one hosted environment.

If you've outgrown Lovable's prototype-level features and want a production-grade platform without managing your own infrastructure, Base44 is the natural next step.

Key Differences: Lovable vs Base44

What the Migration Involves

You cannot do a direct code copy-paste migration because Base44's backend architecture is fundamentally different from Supabase. Instead, you'll:

• Recreate your data models as Base44 Entities

• Export and import your existing data
• Copy and adapt your React component UI
• Replace Supabase client calls with Base44 SDK calls
• Set up automations and integrations natively

Step 1: Export Your Lovable Project and Data

Code export:

• In Lovable, push to GitHub (Settings → GitHub → Push)

• Clone the repo locally to review the component structure

Data export from Supabase:

• Open your Supabase dashboard

• Go to Table Editor → select each table → click Export CSV
• Save all CSV files — you'll import them into Base44

Step 2: Set Up Your Base44 App

• Create an account at base44.com

• Click New App → describe your app to the AI agent
• Give the AI a comprehensive brief:

I'm migrating a [CRM / project management tool / marketplace] from Lovable.
It has these data models: [list your Supabase tables and key fields].
Users can [describe core features].
I need: authentication, [key pages], and [integrations needed].

Step 3: Recreate Data Models as Base44 Entities

In Base44, your database tables become Entities (JSON schema objects). Example — if you had a Supabase projects table:

{
"name": "Project",
"type": "object",
"properties": {
"name": { "type": "string" },
"status": {
"type": "string",
"enum": ["active", "paused", "completed"],
"default": "active"
},
"description": { "type": "string" },
"due_date": { "type": "string", "format": "date" }
},
"required": ["name"]
}

Key difference: Base44 entities automatically include id, created_date, updated_date, and created_by — you don't define these.

Step 4: Import Your Existing Data

Base44 supports CSV import natively:

• In your Base44 app, open the admin panel for an Entity

• Click Import → upload your exported CSV from Supabase
• Map the CSV columns to your Entity fields
• Import and verify record counts

Step 5: Migrate React Components

Your Lovable React components will work in Base44 with one key change — replacing Supabase client calls with Base44 SDK calls:

Lovable / Supabase pattern:

import { supabase } from '@/integrations/supabase/client';

const { data } = await supabase
.from('projects')
.select('*')
.eq('user_id', user.id);

Base44 equivalent:

import { base44 } from '@/api/base44Client';

const projects = await base44.entities.Project.filter(
{ created_by: user.email }
);

The JSX, Tailwind styling, and shadcn/ui components copy across almost directly. Only the data fetching layer changes.

Step 6: Replace Supabase Auth with Base44 Auth

Lovable pattern:

const { data: { user } } = await supabase.auth.getUser();

Base44 pattern:

const user = await base44.auth.me();

Base44's auth system is fully managed — no JWT token configuration, no row-level security setup, no OAuth provider registration needed.

Step 7: Set Up Integrations (The Base44 Advantage)

Instead of writing custom API code for every integration, Base44 provides 50+ OAuth connectors you can authorize in one click:

• Email: Resend built in via base44.integrations.Core.SendEmail

• Payments: Stripe via Base44 Payments
• Google: Calendar, Drive, Gmail, Sheets — all OAuth-connected
• Slack, HubSpot, Salesforce, Notion, Airtable — all one-click

Tell the Base44 AI agent: "Connect Stripe for payments and set up a webhook that updates the subscription status on the User entity when a payment succeeds." It handles the implementation.

Step 8: Set Up Automations

Lovable has no native automation system. Base44 supports:

• Scheduled automations: Run a backend function every day at 9am

• Entity automations: Trigger a function when a record is created/updated/deleted
• Webhook automations: React to events from connected services (new Stripe payment, new Gmail, etc.)

Example: "Send a welcome email to every new user when they register" — one automation, zero custom code.

Migration Timeline

Is Base44 Right for Your Migration?

Choose Base44 if your app needs a fully managed full-stack environment with automations, built-in integrations, and zero DevOps overhead. Stay with Lovable + Supabase if you need maximum control over your PostgreSQL schema or want to self-host your backend long-term.
