Migrate from Lovable Cloud Using Claude Code

Understanding the Vibes

When you click "Connect Supabase" in Lovable and don't select your own project, Lovable creates a managed Supabase instance for you. This is called Lovable Cloud.

It's convenient — you get a database without setup. But it comes with limitations:

• No SQL access — Can't run queries directly
• No custom auth — Only Google and Email
• No email templates — All emails from no-reply@auth.lovable.cloud
• No disconnect — Once enabled, permanent
• No monitoring — No real-time metrics

This guide helps you migrate to your own Supabase where you have full control.

What Makes This Different?

In the main guide, you do everything manually: clone repos, copy files, run SQL queries, import data.

With Claude Code, you tell it what you want and it does the work:

• Discovers your database schema automatically
• Exports all your data to JSON files
• Creates your new Supabase project
• Runs all your migrations
• Imports your data
• Updates your credentials

Same result, less clicking — or at least someone to troubleshoot with when things break.

What is Claude Code?

Claude Code is a command-line tool made by Anthropic that lets you chat with Claude directly in your terminal. Instead of copy-pasting between a chat window and your code, Claude Code can:

• Read your project files
• Run commands for you
• Make edits to your code
• Connect to APIs (like Supabase!)

Think of it as having Claude sitting next to you, but with access to your keyboard.

What You'll Need

Accounts:

• A GitHub account (free at github.com)
• A Supabase account (free at supabase.com)
• A Claude account with Pro plan ($20/month at claude.ai)

Your Lovable project:

• Already connected to GitHub

Time: About 30-45 minutes

Step 0: Install Claude Code + Supabase MCP

How to Install Claude Code

On Mac:

1. Open Terminal (Press Cmd + Space, type "Terminal", press Enter)
2. Paste this command:

curl -fsSL https://claude.ai/install.sh | bash

1. Close and reopen Terminal (important!)

On Windows:

1. Open PowerShell as Administrator
2. Paste this command:

irm https://claude.ai/install.ps1 | iex

1. Close and reopen PowerShell

Claude Code Pricing

Claude Code requires Claude Pro ($20/month). The pay-as-you-go option exists but is expensive and unpredictable — I don't recommend it.

Go to claude.ai/upgrade to subscribe. It's a paid service, no free tier for Claude Code.

First Run

claude

This opens your browser automatically. Log in with your Claude account and you're set.

Connect Claude Code to Supabase

Run this command:

claude mcp add --transport http supabase https://mcp.supabase.com/mcp

To verify, open Claude Code and type /mcp. You should see supabase in the list.

Step 1: Transfer Your Repository

Your code lives in a repository controlled by Lovable. We need to transfer it to YOUR GitHub account.

How to Transfer

1. Open your project in lovable.dev
2. Click the GitHub button in the top toolbar

1. Click Settings

1. Find Transfer ownership and click it
2. Select your personal GitHub account and confirm

Done! The repository now belongs to YOU.

Step 2: Clone with Claude Code

Open Terminal and navigate to where you want your project:

cd ~/projects
claude

Tell Claude:

Clone my GitHub repository [YOUR-REPO-URL] to this folder.
Then explore what I have - find the Supabase credentials, list tables, Edge Functions, and migrations.

Claude will:

1. Clone the repo for you
2. Read your .env file to find credentials
3. Parse src/integrations/supabase/types.ts for tables
4. List Edge Functions in supabase/functions/
5. Count migrations in supabase/migrations/

Save this summary — you'll need it later.

Step 3: Export Your Data

Tell Claude:

Export all my data from Lovable Cloud.

For each table, use the REST API and save to ./export/tables/{table_name}.json

Claude will create the folders and export each table automatically.

Step 4: Export Storage (If You Have Files)

Ask Claude:

Does this project use Supabase Storage? If yes, download all files to ./export/storage/

Step 5: Create Your New Supabase Project

Tell Claude:

Create a new Supabase project for this migration.
Show me my organizations first.

Claude will show your organizations and guide you through creating the project.

Step 6: Apply Migrations

Tell Claude:

Apply all migrations from supabase/migrations/ to my new project.
Skip any that fail and tell me which ones.

Step 7: Import Your Data

Tell Claude:

Import all data from ./export/tables/ into my new Supabase project.

Step 8: Upload Storage Files

If you exported storage:

Create the storage buckets and upload all files from ./export/storage/
Then update any URLs in the database that point to the old project.

Step 9: Deploy Edge Functions

If you have Edge Functions:

Deploy all Edge Functions from supabase/functions/ to my new project.

Step 10: Update Credentials

Tell Claude:

Update .env to use my new Supabase project.
Search for any hardcoded references to the old project too.

Step 11: Connect to Lovable

Now connect your migrated code to a fresh Lovable project.

Steps:

1. Create blank project in Lovable

Go to lovable.dev and create a new project. When asked what to build:

• Select "Other"
• Type: Import existing project from GitHub

2. Connect GitHub

Click the + button and select Connectors:

Go to Settings → GitHub → Connect. This creates a NEW repo in your GitHub account.

3. Tell Claude to push your code

Back in Claude Code:

Clone the new repo [NEW-REPO-URL] to /tmp/lovable-import
Copy all my migrated code there (everything except .git and node_modules)
Push to GitHub

Claude will:

1. Clone the empty Lovable repo
2. Copy your migrated code
3. Commit and push

4. Wait for Lovable to sync

Lovable will detect the changes and rebuild your app. This takes 1-2 minutes.

5. Connect Supabase in Lovable

Go to Connectors → Supabase:

Authorize the connection:

Select your new project:

Step 12: Run Security Advisor

After migration, check for security issues.

Tell Claude:

Run the security advisor on my new Supabase project.
Show me all warnings and explain what each one means.

Claude will:

1. Call the Supabase security linter
2. List all warnings (RLS issues, auth settings, etc.)
3. Explain each one in plain English
4. Suggest fixes

Common Issues:

RLS Policy Always True

• *What it means:* Anyone can INSERT/UPDATE/DELETE without restrictions
• *How to fix:* Add proper conditions to your policies

Leaked Password Protection Disabled

• *What it means:* Users can use compromised passwords like "123456"
• *How to fix:* Enable in Auth → Settings

Step 13: Test Everything

npm install
npm run dev

Verify:

• [ ] Data displays correctly
• [ ] Sign up / log in works
• [ ] File uploads work
• [ ] Audio/video plays

You Did It!

Your app now runs on YOUR Supabase with full control.

Troubleshooting

Storage Upload RLS Error

Ask Claude: Create an RLS policy that allows uploads to the bucket

URLs Point to Old Project

Ask Claude: Find and update all URLs with the old project ID

Lovable Shows Blank Page

Wait for sync. If it persists, create a fresh Lovable project and push again.
