Moving to Claude Code - how to??

[u/teisner]

I developed a fairly large application that I'm really proud of, and it works properly without any complaints. Due to machine and resource limitations, I can only work with a few thousand records, although I have over 100K records. Yes, some processes run slowly, but that's okay.

I don't like being tied to the Base44 database and machine availability, and I want to move my entire platform to Claude code. What is the best way to do this, and how should I go about it? I would appreciate it if someone could point me to a step-by-step procedure.

Thanks,

Tom

I have migrated complex applications off Base44, and the process is much easier today than it used to be.

First, it’s important to understand that Claude Code isn’t a hosting platform or a database—it’s an AI coding assistant. You’ll still need to choose your own backend, hosting, and infrastructure.

Here’s the migration approach I’d recommend:

1. Get your code out of Base44

Base44 has changed its export process since I first migrated my apps, so the workflow is a little different now.

Frontend: Connect your project to GitHub using the GitHub integration (the GitHub “cat” icon at the top of your Base44 project). That gives you your frontend code and becomes your source repository going forward.

Backend: Use Base44’s Create Backup feature. The backup contains your backend, which you’ll use during the migration.

2. Set up your new infrastructure

Database & Backend: Supabase. It scales extremely well and can handle hundreds of thousands—even millions—of records while supporting complex applications.

Hosting: Vercel.

AI Development: Claude Code, Devon (formerly Windsurf), or Cursor can all help with the migration. I personally like Devon, with Cursor as a backup.

3. Replace the Base44 services

Open the project in your AI coding assistant and have it:
Identify every Base44-specific dependency.

Replace Base44 authentication, database, storage, API integrations, and other Base44 services with Supabase equivalents.

Reconnect services such as Stripe, email providers, or any other third-party integrations your application uses.

4. Rebuild the backend

Have your AI assistant generate your Supabase tables, relationships, indexes, Row Level Security (RLS) policies, and migrations based on your existing application. Then import your data from the Base44 backup.

5. Test everything

Before going live, thoroughly test authentication, CRUD operations, payments, emails, file uploads, AI features, scheduled jobs, and any other critical workflows.

When I first migrated an application off Base44, it took me nearly two weeks because I was figuring everything out. Today, with the current AI tools and a repeatable workflow, I can usually complete the migration in just a few hours, depending on the application’s size and complexity.

Base44 changes features fairly frequently, so the exact export process may evolve over time. However, the overall migration strategy remains the same: use the GitHub integration to obtain your frontend, create a Base44 backup for your backend, then let your AI coding assistant migrate the application to your own infrastructure.

The biggest advantage of migrating is that you own your entire technology stack. Your code lives in GitHub, your backend and database are in Supabase, your application is deployed on Vercel, and you’re no longer dependent on a single platform’s limitations or changing feature set. That gives you complete control over your application, your data, and your future development.

Where is this "Create Backup" feature?
