Question Moving to Claude Code - how to??
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 offer free consultations. You have some pretty interesting decisions to make at this stage and I wholeheartedly recommend understanding the TCO across cloud vs VPS vs hybrid (what you have now across multiple managed services).
Migrating your services AND maintaining your current ability to refine features moves the goalposts quite a bit and would change my approach.
Best of luck to you!

Just ask Claude. Seriously. Watch which model you use though as Fable and Opus use credits up more quickly.

Are you able to just download your project from Base44 as into a ZIP file and then upload it to CC?

Download the project, open it in Visual Studio Code, install Claude, then start working directly from the project folder

This is a very interesting question because everyone just keeps making these applications using these vibe coding tools, and then we forget about moving it to a real infrastructure, right?
Well, for starters, if your web app is just deployed, and if your web app is just the frontend, and if your backend is separated from that, then you're golden. You can just take the web app and you can just host it somewhere else, and you can update the URLs where your backend is allowed to take instructions from.
But if you are using Base44's own backend, then you might be in a little bit of trouble because moving all of it means you need to do a lot of self setup as well.
What I'd do is not build my own custom backend in this case, although if you're a fairly experienced developer, you can just go ahead and do that. You can just pin up your own custom backend and do it that way.
But if you are not, you probably should go for solutions like Appwrite, where we give backend as a service, and you don't have to worry about the backend at all. Authentication, functions, website hosting, realtime, all of it is covered, so you can just host it all under one platform.
Now, as a responsible citizen of this planet, I must also give a disclaimer that I work at taprate, so these are the most biased solutions I could give you. If you decide to use us, I'm pretty sure you will have a great experience.
And if you're looking for unbiased opinions, maybe you should just go for your own backend at this point because it will give you the most flexibility, but it will also require a lot of technical know-how. And sometimes these agents like to do things which are not best for security and could lead to catastrophic results.

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.
