What a Base44 Migration Involves: A Plain-English Plan

Moving a Base44 app to infrastructure you control comes down to four jobs: take stock of what the app depends on, decide where each piece will live, move it in a safe order, and test before you switch anything over. Exporting your code to GitHub covers only part of the first job.

This guide is for founders and builders who have a working Base44 app and want to know what a migration involves before they commit time or money to one. It is a planning guide, not a step-by-step build.

What a Base44 migration involves

A Base44 app is more than screens. Behind the pages sit several services that the platform runs for you. When you move, each one needs a new home or a replacement.

| Piece of your app | Question to answer before moving | |---|---| | Frontend (pages and components) | Can it stay as it is and point at a new backend? | | Database and entities | What data do you have, and where will it live? | | Authentication | How do existing users sign in on the new setup? | | Backend functions | Which ones exist, and what do they call? | | File storage | Where are uploads kept, and how are they linked? | | Integrations and secrets | Which third-party services does the app use, and which keys does it hold? | | Payments and email | Do webhooks or sending domains need to be re-pointed? |

If you want the full technical walkthrough of replacing each of these, read our free 26-phase migration guide. This article is the step before it: deciding what you are actually moving.

Step 1: Take inventory of what your app depends on

Open your app and list, in plain words, everything it does that a visitor does not see. Work through the table above and write one line per item. A spreadsheet is enough.

Two things catch people out:

• Backend functions nobody remembers. If an AI builder added a function for a feature you later dropped, it may still be there. Decide whether to move it or delete it.
• Secrets and keys. List every service the app talks to. You will need to create fresh keys on the new setup, so know what to replace.

Step 2: Decide where each piece will live

You do not have to pick one platform for everything. Many teams split the work: one service for the database, another for hosting, another for email. Common backend options include managed database platforms, a backend-as-a-service, or a server you run yourself. Each trades convenience for control and monthly cost.

Ask three questions for each piece:

1. How much do I want to manage myself?
2. What does it cost every month at my current size?
3. How hard is it to move again later?

Hosting, database, domain and AI-subscription costs are separate from any migration guide or service, so price your target setup before you start.

Step 3: Move in a safe order

A sensible order keeps the old app working while you build the new one:

1. Set up the destination (database, hosting, auth) and leave the live app untouched.
2. Move data first and check row counts match.
3. Recreate backend functions and point the frontend at them in a test copy.
4. Re-connect integrations with new keys.
5. Test the full path a real user takes: sign up, sign in, pay, receive email.
6. Switch your domain only when the test copy passes.

Step 4: Test before you switch

Write down five things a customer must be able to do and try each on the new setup. Include the boring ones: password reset, a failed payment, an email arriving in a real inbox. Keep the old app available for a few days so you can compare.

Do it yourself or have it done?

There are two routes, and the right one depends on your time and comfort with code.

• Self-guided. Kode Migration is a downloadable guide with ordered prompts you use with ChatGPT or Claude to scan your app, map the plan, and work through the migration. You stay in control of the code and the final testing. It is a document, not an automatic migrator.
• Done for you. If you would rather hand it over, see the Base44 migration service and send your app details.

FAQ

Does exporting to GitHub migrate my app? No. It gives you code, but the database, authentication, functions and storage still need new homes.

Can I use ChatGPT or Claude to help? Yes, if the assistant can see your app's files or a connected coding environment. A public app URL alone does not expose backend code.

Will my frontend need a rewrite? Often not. The goal is usually to keep the frontend and replace what it talks to, though that depends on your app.

Key takeaways

• List everything your app depends on before choosing a destination.
• Move data first, keep the old app running, and test real user paths.
• Choose self-guided or done-for-you based on your time, not on hype.
