Symptoms
- You need features Base44 does not support
- Platform costs grow with your users
- Clients or investors ask where the data lives
- You want developers to work on the code freely
Why it happens
The React interface you export from Base44 can usually be reused. What changes is everything behind it: where the data lives, how users log in, where server functions run and where files are stored.
Plan it like a small migration, not a quick export. Done in the right order, your users barely notice the switch.
Try this first
-
List what the app uses from Base44
Write down every data collection, the login methods, server functions, integrations and file storage. This list is your migration plan.
-
Pick the new backend
Supabase is a common choice because it covers the database, logins, file storage and server functions in one place. Firebase and a custom API are other options.
-
Recreate the data and import it
Create matching tables on the new backend, then import the CSV files you exported from Base44. Check the row counts after the import.
-
Replace SDK calls one area at a time
Swap the Base44 calls for the new backend, one feature at a time, and test each one before moving on.
// Before: a Base44 entity call, for example // base44.entities.Task.list() // After: the same data from Supabase const { data: tasks, error } = await supabase .from('tasks') .select('*') -
Move your users carefully
Users usually keep their email address but may need to set a new password or log in with an email link the first time. Tell them before the switch, not after.
When to stop and call a person
This is a good job to hand to a developer. Migrations touch logins, data and payments at once, and mistakes are expensive. A specialist can plan the order, move the data and switch over with little downtime.
Questions people ask
Can I keep the same design?
Usually yes. The interface code comes with the export. Most of the work is behind the screens.
Will users have to sign up again?
Usually not. They may need to set a new password or use an email link once, depending on how logins are moved.
