Every change reaches production with a backup, and your data never leaves your network.
Someone on your team built an app in Base44 in a couple of weeks. People use it and save hours. Then comes the question: where’s the data?
Base44 lets you export the UI, but the database, users and logic stay on their servers. So IT usually picks between two bad options:
The app stops being used.
The team goes back to spreadsheets and loses what it gainedA new project for something that already worked.
Months of work, and it can no longer be changed in Base445,000of 380,000 apps
If nobody decides, the app stays in use with company data outside your control. In May 2026, an analysis of 380,000 AI-built apps (Lovable, Replit, Base44…) found around 5,000 exposing corporate data.

Screens, fields and flows change as usual, with test data. No tickets, no waiting.
Will they need to learn to code?No. They keep working exactly the same way.
They’re detected and applied on your server after a backup.
What if a change breaks something?It rolls back to the previous version. And if you want, IT reviews each change before it goes live.
Your own database (SQL Server, PostgreSQL…) and sign-in with company accounts: when someone leaves, they lose access.
Who else sees the data?Nobody outside. Not Base44, not Keep44: it lives on your infrastructure.
Inside your network, the app can read and write to SAP (OData) or your databases without opening your firewall to the internet.
If you’re in IT
If you built the app
Not a fit if EU data residency is enough (Base44 offers it on its Enterprise plan), if you want to leave Base44 for good for Vercel or Supabase (there are services for that), or if the app is still a prototype nobody relies on.
Keep44 comes from real migrations: Base44 apps moved onto a company’s Windows infrastructure (IIS and SQL Server), one of them in daily use inside its network. That’s where the diagnosis starts: what stays behind in Base44 when you export, what has to be rebuilt, and what IT will ask.
Diagnosis
A yes, a no, or a “yes, if…”, and why.
What needs to move: entities, functions, integrations and Base44 dependencies.
How it would look in your environment: server, database, access and network.
The risks and what IT needs to prepare.
A fixed price for the migration and maintenance.
Your Base44 account and real data aren’t needed.
The final migration price is set in writing after the diagnosis and before any work starts.
Step 1
€450 + VAT
Whether it can be done, how, and what it costs, in 2 business days.
GuaranteeFully credited if you go ahead with the migration.
Step 2
from €4,500 + VAT
The app on your infrastructure, with the data migrated and sign-in with company accounts.
GuaranteeThe Base44 version stays live until the new one is validated.
Step 3
from €250 /month + VAT
Changes made in Base44 keep reaching production.
GuaranteeIf you stop, the app keeps running on your servers.
Someone asks for a new field. It’s added in Base44 that same morning and reaches production with the next sync, backed up. The data is still on your server, with no months-long project.
Booking costs nothing. The diagnosis is fully credited if you go ahead with the migration, and if the report doesn’t make the next step clear, you don’t pay.
No payment now. A reply within 2 business days.
It only includes the UI. Without the database, users and server functions, the app won’t start outside Base44. That’s what the migration rebuilds.
It’s migrated once into your database. From then on, real data lives only on your infrastructure.
Windows Server with IIS and SQL Server, or Linux with Docker and PostgreSQL, on your servers or in your own cloud (Azure, AWS, Google Cloud).
No. The Base44 version stays live until the new one is validated.
For example built-in AI, email sending or some integrations. The diagnosis flags it and proposes an alternative, or puts it out of scope in writing, before you pay anything for the migration.
To export the code, yes (Builder or higher). The diagnosis checks it.
The app keeps running: it’s on your servers and documented. You just stop getting the sync and support.
Yes, in English and Spanish, remotely.
You’ll get an email within 2 business days to set up the diagnosis. No payment now.
