IT can approve it, people sign in with their work accounts, and real data stays inside your network. If Base44 changes, the app keeps running.
Someone on your team built an app in Base44 in a couple of weeks. People use it every day. Then IT or the CISO asks: where does the data live, who can sign in, and can it run on the internal network?
Base44 has no on-premise option, and its export covers the UI only: the database, users and logic stay on its servers. So IT usually picks between two bad options:
The app stops being used.
The security review says no, and the team goes back to spreadsheetsA 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. Nothing goes live without passing through your environment.
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 your company directory (Microsoft Entra ID or Active Directory), confirmed in the diagnosis: 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), internal databases and APIs without opening your firewall to the internet.
If you’re in IT or security
If you built the app
Not a fit if Base44’s Enterprise plan (hosted by Base44, with single sign-on) already satisfies your IT team, 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.
Guide: how to run a Base44 app on-premise, on your own servers
When a client shows up with a Base44 app their IT won’t approve, Keep44 handles the migration and the Base44 Connection, and you keep the relationship. The fixed-price diagnosis gives you what you need to quote it.
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, corporate sign-in and network.
The risks and what IT needs to prepare for the security review.
A fixed price for the migration and the Base44 Connection.
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

GuaranteeFully credited if you go ahead with the migration.
Step 2
from $5,000
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 $300 /month
What lets you keep designing in Base44: every change reaches your server, reviewed.
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.
No payment now.
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. IT applies the changes made in Base44 using the documentation.
On every plan except Enterprise, Base44’s documentation (checked October 2026) says app data can be used to train AI models, with no opt-out setting. With the app and its data on your infrastructure, Base44 only sees test data.
That’s the plan: sign-in with Microsoft Entra ID or Active Directory, so access follows your existing accounts and offboarding. The diagnosis confirms how it fits your environment.
Yes. Everything is remote, in English, with calls scheduled in your time zone.
