Getting a Base44 app out of Base44

What the Base44 export contains — and what it does not

• Comes out: the React front end, your entity definitions, and the source of custom backend functions.
• Stays behind: the runtime that executes those functions, the database with your data, authentication and user accounts, file storage, and any integrations configured in the Base44 dashboard.
• The result: exported code that runs only while it can reach Base44. It is a development convenience, not an exit.

What a real migration involves

• Translate the entity definitions into a Postgres schema (I use Supabase for most apps: auth, storage and functions come with it).
• Export the data through the Base44 API or dashboard, load it, and verify row counts and relationships on both sides.
• Recreate users: Base44 does not hand over password hashes, so users get a one-time "set your password" email on the new system, or sign in with Google as before.
• Port custom functions to Supabase edge functions or a small Node server; replace every Base44 SDK call in the front end with calls to the new backend.
• Re-wire integrations and webhooks (payments, email, calendars), then run both systems side by side until the new one is proven.

Is it worth it?

If the app is a personal tool, probably not. If people pay for it, your company runs on it, or a customer has asked where their data lives, yes — and sooner is cheaper than later, because every new feature built inside Base44 is one more thing to port. The first meeting is free and I will tell you plainly which side of that line you are on.
