AI app builders make it fast to get a working app. They make it much less obvious whether that app could ever run anywhere else. "You own your code" and "export to GitHub" are real features, but a repository on its own doesn't mean your business could keep running if you changed providers.
Whatever you built on, a portable app is more than its code. These six checks are the ones we run on every migration. Start with the information you have, and flag anything that needs a developer or platform support.
The six-point portability checklist
1. The code builds outside the platform
You have a repository in an account you control, and it builds and runs without the original vendor. How to check: clone it on a clean machine, install dependencies and build it. Note every environment variable or vendor key it asks for.
2. The database exports and restores
Schema and records can be captured, then restored into a different environment. An export you've never restored is a hope, not a backup. How to check: export everything, load it into a fresh database and compare row counts table by table.
3. Users and sign-in keep working
You know how accounts, sessions and roles would move, and what your users would have to do. Some platforms keep user accounts on their side, which can mean password resets after a move. How to check: find out whether user records and password hashes are part of any export.
4. Files and uploads come along
Images, documents and anything your users upload often live in the platform's own storage, separate from the database. How to check: list where stored files live today and how you'd download all of them.
5. Functions, integrations and secrets are accounted for
Account for every backend function, API, webhook, sign-in redirect and AI gateway your app depends on. Secrets are rarely included in exports, so you need your own copies of every key. How to check: search the code for calls to the platform's SDK and list every outside service it talks to.
6. Your next host fits the app
Your chosen provider needs to support the app’s runtime, database and day-to-day operations. For example, MongoDB and PostgreSQL need different database services. How to check: write down the language runtime, database type and any background jobs, then compare against the host. Our hosting guide compares the common options.
In a test environment with a copy of your data, take out every key that points back to the builder. Whatever stops working is your real migration list.
How each AI app builder compares
Every builder has a different exit. Broadly, they fall into two groups: platforms that give you a codebase to take away, and visual no-code platforms where leaving means a rebuild.
| Platform | What usually moves | What to watch |
|---|---|---|
| Base44 | Code via GitHub sync or ZIP (plan-dependent), table data as CSV | Exported code still calls Base44 for data, sign-in and functions; users and secrets stay behind |
| Lovable | Code, database contents and a documented backend path | Auth sessions, stored files, database policies, edge functions, OAuth redirects and AI gateways |
| Bolt.new | Standard web code, plus data from the connected database | Where data, logins and server logic actually live varies by project |
| Replit | Project code and PostgreSQL data with conventional tools | Independent backups, dev and production separation, a reproducible deployment |
| Emergent | Code via GitHub or copy, MongoDB data via a separate export | Code export excludes secrets and database contents |
| Bubble | Your data, with the app as a blueprint | No exportable codebase, so leaving means a rebuild |
| Glide | Your data, with screens and actions as the spec | No conventional codebase, so leaving means a rebuild |
Labels describe the typical starting point, not a guarantee. Platform features, plan entitlements and export paths change, so every app needs its own review. For a closer look at Base44, Lovable, Replit and Emergent, read the AI App Builder Reliability Report.
When to act
You don't need to leave a platform to benefit from this checklist. Running it now tells you how exposed you are, and fixing the cheap items (keeping your own copies of secrets, taking regular database exports and testing a restore) makes any future move faster. It's worth acting sooner if your app is starting to earn money, holds customer data you're responsible for, or has outgrown the platform's pricing or limits.
If you're on Base44, you can find out where you stand in a few minutes: connect your app with read-only access and we'll scan it and show your price. Small apps are a fixed $199.
