Almost every AI app builder has an export button now. That is not the same as owning your app. The question that matters is simple: if the builder disappeared tomorrow, could you keep running what you built?
Here are six checks that answer it. You can do most of them in ten minutes on a free plan, before you put real work into anything.
Export something small and try to start it on your own computer. If the builder's documentation says running it elsewhere "takes engineering effort", believe it. When Mocha shut down in August 2026, its own announcement said exactly that about its export (source).
What you want is an export that starts with standard tools and nothing from the builder inside it. With SPOE that is one command, docker compose up, and our own CI checks that an export starts that way.

Some builders let you download code only on paid plans, and some tie it to keeping the plan. Read the pricing page for the word "export" or "download", and check what happens when you stop paying.
On SPOE, your first payment of any size, a plan or a one-off credit pack, unlocks export for good. It never locks again because you stopped paying. And the code is always visible and copyable in the editor, paid or not.
A login system and a database that only exist inside the builder are the hardest things to move. Your users' accounts and records are the part of the app you cannot rebuild from a description.
Look for a standard database you can copy, with its schema in plain files. A SPOE app uses Postgres, with every table defined in ordered SQL files in the project, so the database moves with the code.
If you hire someone, hand the app to a client, or sell the business, someone will ask what is in the code and where it came from. An unsigned ZIP proves nothing: anyone could have changed it.
Every SPOE export carries a signed manifest listing every file and the AI models that wrote and reviewed each change, plus a small script that checks the signature offline. Anyone can also drop the ZIP on spoe.ai/verify and check it in their browser, with nothing uploaded.
A model is a poor judge of its own code. Ask whether anything checks a change before it reaches your app. On SPOE, a second model from a different family reviews every change, and a change it flags waits for you instead of going in.
It happens. Firebase Studio stopped new sign-ups in June 2026 and closes on 22 March 2027, after which remaining workspaces are deleted (Google's notice). Ask yourself: if this tool sent that email today, would I lose anything?
If your answer to checks 1 to 3 was yes, the answer here is no.
Before you commit to any builder:
If any of that fails, you have learned the most important thing about the tool for free.
We built SPOE so every one of these checks passes. You can compare us with Lovable, Bolt, Base44 and v0 on the facts from their own pages, or start free and run the ten-minute test yourself.
