Is my Base44 app secure?
A Base44 app is secure only if the database rules and the keys were locked down after it was generated, and by default those are the two things most likely to be wrong. Both are visible from your public URL, so you can confirm them in about a minute.
Full-stack fast means gaps hide
Base44 generates the frontend and the backend together and gets you live quickly. Every default it leaves on to stay fast is a place a security setting might be off. That is not a flaw in the tool, it is the reason you check the output before real users touch it.
A working app and a secure app are two different things.
What to confirm
- Is the database readable without a login? Turn on access rules scoped to each user.
- Did a secret key ship to the browser? Only publishable keys belong in client code.
- Are security headers set, and are source maps and .env private?
Paste your Base44 URL into Plaintext and it reports what is open, worst first.
Frequently asked
Are Base44 apps secure by default?
Base44 builds the app, but the access rules on your database and the handling of secret keys are yours to set. A Base44 app is secure once those are locked down, not automatically.
Can a Base44 app leak data?
Yes, if the database has no access rules or a secret key was exposed in the frontend. Both are checkable from the public URL and both are fixable once found.
Check your own app in about a minute. Paste your URL and Plaintext reads the shipped JavaScript, the public endpoints, and the database rules for the exact holes Base44 and other AI builders leave open. The first scan is free.
