Is base44 safe?

Is a base44 app safe to ship?

base44 covers UI, backend entities, and workflow logic in a single tool, which is genuinely convenient for a founder who does not want to pick and wire together a stack. The tradeoff shows up in how those entities handle access by default.

What base44 actually does well

Covers the full app, frontend, backend entities, and workflow automation, without switching tools.

Lowers the setup cost for someone who does not want to choose and configure a separate database and API layer.

Ships working CRUD behavior for new entities immediately, which is what most early builds actually need first.

The gap

The gap: entities without an explicit access rule default to open

When base44 creates a new entity, it does not require you to set an access rule before the entity is usable, the same pattern that shows up across most AI app builders. An entity created without an explicit rule is readable by anyone who can reach the app's public API key, the same way an un-protected Supabase table is. This exact pattern turned up in our own scan of 66 live AI-built apps, covered in the data report linked below, where apps across several builders, including base44, shipped tables and entities with no access restriction at all.

60-second self-check

Check base44 for this yourself right now

About 60 seconds, and it mirrors the check for any AI builder with a public app-level API key.

  1. 01

    Open your live base44 app and open devtools, go to the Network tab, and reload the page.

  2. 02

    Find a request your app makes to fetch data, look at the request headers for an API key or token value.

  3. 03

    Copy that request as curl from devtools, then re-run it in a terminal from a session with no login, no cookies attached.

  4. 04

    If the entity data comes back anyway, that entity has no access rule restricting it, and anyone holding the same key can read it too.

Where the numbers come from

We scanned 66 live apps built with Lovable, Bolt, Cursor, base44, and Tempo. 41% of the Supabase-backed apps had at least one table anyone could read with the public anon key. The full methodology and findings are in the data report.

FAQ

Common questions about base44 security

No, it is the same default-open pattern seen across most AI app builders that create a backend for you. base44 is one of several tools where this exact gap showed up in our own scan of live apps, covered in the data report linked below.
Open the entity in the base44 dashboard and add an access rule that scopes reads and writes to the record's owner or an authenticated role, instead of leaving it open to any request carrying the app key.
Only ones that never had an access rule explicitly set. Entities you already scoped to a role or an owner are not affected.
In the apps we scanned, the entities most often exposed were user records, subscription and billing status, and private messages or support logs, the same categories that matter most if they leak.
Yes, the free Leak Check below scans your live URL for exposed keys and tests common access patterns automatically.
