Is your Base44 app secure? Base44 security checklist
How secure is Base44?
Base44 (a Wix company) generates a full-stack app on a managed backend with built-in authentication, which handles a lot for you. The risk moves up a level: the common issues are data entities left readable or writable by everyone, roles that grant more access than intended, and third-party integration keys placed where the browser can read them. The platform works either way, so over-permissive settings ship unnoticed.
Base44 turns prompts into a working app with its own database, auth and hosting, so you're not wiring up Supabase yourself. That removes some classic mistakes and adds new ones: because access control is configured per data entity and per role, the thing to verify is who can see and change what.
The common risks in Base44 apps
Entities readable or writable by everyone
If a data entity's permissions are left public, anyone using the app (or its API) can list, edit or delete records that should be private to each user.
Over-permissive roles
Roles that grant broad access 'to get it working' can expose admin actions or other users' data to ordinary accounts.
Integration keys in the browser
Keys for third-party services (email, payments, AI) wired into client-side code are readable by any visitor via developer tools.
Unrestricted file or data exports
Endpoints that return records or files without checking the caller's permissions can leak data in bulk.
How to check your Base44 app
- Review each data entity's permissions and confirm users can only read and change their own records.
- Check every role and remove access that ordinary users don't need.
- Make sure third-party integration secrets live server-side, never in client code — open DevTools and search the bundle for sk-, SECRET and PRIVATE.
- Test the app logged out and as a basic user: try to reach data and actions you shouldn't be able to.
Scan your Base44 app before you launch
SafeLaunch checks your repo and live site in about 30 seconds and gives you a prompt to paste back into Base44 to fix each finding.
Base44 security FAQ
Is Base44 secure?+–
Base44 is a legitimate platform with built-in auth and managed infrastructure, and it fixed a disclosed vulnerability quickly in 2025. The remaining risk is in your app's own settings — entity permissions and roles left too open — which still ship past teams. An independent scan before launch is the reliable check.
Does Base44 handle security for me?+–
Base44 handles the infrastructure and authentication, but you configure who can access which data. Permissions left public are the most common issue, and the platform won't flag them for you.
How do I scan a Base44 app?+–
Run a SafeLaunch scan on your live app: it checks for exposed integration keys, data reachable without permission, and live-site setup, scores it, and gives you the exact fix for each finding.
