Common Base44 issues affecting integrations
Platform lock-in makes it expensive to migrate to self-hosted infrastructure
Base44 applications run on Base44's infrastructure with proprietary abstractions. If you need to migrate to AWS, Vercel, or a custom backend, you must substantially rewrite the application since the generated code is tightly coupled to Base44's runtime.
Auto-generated backend API lacks input validation and allows malformed data into the database
Base44's generated REST API endpoints often accept and persist any data that matches the field type without business-rule validation — missing required fields, out-of-range values, or invalid relationships are stored without error.
Limited customization of business logic after the initial app generation
Once Base44 generates the application structure, adding custom business logic that deviates from the generated patterns — complex workflows, conditional processing, third-party integrations — requires working around the platform rather than with it.
Firebase Auth issues we find in Base44 apps
No server-side token verification
AI-generated code checks auth state only on the client using onAuthStateChanged but never verifies the Firebase ID token on the server, allowing forged requests.
Firebase config exposed without App Check
Generated code includes the full Firebase config in client-side code without enabling App Check, allowing anyone to use your Firebase project resources.
Firestore security rules left as test mode defaults
AI tools leave Firestore rules in test mode (allow read, write: if true) or generate rules that don't properly check auth.uid against document ownership.

Frequently asked questions
Can you review my Base44-built Firebase Auth integration?
Yes. We regularly audit Firebase Auth integrations in Base44-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Firebase Auth issues does Base44 typically create?
Common issues in Base44-generated Firebase Auth code include: no server-side token verification, firebase config exposed without app check, firestore security rules left as test mode defaults. We fix all of these in our code review.
How much does it cost to fix my Firebase Auth integration?
Start with our code audit ($19) to get a complete list of Firebase Auth issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Firebase Auth best practices does Base44 typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Firebase Auth. Our review checks all of these and provides specific fixes.
