Adding Firebase Auth to your Magic.dev app? Let us review it.
Expert review for Firebase Auth integrations built with Magic.dev. We fix Magic.dev-generated Firebase Auth code for security, error handling & production readiness. From $19.
Common Magic.dev issues affecting integrations
Complex implementations that are difficult to maintain
Magic.dev's ability to generate large, multi-file implementations means it can produce sophisticated code that works but is hard for human engineers to understand, debug, or extend.
Security decisions made at scale without explicit review
When Magic.dev generates an entire feature spanning many files, security decisions — API authentication, data access patterns, input validation — are embedded throughout without a clear review surface.
Over-engineered solutions for straightforward requirements
Magic.dev tends toward comprehensive, extensible implementations. Simple CRUD operations may receive complex abstraction layers, generic type systems, and plugin architectures that add maintenance burden.
Firebase Auth issues we find in Magic.dev 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.

What Firebase Auth issues does Magic.dev typically create?
Common issues in Magic.dev-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 Magic.dev 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.
