Adding Firebase Auth to your Supermaven app? Let us review it.
Expert review for Firebase Auth integrations built with Supermaven. We fix Supermaven-generated Firebase Auth code for security, error handling & production readiness. From $19.
Common Supermaven issues affecting integrations
Fast completions accepted without review introduce subtle type errors
Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.
Security-sensitive code patterns completed without security review
In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.
Existing codebase anti-patterns replicated across new files at high velocity
Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.
Firebase Auth issues we find in Supermaven 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 Supermaven-built Firebase Auth integration?
Yes. We regularly audit Firebase Auth integrations in Supermaven-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Firebase Auth issues does Supermaven typically create?
Common issues in Supermaven-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 Supermaven 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.
