Firebase app built with GPT Engineer? Let’s review it.
Expert code review for Firebase apps built with GPT Engineer. We find GPT Engineer-specific bugs, fix Firebase security issues, and optimize performance. From $19.
GPT Engineer issues we find in Firebase projects
Problems specific to GPT Engineer's code generation patterns when building Firebase apps.
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Missing error boundaries
A single component error crashes the entire application. No error boundaries or fallback UIs to gracefully handle failures.
Firebase issues we check for
Common Firebase problems that affect production readiness.
Open security rules
Firestore and Realtime Database rules set to allow all reads and writes, making your entire database public.
Client-side admin SDK usage
Firebase Admin SDK credentials or service account keys exposed in client-side code.
Inefficient Firestore queries
Reading entire collections when only a few documents are needed, or missing composite indexes causing query failures.
No offline data handling
Apps crash or show stale data when connectivity drops because offline persistence isn't configured properly.
