Firebase app built with Cursor? Let’s review it.
Expert code review for Firebase apps built with Cursor. We find Cursor-specific bugs, fix Firebase security issues, and optimize performance. From $19.
Cursor issues we find in Firebase projects
Problems specific to Cursor's code generation patterns when building Firebase apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.
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.
