Performance for your Cursor-built Firebase app
Expert performance for Firebase apps built with Cursor. We audit Cursor-generated Firebase code for performance issues. 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.
Firebase performance issues we check for
Performance-specific Firebase problems that need attention before production.
Inefficient Firestore queries
Reading entire collections when only a few documents are needed, or missing composite indexes causing query failures.
Runaway Cloud Functions
Cloud Functions that trigger other functions in infinite loops, or functions that don't handle errors and retry endlessly.
Uncontrolled Firestore costs
Read-heavy patterns without caching cause unexpectedly high Firestore bills as usage grows.
