Convex app built with Cursor? Let’s review it.
Expert code review for Convex apps built with Cursor. We find Cursor-specific bugs, fix Convex security issues, and optimize performance. From $19.
Cursor issues we find in Convex projects
Problems specific to Cursor's code generation patterns when building Convex 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.
Convex issues we check for
Common Convex problems that affect production readiness.
Missing access control on mutations
Convex mutations without identity checks, allowing any client to create, update, or delete data without authentication.
Overly broad queries
Queries that fetch entire tables without filters, sending massive amounts of data over real-time subscriptions and consuming read bandwidth.
No schema validation
Missing schema.ts definitions, allowing any shape of data to be inserted and causing type mismatches at runtime.
Inefficient reactive queries
Queries that re-execute on unrelated data changes because they scan too broadly, causing unnecessary re-renders in the frontend.

Frequently asked questions
Can you review Convex code generated by Cursor?
Yes. We regularly audit Convex projects built with Cursor and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Convex issues does Cursor typically create?
Common issues in Cursor-generated Convex code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. Combined with Convex-specific concerns like missing access control on mutations and overly broad queries.
How do I make my Cursor Convex project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Cursor-built Convex projects, the typical path is: fix security gaps, address Convex-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Cursor-generated Convex code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
