Supabase app built with Cursor? Let’s review it.
Expert code review for Supabase apps built with Cursor. We find Cursor-specific bugs, fix Supabase security issues, and optimize performance. From $19.
Cursor issues we find in Supabase projects
Problems specific to Cursor's code generation patterns when building Supabase 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.
Supabase issues we check for
Common Supabase problems that affect production readiness.
Missing Row-Level Security policies
Tables without RLS policies are accessible to anyone with the anon key. This is the #1 security issue in Lovable and Supabase-based apps.
Overly permissive RLS policies
RLS policies that use 'true' as the condition, effectively making the table public while giving a false sense of security.
Service role key in client code
The service_role key (which bypasses RLS) exposed in frontend code, giving attackers full database access.
Missing database indexes
Queries slow down as data grows because commonly queried columns lack indexes.

Frequently asked questions
Can you review Supabase code generated by Cursor?
Yes. We regularly audit Supabase projects built with Cursor and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Supabase issues does Cursor typically create?
Common issues in Cursor-generated Supabase code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. Combined with Supabase-specific concerns like missing row-level security policies and overly permissive rls policies.
How do I make my Cursor Supabase project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Cursor-built Supabase projects, the typical path is: fix security gaps, address Supabase-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Cursor-generated Supabase 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.
