Supabase app built with GPT Engineer? Let’s review it.
Expert code review for Supabase apps built with GPT Engineer. We find GPT Engineer-specific bugs, fix Supabase security issues, and optimize performance. From $19.
GPT Engineer issues we find in Supabase projects
Problems specific to GPT Engineer's code generation patterns when building Supabase 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.
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.
