Common Create.xyz issues affecting integrations
No authentication — all generated apps are fully public with no user accounts
Create.xyz generates functional applications without any authentication system. Every page, API endpoint, and data resource is accessible to anyone with the URL, making it unsuitable for any application that handles user-specific or private data.
Hardcoded data and mock API responses replace real database or API integration
Generated applications use static JavaScript arrays or hardcoded JSON as data sources. There is no real database integration — data does not persist between sessions, is visible in source code, and resets on every page reload.
No input validation or sanitization on generated form and API handlers
Form submissions and API routes in Create.xyz-generated code process user input directly without validation, type checking, or sanitization, making them vulnerable to injection attacks and malformed data that breaks the application.
Supabase Auth issues we find in Create.xyz apps
Row Level Security policies not created or too permissive
AI-generated code creates tables without RLS enabled or adds overly permissive policies like 'true' for all operations, defeating the purpose of Supabase Auth.
Using anon key for server-side operations
Generated code uses the anon key in server-side API routes instead of the service role key, causing operations to fail or bypass RLS unintentionally.
Auth state not synced between client and server in Next.js
AI tools use createBrowserClient() everywhere instead of properly configuring createServerClient() with cookie-based sessions for Server Components and Route Handlers.
