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.
Lemon Squeezy issues we find in Create.xyz apps
Webhook signature verification missing or incorrect
AI-generated handlers skip HMAC signature verification on incoming Lemon Squeezy webhooks, allowing anyone to forge subscription and order events.
Incorrect overlay checkout configuration
Generated code often misconfigures the Lemon.js overlay checkout, causing it to open in a new tab or fail to pass custom data back to your application.
License key validation not implemented server-side
AI tools frequently validate license keys on the client side only, making it trivial for users to bypass license checks entirely.
