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.
Cloudflare R2 issues we find in Create.xyz apps
S3 SDK configured with wrong endpoint format
AI-generated code uses incorrect R2 endpoint URLs (missing account ID, wrong region, or using AWS endpoints), causing all S3-compatible API calls to fail.
R2 credentials exposed in client-side code
Generated code includes R2 access key and secret key in the frontend bundle instead of keeping them server-side or using Cloudflare Workers with bindings.
Worker bindings not configured in wrangler.toml
AI tools write Worker code that references R2 bindings but don't add the corresponding [[r2_buckets]] configuration in wrangler.toml, causing runtime binding errors.
