Built with Create.xyz? Deploy it to Fly.io.
Step-by-step deployment help for Create.xyz-built apps on Fly.io. We fix deployment issues, configure Fly.io correctly, and get your app live in production. From $19.
Create.xyz issues we fix before deploying
Problems specific to Create.xyz's code generation that affect Fly.io deployments.
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.
Error handling is absent — unhandled exceptions produce blank screens or cryptic errors
Generated application code lacks try/catch blocks, error boundary components, and meaningful error messages. When an API call fails or unexpected input arrives, the application either crashes silently or shows a raw JavaScript error to the user.
Fly.io deployment issues we check for
Common Fly.io problems that break AI-generated apps in production.
Dockerfile missing or misconfigured
Fly.io requires a Dockerfile for deployment. AI tools that scaffold without one force flyctl to auto-generate a suboptimal Dockerfile that misses build steps.
Volume only available in a single region
Fly volumes are pinned to one region. Multi-region deployments try to access a volume that doesn't exist in other regions, causing crashes.
Machine restarts losing in-memory state
AI-generated apps store session data or caches in memory. Fly machines can restart or migrate, wiping all in-memory state without warning.
Internal DNS resolution failing between services
Services within a Fly organization communicate via <app>.internal hostnames, but AI-generated code hardcodes localhost or public URLs.

Frequently asked questions
Can you deploy a Create.xyz-built app to Fly.io?
Yes. We regularly deploy Create.xyz-generated projects to Fly.io. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Fly.io.
What Fly.io issues do Create.xyz projects typically have?
Create.xyz projects commonly have no authentication — all generated apps are fully public with no user accounts and hardcoded data and mock api responses replace real database or api integration. When deploying to Fly.io, these combine with platform-specific issues like dockerfile missing or misconfigured and volume only available in a single region.
How do I get my Create.xyz project live on Fly.io?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Create.xyz-built projects targeting Fly.io, the typical path is: fix Create.xyz-specific code issues, configure Fly.io settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Create.xyz app to Fly.io?
Yes. We handle end-to-end deployment: auditing your Create.xyz codebase, fixing deployment blockers, configuring Fly.io correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
