Built with Create.xyz? Deploy it to Heroku.
Step-by-step deployment help for Create.xyz-built apps on Heroku. We fix deployment issues, configure Heroku 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 Heroku 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.
Heroku deployment issues we check for
Common Heroku problems that break AI-generated apps in production.
Free dyno sleeping causes cold starts
Eco and Basic dynos sleep after 30 minutes of inactivity. AI-generated apps with webhook receivers or background jobs break when the dyno is asleep.
Ephemeral filesystem loses uploaded files
AI tools save user uploads and generated files to the local filesystem, but Heroku's ephemeral FS wipes all changes on every dyno restart or deploy.
Database connection pool exhaustion
Heroku Postgres plans have strict connection limits (20 on Hobby). AI-generated apps open a new connection per request, exhausting the pool under moderate traffic.
Procfile missing or incorrect
AI-generated projects lack a Procfile, causing Heroku to guess the start command. For non-standard setups, this guess is often wrong.

Frequently asked questions
Can you deploy a Create.xyz-built app to Heroku?
Yes. We regularly deploy Create.xyz-generated projects to Heroku. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Heroku.
What Heroku 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 Heroku, these combine with platform-specific issues like free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files.
How do I get my Create.xyz project live on Heroku?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Create.xyz-built projects targeting Heroku, the typical path is: fix Create.xyz-specific code issues, configure Heroku settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Create.xyz app to Heroku?
Yes. We handle end-to-end deployment: auditing your Create.xyz codebase, fixing deployment blockers, configuring Heroku correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
