Deploy your Zod app to Heroku
Step-by-step deployment help for Zod apps on Heroku. We fix Zod-specific deployment issues, configure Heroku, and get your app live. From $19.
Zod issues we fix before deploying
Common Zod problems that affect Heroku deployments.
Incomplete schema validation
Zod schemas that validate the happy path but miss edge cases like empty strings, negative numbers, or overly long inputs that break downstream logic.
Schema-data mismatch
Zod schemas that don't match the actual API response or database shape, causing runtime parse errors that crash the application.
Missing transform and refinement
Schemas that accept raw input without transforming (trimming strings, normalizing emails) or refining (custom business rules), leading to dirty data in the database.
No error message customization
Default Zod error messages exposed directly to users, showing technical details like 'Expected string, received number' instead of user-friendly messages.
Heroku deployment issues we check for
Common Heroku problems that break Zod 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
How do I deploy a Zod app to Heroku?
We handle Zod deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Zod project, then we configure Heroku, fix issues, and get your app live in production.
What Zod issues affect Heroku deployments?
Zod projects commonly have incomplete schema validation and schema-data mismatch. On Heroku, these combine with free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files to cause deployment failures.
Can SpringCode deploy my Zod project to Heroku?
Yes. We specialize in deploying Zod applications to Heroku. We audit your codebase for Zod-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Zod deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Zod project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
