Deploy your Spring Boot app to Heroku
Step-by-step deployment help for Spring Boot apps on Heroku. We fix Spring Boot-specific deployment issues, configure Heroku, and get your app live. From $19.
Spring Boot issues we fix before deploying
Common Spring Boot problems that affect Heroku deployments.
Open actuator endpoints
Spring Boot Actuator endpoints like /actuator/env and /actuator/heapdump exposed without authentication, leaking environment variables, secrets, and heap memory.
Disabled Spring Security defaults
CSRF protection, CORS restrictions, and security headers disabled in SecurityFilterChain to 'make things work' during development and never re-enabled.
N+1 queries in JPA/Hibernate
Lazy-loaded entity relationships fetched inside loops, generating hundreds of individual SQL queries instead of proper JOIN FETCH or EntityGraph queries.
Missing @Transactional boundaries
Service methods that perform multiple database operations without transaction annotations, leaving data inconsistent if any step fails.
Heroku deployment issues we check for
Common Heroku problems that break Spring Boot 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 Spring Boot app to Heroku?
We handle Spring Boot deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Spring Boot project, then we configure Heroku, fix issues, and get your app live in production.
What Spring Boot issues affect Heroku deployments?
Spring Boot projects commonly have open actuator endpoints and disabled spring security defaults. 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 Spring Boot project to Heroku?
Yes. We specialize in deploying Spring Boot applications to Heroku. We audit your codebase for Spring Boot-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Spring Boot deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Spring Boot project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
