Deploy your Kotlin app to Heroku
Step-by-step deployment help for Kotlin apps on Heroku. We fix Kotlin-specific deployment issues, configure Heroku, and get your app live. From $19.
Kotlin issues we fix before deploying
Common Kotlin problems that affect Heroku deployments.
Coroutine scope mismanagement
Launching coroutines with GlobalScope or unstructured scopes that outlive their intended lifecycle, causing memory leaks and zombie operations.
Null safety bypasses with !!
Using the non-null assertion operator (!!) to force past null checks instead of safe calls (?.) or elvis operator (?:), causing NullPointerExceptions.
Missing lifecycle awareness
Android components that don't respect Activity/Fragment lifecycle, continuing operations after destruction and causing crashes or memory leaks.
Insecure SharedPreferences
Storing authentication tokens and sensitive data in plain SharedPreferences instead of EncryptedSharedPreferences or Android Keystore.
Heroku deployment issues we check for
Common Heroku problems that break Kotlin 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 Kotlin app to Heroku?
We handle Kotlin deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Kotlin project, then we configure Heroku, fix issues, and get your app live in production.
What Kotlin issues affect Heroku deployments?
Kotlin projects commonly have coroutine scope mismanagement and null safety bypasses with !!. 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 Kotlin project to Heroku?
Yes. We specialize in deploying Kotlin applications to Heroku. We audit your codebase for Kotlin-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Kotlin deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Kotlin project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
