Deploy your Kotlin app to Railway
Step-by-step deployment help for Kotlin apps on Railway. We fix Kotlin-specific deployment issues, configure Railway, and get your app live. From $19.
Kotlin issues we fix before deploying
Common Kotlin problems that affect Railway 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.
Railway deployment issues we check for
Common Railway problems that break Kotlin apps in production.
Nixpacks detects the wrong build system
Monorepo projects or apps with multiple package managers confuse Nixpacks auto-detection, resulting in incorrect build commands and failed deployments.
Volume data lost on redeploy
AI-generated apps store uploaded files or SQLite databases on the filesystem without configuring Railway volumes, losing all data on each new deployment.
Private networking misconfigured between services
Internal service communication uses public URLs instead of Railway's private network (*.railway.internal), adding latency and exposing internal APIs publicly.
Health check endpoint missing
Railway restarts services that fail health checks. AI-generated servers often lack a /health endpoint, causing unnecessary restart loops.

Frequently asked questions
How do I deploy a Kotlin app to Railway?
We handle Kotlin deployments to Railway end to end. Start with our code audit ($19) to identify deployment blockers specific to your Kotlin project, then we configure Railway, fix issues, and get your app live in production.
What Kotlin issues affect Railway deployments?
Kotlin projects commonly have coroutine scope mismanagement and null safety bypasses with !!. On Railway, these combine with nixpacks detects the wrong build system and volume data lost on redeploy to cause deployment failures.
Can SpringCode deploy my Kotlin project to Railway?
Yes. We specialize in deploying Kotlin applications to Railway. We audit your codebase for Kotlin-specific issues, configure Railway correctly, and handle the full deployment so your app runs reliably in production.
What does Kotlin deployment to Railway cost?
Our code audit ($19) identifies all Railway deployment blockers in your Kotlin project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
