Built with Cursor? Deploy it to Railway.
Step-by-step deployment help for Cursor-built apps on Railway. We fix deployment issues, configure Railway correctly, and get your app live in production. From $19.
Cursor issues we fix before deploying
Problems specific to Cursor's code generation that affect Railway deployments.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.
Railway deployment issues we check for
Common Railway problems that break AI-generated 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
Can you deploy a Cursor-built app to Railway?
Yes. We regularly deploy Cursor-generated projects to Railway. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Railway.
What Railway issues do Cursor projects typically have?
Cursor projects commonly have exposed api keys in client code and missing input validation on api routes. When deploying to Railway, these combine with platform-specific issues like nixpacks detects the wrong build system and volume data lost on redeploy.
How do I get my Cursor project live on Railway?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Cursor-built projects targeting Railway, the typical path is: fix Cursor-specific code issues, configure Railway settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Cursor app to Railway?
Yes. We handle end-to-end deployment: auditing your Cursor codebase, fixing deployment blockers, configuring Railway correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
