Deploy your Remix app to Railway
Step-by-step deployment help for Remix apps on Railway. We fix Remix-specific deployment issues, configure Railway, and get your app live. From $19.
Remix issues we fix before deploying
Common Remix problems that affect Railway deployments.
Unprotected action functions
Remix action functions that modify data without verifying user authentication or authorization, allowing anyone to submit forms programmatically.
Missing error boundaries
No ErrorBoundary or CatchBoundary exports in routes, causing unhandled loader/action errors to crash the entire page.
Loader data over-fetching
Loaders returning entire database records to the client instead of selecting only the fields needed for rendering, leaking sensitive data.
Missing server-side form validation
Actions that trust client-side validation without re-validating on the server, allowing malformed or malicious data submissions.
Railway deployment issues we check for
Common Railway problems that break Remix 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.
