Railway Security Best Practices

Secure your Railway deployments with these essential practices. From environment variables to database security.

Verify your app follows these best practices automatically.

Railway simplifies deployment, but application security remains your responsibility. Follow these practices to deploy securely on Railway.

Quick Wins

Verify no secrets in git repository
Switch to private database URLs
Configure separate environments
Test API routes without authentication
Enable deployment protection

Security Best Practices

#1Use Railway Variables for Secrets

critical

Never commit secrets to your repository. Use Railway's environment variable management.

Implementation

Add secrets in Railway Dashboard → Project → Variables

#2Use Private Networking for Databases

critical

Connect to Railway databases via private networking, not public endpoints.

Implementation

Use DATABASE_PRIVATE_URL instead of DATABASE_URL for internal connections

#3Enable Deploy Protection

high

Require approvals for production deployments to prevent accidental or unauthorized changes.

Implementation

Configure deploy protection in Project Settings

#4Secure API Routes

high

Validate authentication and authorization in every API endpoint.

Implementation

Check auth tokens and user permissions at the start of each route

#5Use Separate Environments

high

Use Railway environments to isolate production from staging and development.

Implementation

Create separate environments with their own variables and databases

#6Configure Health Checks

medium

Set up health checks to ensure only healthy instances receive traffic.

Implementation

Configure health check endpoint in Service Settings

Common Mistakes to Avoid

Using public database URL

Why it's dangerous:

Exposes database to internet, relying only on password

How to fix:

Use DATABASE_PRIVATE_URL for internal services

Same secrets in all environments

Why it's dangerous:

Production data accessible from development

How to fix:

Use separate environments with different credentials

No deploy protection

Why it's dangerous:

Anyone with access can push to production

How to fix:

Enable deployment approval requirements

Frequently Asked Questions

Are Railway environment variables secure?

Yes, Railway encrypts environment variables. They're only exposed to your deployments and not visible in logs.

Should I use Railway's managed databases?

Railway's managed databases handle security configuration automatically (encryption, backups, private networking). They're often more secure than self-managed for small teams.

How do I secure database connections?

Use DATABASE_PRIVATE_URL for private networking between Railway services. This keeps database traffic off the public internet.
