Use the Railway Vercel integration to provide your production and preview deploys with access to your Railway environments.

Under Project Settings > Integrations in your project dashboard, you can connect to your Vercel account, specify a team, project, and production/preview environments. We will then provide your production and preview deploys on Vercel with all the environment variables needed to connect to your Railway environments.

This allows you to keep production and preview deploy databases separate.

Other Platforms

We are working on adding more integrations to various serverless platforms. However, if you want to use Railway for a platform we do not support, you can manually add the environment variables for each plugin (e.g. the DATABASE_URL for the Postgres plugin).
