Railway is an infrastructure platform where you can provision infrastructure, develop with that infrastructure locally, and then deploy to the cloud. This integration allows you to seamlessly connect your Postgres, Redis, MySQL, or Mongo databases hosted on Railway to your Vercel production and preview deployments.
This integration will provide your Vercel production and preview deploys with access to your Railway project variables. You can configure which Railway environment will be connected to each Vercel environment individual.
For example, if you have a Railway project with the Postgres plugin, the DATABASE_URL variable will be available to your Vercel deployments.
