Railway
Railway is a cloud application deployment platform (PaaS) that builds, deploys, and scales services, databases, and cron jobs from a Git repository or Docker image. Its programmatic surface is a GraphQL-first Public API served at https://backboard.railway.com/graphql/v2 - the same API that powers the Railway dashboard. There is no REST API; all queries and mutations are issued as GraphQL POST requests, and real-time build, deployment, and environment log streams are delivered as GraphQL subscriptions over a WebSocket endpoint at wss://backboard.railway.com/graphql/v2.
