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.

Railway publishes 1 API on the APIs.io network: Logs API. Tagged areas include Deployment, Platform-as-a-Service, Cloud, Infrastructure, and GraphQL.

The Railway catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Railway’s developer surface includes documentation, engineering blog, and 8 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/railway-app: open an issue to ask a question, or submit a pull request to add artifacts.
