## What it is
graphql-ruby is a Ruby implementation of the GraphQL specification for building GraphQL server APIs in Ruby and Rails applications. It provides schema definition, queries, mutations, subscriptions, and production hardening features like complexity limits, tracing, and authorization integration.

## Use cases
- add a graphql api to a rails app
- build a strongly-typed graphql server in ruby
- implement graphql subscriptions and mutations
- serve graphql queries from a ruby backend
- integrate graphql with apollo client or relay
- add rate limiting and complexity limits to a graphql api
- set up persisted queries and api versioning for graphql

## When to choose
- you're building a GraphQL API in Ruby or Rails
- you need Relay-compatible schemas and subscriptions
- you want battle-tested GraphQL tooling used by GitHub and Shopify
- you need query analysis, tracing, or authorization integration in Ruby

## When to avoid
- you're building a GraphQL client in JavaScript rather than a Ruby server
- your app doesn't use Ruby
- you need a REST-only API with no GraphQL layer
- you need the Pro features (persisted queries, versioning) without a commercial license

## Facets
- artifact type: library
- maturity: stable
- function: graphql, api-framework, web-framework, middleware, authorization, caching, rate-limiting, tracing, websocket
- domain: web-development, backend, apis
- platform: ruby, cross-platform
- tags: graphql-server, rails, relay, schema-definition, subscriptions, dataloader, api-versioning, persisted-queries, ruby, web-server
