Overview
This GraphQL language implementation and runtime builds GraphQL servers in Ruby. Object types, fields, and query entry points are defined in Ruby code, and query strings are executed against the resulting schema. Rails applications can add the initial structure through generators.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Key features
Assemble types and schemas in Ruby code
Object types declare fields and return types, while a Query type provides the schema entry point. Passing a query string to Schema.execute resolves the selected fields and returns a result.

Best fit
Before adoption
Check the Ruby requirement and the paid-extension boundary
The v2.6.11 gemspec requires Ruby 2.7 or newer. The README lists persisted queries, API versioning, server-side caching, rate limiters, and several other capabilities under GraphQL::Pro, so confirm whether required features are part of the open-source runtime.

Supplemental curator note
Evaluate more than schema syntax: test authorization, data-loading behavior, and error responses with a small real query. If your design depends on GraphQL::Pro, confirm which capabilities sit outside the open-source runtime.
Try it in 3 steps
- 1
Add graphql to an isolated bundle
With Ruby 2.7 or newer and Bundler available, add v2.6.11 inside an empty evaluation directory.
mkdir graphql-ruby-demo && cd graphql-ruby-demo && bundle init && bundle add graphql --version 2.6.11 - 2
Create a minimal schema and query
Define a query entry point and one field, then execute a query at the end of the same file.
printf '%s\n' 'require "graphql"' 'class QueryType < GraphQL::Schema::Object' ' field :greeting, String, null: false' ' def greeting' ' "Hello from graphql-ruby"' ' end' 'end' 'class DemoSchema < GraphQL::Schema' ' query(QueryType)' 'end' 'puts DemoSchema.execute("{ greeting }").to_h' > demo.rb - 3
Inspect the query result
Confirm that the output contains
{"data"=>{"greeting"=>"Hello from graphql-ruby"}}.bundle exec ruby demo.rb
