gqlgen vs GraphQL Ruby

gqlgen has no write-up on Specifiction yet; its figures are above.

GraphQL Ruby is a free, self-hosted Ruby gem that implements the GraphQL Server Specification for Ruby or Rails applications. It provides a self-documenting, strongly typed schema and serves queries, mutations, subscriptions, streaming responses, and multiplexed queries. Configurable depth and complexity validation can reject deeply nested or overly complex requests. Authorization tools handle schema visibility and checks on application objects during execution, while authentication is generally left to the application controller. GraphQL::Dataloader batches external data access and caches results per query; AsyncDataloader supports parallel I/O. Documentation covers Relay, Apollo Client, GraphQL.js Client, GraphiQL, urql, and custom JavaScript, plus monitoring integrations. The open-source gem is installed through RubyGems and uses the MIT license. The GraphQL Ruby gem costs nothing. GraphQL::Pro costs $1,100 a year, and GraphQL::Enterprise costs $2,400 a year under commercial licenses.
