Example

Features

Major features:

  • Compares schemas
  • Finds breaking or dangerous changes
  • Validates documents against a schema
  • Finds similar / duplicated types
  • Schema coverage based on documents
  • Serves a GraphQL server with faked data and GraphQL Playground
  • GitHub Bot
  • GitHub Actions

GraphQL Inspector has a CLI and also a programatic API, so you can use it however you want to and even build tools on top of it.
