Frequently Asked Questions

What is GraphQL SDL?

Schema Definition Language (SDL) is the standard syntax for writing GraphQL schemas, specifying types (type User { ... }), inputs, enums, interfaces, unions, and queries.

How do I extract introspection JSON from an active GraphQL server?

Send a POST request containing the standard getIntrospectionQuery query string, or run apollo-cli or graphql-inspector. You can drop that JSON result directly into this tool.

How does the mock query generator work?

When viewing a root operation (like Query or Mutation), clicking "Generate Mock Query" synthesizes an executable query selection set with arguments and fields.

Is my GraphQL schema kept private?

Yes. The entire parser and renderer execute client-side in your browser tab. No schemas or tokens are ever sent to an external server.
