Writes variable definitions from the field arguments, such as $id: ID!
Expands nested object types up to 5 levels and stops at cycles
Handles union types with __typename and inline fragments
Skips fields you name so you can leave out heavy or private data
Creates a starter variables JSON with enum and input object samples

How do I generate a GraphQL query from a schema?

Paste the schema definition language, not an introspection result. If you only have a live endpoint, export the SDL with a tool such as get-graphql-schema first. Pick Query, Mutation or Subscription, choose a root field and set how deep to nest. The builder lists every scalar and enum field, follows object fields to your depth limit, and skips any field that needs a required argument because it cannot guess the value.

Privacy & Security

All processing happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
