GraphQL Explorer & Query Validator LOCAL ONLY

Inspect GraphQL SDL or introspection JSON, list types and query fields, validate copied root selections, and generate a variables template in the browser.

All parsing and analysis stays in this browser. Nothing is uploaded or sent to an API.
Schema or introspection JSON
Operation to validate

This is a schema and query helper. It does not send the operation, variables, or schema to a GraphQL endpoint.

Types and root fields
  • Paste a schema to inspect types, root fields, and a local operation.

Validate GraphQL structure before using an API client

The explorer identifies common SDL and introspection structures, checks root fields, and creates a starting variables object. It is not a replacement for server-side GraphQL validation.
