Viewer GraphQL

This tool functions as a GraphQL viewer and tester that connects to a designated endpoint, submits queries with optional variables and headers, and returns a structured JSON result for analysis. It targets developers, API teams, and QA engineers who need fast, in-context validation of schema behavior and data shapes against a live GraphQL service.
Conceptually, it accepts endpoint_url, query, operationName, headers, and variables, constructs a GraphQL HTTP request, and returns the server response, including data, errors, and extensions. It also records latency and status information to aid performance assessment and debugging.
Unique value arises from precise, in-session visibility into response structure, built-in support for persisted queries, and straightforward exports for sharing results with teammates. The tool is lightweight, does not require a browser extension or external libraries, and is suitable for rapid iterations during API design and testing.
Common use cases include validating new schema fields, testing complex queries with variables, teaching teammates about the schema, onboarding clients, and debugging failures where headers or variable inputs alter the response. It helps engineers iterate faster by reducing guesswork and surfacing exact server behavior.
