FAQ
Does this tool send any API requests?
No. This is a purely client-side tool. It formats, validates, and visualizes your GraphQL queries locally in the browser. No data is sent to any server.
What does the schema visualizer do?
You can paste a GraphQL introspection query response (the JSON you get from running an introspection query against a server), and the tool will parse and display all types, fields, arguments, and their types in an interactive, browsable tree.
How does query validation work?
The validator performs basic syntax checking: it verifies balanced braces and parentheses, ensures the query starts with a valid operation type (query, mutation, subscription, or a fragment), checks that field names follow GraphQL conventions, and looks for common structural errors. It does not validate against a specific schema.
What code snippets can I generate?
You can generate cURL commands, JavaScript fetch API calls, and Python requests code. Enter your endpoint URL in the sidebar to get complete, ready-to-run snippets with your query, variables, and headers.
Where is my query history stored?
Query history is stored in your browser's sessionStorage, meaning it persists within the current tab session but is cleared when you close the tab. No data is sent or stored on any server.
