How This Tool Helps Before Publishing
A little context makes the numbers more useful. Use these notes to understand where this tool fits inside content, SEO and website reviews.
Validate before sharing
Parser errors help catch broken braces, invalid fragments and malformed operations before a query reaches an API client.
Prepare compact queries
Minified output is useful for pasted snippets, test fixtures and places where compact GraphQL is easier to store.
Private browser-based formatting
GraphQL input is parsed in your browser, so API queries and internal schema notes do not need to be uploaded to a server.
