GraphQL Query Builder

GraphQL Query Builder is a powerful, browser-based tool for developers to construct, test, and debug GraphQL API calls with ease. Simply point to any GraphQL endpoint, write your query or mutation in the dedicated editor, optionally include variables in JSON format, and execute with a single click. The response is displayed in a formatted, easy-to-read output panel. Built-in quick examples help you get started instantly, covering queries, mutations, and variable usage. Whether you're building new features, troubleshooting existing APIs, or learning GraphQL, this tool streamlines your development workflow. No installation required—just open and start querying.

Install GraphQL Query Builder at its install page.
