Build, test, and execute GraphQL queries, mutations, and subscriptions
GraphQL Overview: GraphQL is a query language and runtime for APIs that allows clients to request exactly the data they need. Unlike REST APIs with multiple endpoints, GraphQL uses a single endpoint with flexible queries that specify the exact fields and relationships required.
Query Building Process: The query builder helps construct valid GraphQL operations by providing syntax highlighting, variable management, and real-time validation. It supports all GraphQL operation types including queries for reading data, mutations for modifications, and subscriptions for real-time updates.
Request Execution: When you execute a query, the builder sends a POST request to your GraphQL endpoint with the query, variables, and headers. The response includes the requested data in JSON format, along with any errors and execution metadata for debugging and optimization.
Advanced Features: The tool provides features like variable substitution, header management, response formatting, and execution timing. It helps developers test GraphQL APIs, debug queries, and understand the structure and performance characteristics of their GraphQL operations.
Our comprehensive GraphQL Query Builder is a powerful online tool designed for developers, API testers, and GraphQL enthusiasts who need to build, test, and execute GraphQL operations efficiently. This free tool supports all GraphQL operation types including queries, mutations, and subscriptions, providing a complete testing environment for GraphQL APIs. The builder features syntax highlighting, variable management, header configuration, and real-time response formatting to streamline your GraphQL development workflow.
The GraphQL Query Builder offers advanced features like sample query loading, JSON variable formatting, response timing analysis, and comprehensive error handling. It supports custom headers for authentication, CORS handling, and API key management, making it suitable for testing both public and private GraphQL endpoints. The tool provides detailed response information including execution time, status codes, and formatted JSON output for thorough API analysis and debugging.
Security and privacy are fundamental to our GraphQL Query Builder. All operations are performed client-side with no query data stored on our servers, ensuring your API credentials and sensitive information remain secure. The tool follows GraphQL best practices for query construction, variable handling, and error management. Whether you're developing mobile applications, web services, or microservices architectures, our GraphQL Query Builder provides the essential tools for effective GraphQL API development and testing.
