DeveloperBuild GraphQL queries, mutations, and subscriptions visually. Perfect for API development and testing.
Quick Templates
What is This Tool?
A GraphQL query builder creates GraphQL queries, mutations, and subscriptions with a visual editor. Build operations by selecting types and fields, add variables and arguments, and generate syntactically correct GraphQL documents ready for use in API clients and development tools.
GraphQL allows clients to request exactly the data they need in a single request. Queries follow a hierarchical structure matching your schema's type graph. This tool simplifies building complex queries with nested fields, arguments, fragments, and variables without memorizing schema structure.
Common Use Cases
API Exploration
Build and test GraphQL queries against APIs without writing raw query strings or using heavyweight IDE tools.
Frontend Development
Generate typed GraphQL operations for React Query, Apollo Client, URQL, and other GraphQL client libraries.
Documentation
Create example queries for API documentation, developer guides, and onboarding materials.
Testing
Build test queries for validating GraphQL resolver logic, authorization rules, and response formatting.
Frequently Asked Questions
What GraphQL operations are supported?
Queries (read), mutations (write), and subscriptions (real-time). Each supports variables, arguments, aliases, fragments, and directives.
Can I use variables?
Yes. Define variables with types ($id: ID!, $limit: Int) and reference them in arguments for reusable, parameterized queries.
Does it validate against a schema?
The builder generates syntactically correct GraphQL. Schema validation depends on the connected API or uploaded schema.
