GraphQL Tester
Test GraphQL queries and mutations — send requests with variables and explore typed responses.
About GraphQL
GraphQL is a query language for APIs that allows clients to request exactly the data they need. Unlike REST where each endpoint returns a fixed data shape, GraphQL lets you specify precisely which fields you want in a single request. This tester supports queries, mutations, and subscriptions with variable injection.
FAQ
What is the difference between a query and a mutation?
Queries are read-only (like GET in REST). Mutations modify data (like POST/PUT/DELETE). Both use HTTP POST to the same endpoint.
