API Builder vs GraphQL Explorer
One is built for general HTTP request workflows, the other for schema-driven GraphQL exploration and operation building.
API Builder is broader
API Builder is the right tool when you need to send and inspect ordinary HTTP requests across many APIs, with flexible headers, payloads, and request shapes.
GraphQL Explorer is more specialized
GraphQL Explorer becomes more useful when the workflow depends on schema introspection, query design, and GraphQL-specific structure rather than generic HTTP testing.
Choose based on protocol complexity
If the endpoint is just an HTTP request, start broad with API Builder. If understanding and composing GraphQL operations is the hard part, open the explorer first.
