A Node.js tool that spins up a full fake GraphQL API from a JSON data file with zero coding in under 30 seconds. Inspired by json-server, it auto-generates GraphQL types, queries, and relations from your data for learning, prototyping, and testing.

Use cases

• spin up a fake GraphQL API from a JSON file
• learn GraphQL without installing many packages
• mock a GraphQL backend for frontend development
• prototype an API before building the real backend
• run a local GraphQL server for testing queries
• generate a GraphQL schema automatically from data

When to choose

• you need a quick mock GraphQL server for development or demos
• you're learning GraphQL and want a working API immediately
• you want schema generation from existing JSON data with no code

When to avoid

• you need a production GraphQL API with custom resolvers, auth, or persistence
• you need mutations or complex business logic beyond simple CRUD queries
• your data doesn't fit the simple entity-with-id model
