Mock GraphQL Schema Snippet Generator
Starting a GraphQL schema from scratch means making naming decisions and remembering the exact syntax for non-null fields, list types, and enums before you have even thought about the domain. A concrete starting point that already applies the conventions correctly — bangs for non-null, brackets for lists, proper enum blocks — lets you focus on the actual type design. This tool generates realistic, valid GraphQL type definitions you can adapt to your own domain. Each click produces one type definition drawn randomly from five options: User, Post, Product, Order (which also includes an OrderStatus enum), and Comment. The snippets include field types, non-null markers, relationships between types, and the built-in scalars — ID, String, Int, Float, and Boolean. No inputs are needed; each generate call returns a different type. Copy the snippet into a schema file, a GraphQL playground, or a mock server. Rename the types, adjust the fields, and wire up the resolvers. Because each snippet uses valid SDL, it parses immediately without syntax errors, which avoids the frustrating edit-validate-fix loop when you are learning the format.

FAQ
is the generated schema valid GraphQL
Yes. Each snippet uses correct GraphQL Schema Definition Language — non-null markers, list types, enums, and references between types — so it parses correctly and demonstrates the standard conventions you would use in a real schema.
which types can be generated
The generator picks randomly from five type definitions: User, Post, Product, Order (with an OrderStatus enum), and Comment. Each includes multiple fields and, where appropriate, references to other types. There is no option to request a specific type.
what do the symbols mean
An exclamation mark means a field is non-null, square brackets denote a list type, and ID, String, Int, Float, and Boolean are the built-in scalar types. Referencing another type, like author: User, defines a relationship between them.
