quicktype is a code generation tool that produces strongly-typed models and serializers from JSON samples, JSON Schema, TypeScript, and GraphQL queries. It targets many languages including TypeScript, Python, Go, Rust, Java, C#, Swift, and Kotlin, and is available as a CLI, npm library, and web app.

Use cases

• generate typescript interfaces from
• convert schema to rust structs
• generate swift models from a api response
• create go structs from
• generate serializers for in kotlin
• turn graphql queries into typed models
• generate c# classes from

When to choose

• you need typed models and (de)serializers in one or many languages from JSON or JSON Schema
• you want to eliminate hand-written parsing boilerplate for JSON APIs
• you work across multiple languages and want consistent type definitions

When to avoid

• you need runtime schema validation rather than code generation
• your JSON is highly dynamic and not amenable to static typing
• you need a full ORM or database mapping tool
