quicktype

Turn JSON into typesafe code in any language.

quicktype infers types from JSON, JSON Schema, TypeScript, GraphQL, and Postman collections and generates models, serializers, and validators in over 25 target languages including TypeScript, Python, Swift, C#, Go, Rust, Kotlin, Java, C++, Zod, and Effect Schema. It detects enums, dates, UUIDs, nullables, unions, and maps, and can merge multiple samples for more accurate types. It is available as a browser app, a CLI (npm install -g quicktype), an embeddable quicktype-core library, and an MCP server at https://mcp.quicktype.io/mcp for AI coding agents. The project is open source with source hosted on GitHub.
