MockType.dev

The tool accepts a JSON snippet and instantly generates equivalent type definitions, schemas, or data‑model code in a variety of programming languages. Supported outputs include TypeScript interfaces, Zod validation schemas, Go structs, Python Pydantic models, and Rust structs, allowing developers to move from raw JSON to strongly typed representations without manual translation.

It is aimed at developers who need to prototype, validate, or integrate JSON payloads across multiple back‑end or front‑end stacks. By handling the conversion in a single step, the utility reduces the friction of writing repetitive type definitions and helps keep codebases consistent with example data structures.

The service is positioned as an experimental, zero‑friction productivity aid, focusing on quick, copy‑and‑paste usage directly from a web interface. It supports more than twenty languages overall, though the primary listed targets are the five mentioned above.
