Swagger to Zod is a free Chrome extension designed to streamline the process of transforming Swagger/OpenAPI documentation into Zod schemas. Tailored for TypeScript developers, this tool integrates directly with Swagger UI, adding a convenient one-click button that allows users to copy API response definitions seamlessly as Zod schemas. It supports both OpenAPI versions 2.0 and 3.0+, ensuring broad compatibility with various API documentation formats.

The extension features intelligent parsing capabilities, automatically resolving local and remote $ref pointers and effectively handling complex nested structures. Users can enjoy a zero-configuration experience, as the tool functions immediately upon installation without the need for additional setup. Importantly, Swagger to Zod prioritizes user privacy by conducting all schema parsing locally within the browser, with no external API calls involved.
