Read full descriptionHide full description
OpenAPI Viewer is the easiest way to explore, test, and understand OpenAPI 3.0 and 3.1 specifications on your Apple devices. Whether you're integrating a third-party API, reviewing your team's documentation, or testing endpoints on the go, OpenAPI Viewer gives you a clean, native interface built for developers. EXPLORE YOUR API Open any JSON or YAML OpenAPI file and instantly browse all endpoints organized by tag. Search across operations, schemas, parameters, and examples in seconds. View rich documentation for every endpoint — including descriptions, parameters, request bodies, and responses — with schema constraints, validation rules, and example values displayed clearly. TRY IT OUT Send real HTTP requests directly from the app. Fill in path, query, header, and cookie parameters, provide a request body, configure authentication, and hit Send. View the response body, status code, duration, and validation results — all without leaving the app. EXPORT AND SHARE Copy any request as a cURL command, JavaScript fetch, Swift URLSession, or Python httpx snippet — ready to paste into your terminal or codebase. BUILT FOR APPLE PLATFORMS A thoughtfully designed native UI makes even complex, sprawling APIs easy to read. Color-coded methods, clear badge indicators, and structured layouts — built for Apple platforms from the ground up. FREE TO USE OpenAPI Viewer is completely free with no subscriptions or paywalls. If you find it useful, you can support development through an optional tip jar — entirely your choice.
