API Factory - OpenAPI Viewer & Playground is a Chrome extension designed to streamline the process of working with OpenAPI specifications. This free tool automatically detects OpenAPI files in JSON or YAML format on any webpage, allowing users to view, test, and explore APIs directly within their browser. With no setup required, users can simply open the extension popup to start interacting with the API specs. This tool is ideal for API engineers and developers who need quick access to API documentation and testing without switching between multiple applications.

The extension offers several features that enhance productivity, including the ability to save time by eliminating the need to copy specifications into separate tools. Users can view clean, interactive documentation instead of raw code, experiment by testing endpoints directly in the browser, and easily collaborate by sharing specs or integrating with tools like Swagger UI and Redocly. With a focus on security, API Factory ensures that all operations run locally without collecting any user data.
