The Swagger Viewer Chrome extension allows users to view and render Swagger YAML/JSON files using Swagger-UI. This extension replaces Swagger code with a preview HTML in GitHub and can be used offline. It supports GitHub as the source site, and it supports OpenAPI versions 2.0 and 3.0, as well as file extensions such as YAML, YML, and JSON. Simply install the extension, open a Swagger page on GitHub, click on the extension icon, and start developing with ease. Check out the changelog for more information.
