## About Redoc Redoc is an open source tool for generating documentation from OpenAPI (formerly Swagger) definitions. By default Redoc offers a three-panel, responsive layout: - The left panel contains a search bar and navigation menu. - The central panel contains the documentation. - The right panel contains request and response examples. ![Redoc demo](https://raw.githubusercontent.com/Redocly/redoc/main/demo/redoc-demo.png) ## Live demo If you want to see how Redoc renders your OpenAPI definition, you can try it out online at https://redocly.github.io/redoc/. A version of the Swagger Petstore API is displayed by default. To test it with your own OpenAPI definition, enter the URL for your definition and select **TRY IT**. ## Redoc features - Responsive three-panel design with menu/scrolling synchronization - Support for OpenAPI 3.1, OpenAPI 3.0, and Swagger 2.0 - [Multiple deployment options](https://redocly.com/docs/redoc/) - Interactive interface so your users can try the API immediately - Ability to integrate your API introduction into the side menu - High-level grouping in side menu with the [`x-tagGroups`](https://redocly.com/docs/api-reference-docs/specification-extensions/x-tag-groups/) specification extension - [Simple integration with `create-react-app`](https://redocly.com/docs/redoc/quickstart/react/) - Code samples support (with vendor extension)
![](docs/images/code-samples-demo.gif) ## Usage Redoc is provided as a CLI tool (also distributed as a Docker image), HTML tag, and React component. ### Generate documentation from the CLI If you have Node installed, quickly generate documentation using `npx`: ``` npx @redocly/cli build-docs openapi.yaml ``` The tool outputs by default to a file named `redoc-static.html` that you can open in your browser. > [Redocly CLI](https://github.com/Redocly/redocly-cli/) does more than docs; check it out and add linting, bundling, and more to your API workflow. ### Add an HTML element to the page Create an HTML page, or edit an existing one, and add the following within the body tags: ```html ``` Open the HTML file in your browser, and your API documentation is shown on the page. Add your own `spec-url` to the `` tag; this attribute can also be a local file. The JavaScript library can also be installed locally using `npm` and served from your own server, see the [HTML deployment documentation](https://redocly.com/docs/redoc/deployment/html/) for more details. ### More usage options Check out the [deployment documentation](./deploment/index/md) for more options, and detailed documentation for each. ## Redoc vs. Reference Redoc is Redocly's community-edition product.
