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

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
  • Ability to integrate your API introduction into the side menu
  • High-level grouping in side menu with the x-tagGroups specification extension
  • Simple integration with create-react-app
  • Code samples support (with vendor extension)

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 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:

    <redoc spec-url="http://petstore.swagger.io/v2/swagger.json"></redoc>
    <script src="https://cdn.redoc.ly/redoc/latest/bundles/redoc.standalone.js"> </script>

Open the HTML file in your browser, and your API documentation is shown on the page.

Add your own spec-url to the <redoc> 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 for more details.

More usage options

Check out the deployment documentation for more options, and detailed documentation for each.

OpenAPI specification extensions

Redoc uses the following specification extensions:

  • x-logo - is used to specify API logo
  • x-traitTag - useful for tags that refer to non-navigation properties like Pagination, Rate-Limits, etc
  • x-codeSamples - specify operation code samples
  • x-examples - specify JSON example for requests
  • x-nullable - mark schema param as a nullable
  • x-displayName - specify human-friendly names for the menu categories
  • x-tagGroups - group tags by categories in the side menu
  • x-servers - ability to specify different servers for API (backported from OpenAPI 3.0)
  • x-ignoredHeaderParameters - ability to specify header parameter names to ignore
  • x-additionalPropertiesName - ability to supply a descriptive name for the additional property keys
  • x-summary - for Response object, use as the response button text, with description rendered under the button
  • x-extendedDiscriminator - in Schemas, uses this to solve name-clash issues with the standard discriminator
  • x-explicitMappingOnly - in Schemas, display a more descriptive property name in objects with additionalProperties when viewing the property list with an object
