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.

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 Redocly Museum 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

- Ability to integrate your API introduction into the side menu

Usage

Redoc Community Edition is available as an HTML tag, a React component, and via the Redocly CLI (also distributed as a Docker image).

$3

If you have Node installed, quickly generate documentation using npx:

``bash
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.

$3

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 for more details.

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