## 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 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`](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)

## 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`:



```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](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](./docs/deployment/intro.md) for more options, and detailed documentation for each.



## Redoc vs. Redocly API Reference



Redoc is Redocly's community-edition product. Looking for something more?

We also offer [hosted API reference documentation](https://redocly.com/docs/api-registry/guides/api-registry-quickstart/)

with additional features including:



* Try-it console

* Automated code samples

* Pagination

* Extra theme options



### Documentation and resources



- [Reference docs](https://redocly.com/docs/api-reference-docs/getting-started/) - we take care of the hosting

- [Redoc](https://redocly.com/docs/redoc/) - detailed documentation for this open source project (also in the `docs/` folder)

- [Command-line interface to bundle your docs into a web-ready HTML file](https://redocly.com/docs/cli/commands/build-docs/)

- API linting, bundling, and much more with open source [Redocly CLI](https://redocly.com/docs/cli)



## Showcase



A sample of the organizations using Redocly tools in the wild:



- [Rebilly](https://api-reference.rebilly.com/)

- [Docker Engine](https://docs.docker.com/engine/api/v1.25/)

- [Zuora](https://www.zuora.com/developer/api-reference/)

- [Discourse](http://docs.discourse.org)

- [Commbox](https://www.commbox.io/api/)

- [APIs.guru](https://apis.guru/api-doc/)

- [BoxKnight](https://www.docs.boxknight.com/)

- [Quaderno API](https://developers.quaderno.io/api)



_Pull requests to add your own API page to the list are welcome_



## Configuration



Redoc is highly configurable, see the [configuration documentation](docs/config.md) for details.



### OpenAPI specification extensions

Redoc uses the following [specification extensions](https://redocly.com/docs/api-reference-docs/spec-extensions/):



* [`x-logo`](docs/redoc-vendor-extensions.md#x-logo) - is used to specify API logo

* [`x-traitTag`](docs/redoc-vendor-extensions.md#x-traitTag) - useful for tags that refer to non-navigation properties like Pagination, Rate-Limits, etc

* [`x-codeSamples`](docs/redoc-vendor-extensions.md#x-codeSamples) - specify operation code samples

* [`x-badges`](docs/redoc-vendor-extensions.md#x-badges) - specify operation badges

* [`x-examples`](docs/redoc-vendor-extensions.md#x-examples) - specify JSON example for requests

* [`x-nullable`](docs/redoc-vendor-extensions.md#x-nullable) - mark schema param as a nullable

* [`x-displayName`](docs/redoc-vendor-extensions.md#x-displayname) - specify human-friendly names for the menu categories

* [`x-tagGroups`](docs/redoc-vendor-extensions.md#x-tagGroups) - group tags by categories in the side menu

* [`x-servers`](docs/redoc-vendor-extensions.md#x-servers) - ability to specify different servers for API (backported from OpenAPI 3.0)

* [`x-ignoredHeaderParameters`](docs/redoc-vendor-extensions.md#x-ignoredHeaderParameters) - ability to specify header parameter names to ignore

* [`x-additionalPropertiesName`](docs/redoc-vendor-extensions.md#x-additionalPropertiesName) - ability to supply a descriptive name for the additional property keys

* [`x-summary`](docs/redoc-vendor-extensions.md#x-summary) - for Response object, use as the response button text, with description rendered under the button

* [`x-extendedDiscriminator`](docs/redoc-vendor-extensions.md#x-extendedDiscriminator) - in Schemas, uses this to solve name-clash issues with the standard discriminator

* [`x-explicitMappingOnly`](docs/redoc-vendor-extensions.md#x-explicitMappingOnly) - in Schemas, display a more descriptive property name in objects with additionalProperties when viewing the property list with an object
