About Redoc
Redoc is an open source tool for rendering API reference documentation from OpenAPI and Swagger descriptions.
The open source Redoc experience is primarily a documentation viewer. It helps people read and navigate an API description, but it is not a request-sending API client in the same way as Swagger UI or a REST client.
Redoc supports sending requests only in the paid plan. The open source version is view only.
Use our Online Redoc OpenAPI Viewer page when you want to load an OpenAPI file from a URL or from disk and inspect the rendered reference on this site.
What Redoc Shows
Redoc renders OpenAPI documentation with navigation, detailed reference content, schemas, and request and response examples.
The side-bar makes it easy to navigate through all the requests and see the full scope of endpoints and operations available.
It is often used when a team wants a polished API reference page that can be published as documentation and browsed by API consumers.
Like all tools offered by commercial vendors, Redoc has a non-configurable link back to the vendor site.
Redoc is supported natively in frameworks such as Docusaurus.
When To Consider Redoc
Redoc is a strong fit when your main goal is readable API reference documentation.
For exploratory requests and testing, Redoc can still be useful in combination with REST API tools because it makes the documented API structure easier to inspect.
