Redoc
Open-source OpenAPI renderer with a three-panel docs layout.
About
Redoc is Redocly's open-source API documentation renderer. It turns OpenAPI 3.1, 3.0 and Swagger 2.0 definitions into responsive reference documentation with a signature three-panel layout: searchable navigation on the left, content in the center, and request-response examples on the right.
It ships as a CLI that generates self-contained static HTML, an HTML custom element for embedding in any page, and a React component. The project has over 25,000 GitHub stars and roughly a million weekly npm downloads, with organizations like Docker and Discourse using it for public API docs. Redocly also sells a hosted version with extras like a try-it console and mock servers.
