An open-source tool for generating beautiful, responsive API documentation from OpenAPI/Swagger definitions.
Redoc is an open-source tool that generates interactive API reference documentation from OpenAPI/Swagger specifications. It solves the problem of creating and maintaining developer-friendly API docs by automatically producing a responsive, three-panel interface from standard API definition files.
API developers, technical writers, and development teams who need to create and host documentation for RESTful APIs defined with OpenAPI or Swagger.
Developers choose Redoc for its beautiful out-of-the-box design, broad OpenAPI specification support, and flexible deployment options that work as a CLI tool, web component, or React component without requiring complex setup.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Features a responsive layout with synchronized navigation, documentation, and example panels for an optimal reading experience, as showcased in the demo image.
Supports OpenAPI 3.1, 3.0, and Swagger 2.0, ensuring compatibility with a wide range of API definition formats, as stated in the README.
Available as a CLI tool, HTML web component, and React component, allowing deployment from command-line to web apps with minimal setup.
Utilizes vendor extensions like x-tagGroups and x-codeSamples for enhanced navigation and code examples, though this requires modifications to the OpenAPI spec.
The free community edition lacks a built-in 'Try-it' console for live API calls, a feature only available in the paid Redocly API Reference, as admitted in the README.
Advanced functionalities like code samples and menu grouping depend on Redoc-specific vendor extensions, complicating spec maintenance and reducing portability to other tools.
Relies on JavaScript for interactivity, making it less suitable for static generation or environments with JS restrictions, and increasing initial load time compared to server-rendered alternatives.
