Redocly
Beautiful API documentation from OpenAPI definitions, powered by open-source Redoc
About Redocly
Redocly is an API documentation and developer portal platform built on top of the popular open-source Redoc library. It enables API teams to generate production-ready, interactive reference documentation directly from OpenAPI, AsyncAPI, and GraphQL definitions. With a docs-as-code approach, Redocly integrates into existing Git workflows so documentation updates go through pull requests and deploy within minutes via CI/CD pipelines. The platform combines three core products: Redoc for API reference documentation with Try It console and mock servers, Revel for Markdown-based guides and React-powered custom pages, and Reef for API catalog governance with scorecards and lifecycle management. Redocly supports OpenAPI 3.2, 3.1, 3.0, Swagger 2.0, AsyncAPI, and Arazzo specifications, handling complex schema constructs like discriminators, oneOf, anyOf, and allOf seamlessly. Trusted by over 10,000 organizations including Brex, Checkr, and other enterprise companies, Redocly offers a powerful CLI for linting, bundling, and previewing API docs locally. The platform is designed for teams that treat documentation as code, providing version control, automated validation, and customizable theming to deliver a polished developer experience.
