Redocly is an end-to-end API documentation and developer portal platform built around a docs-as-code philosophy. Its flagship open-source Redoc renderer auto-generates API reference docs from OpenAPI and related specifications. The commercial Realm suite bundles an external developer portal (Revel), an internal API service catalog with governance scoring (Reef), and the Redoc reference engine, unified under the Reunite collaborative editing and review layer. A CLI tool (Redocly CLI) enables OpenAPI linting, bundling, and automated CI/CD publishing from GitHub or GitLab. An API monitoring product (Respect) uses the OpenAPI Arazzo workflow standard to continuously test and verify API health with Slack and email alerting.
