Reunite is a newly developed system designed to enhance the flexibility and capabilities of project management and configuration, addressing the limitations of previous systems like Workflows and the Developer portal beta. It integrates with identity providers for SSO, Git providers, and incorporates user feedback, offering features such as visual reviews and a Git-integrated online editor. The new system also distinguishes between "API registry" and "Remote content," allowing for more automated and configurable onboarding of APIs and other content types. Reunite supports roles and access management with free viewer seats, while contributors incur charges, and introduces three main unbundled products: Redoc for API documentation, Revel for external docs, and Reef for internal portals, all of which can be combined into a discounted package called Realm. The migration to Reunite involves connecting project repositories, setting up identity providers, and preparing content adjustments to ensure a seamless transition.
