MongoDB is rebranding its Realm technology as the MongoDB Atlas Device SDK, marking a significant shift in the company's approach to open-source development. The change aims to facilitate growth and progress in the technology landscape. The SDK will continue to be offered as a free and open-source project under the Apache 2.0 license. With this update, developers are now free to use the Realm technology with or without MongoDB Atlas to create reactive mobile applications using their preferred programming language, framework, or cloud provider. The project's periodic updates will remain available on its GitHub repository.
