Change is essential to growth and progress in open source technology. MongoDB is announcing today that we’re renaming Realm to MongoDB Atlas Device SDKs. We will continue offering MongoDB Atlas Device SDKs as a free and open source project under Apache License 2.0.
MongoDB acquired Realm and its technology in 2019 and has continued development of the project to provide developers a synchronized data layer between devices and the cloud that makes it easier to build mobile applications, including support for multiple programming languages, development frameworks, and cloud providers.
MongoDB will continue open source development of Realm as Atlas Device SDKs, and developers are free to use the project — with or without MongoDB Atlas — to build reactive mobile applications using the technology of their choice.
Regular updates to the project will continue to be available on its Github repository. Please engage with us on the MongoDB Community Forum with questions or feedback.
