The MongoDB is renaming its Realm project to `MongoDB Atlas Device SDKs`, continuing to offer the device SDKs as a free and open-source project under the Apache 2.0 license. The company acquired Realm in 2019 and has been developing the project to provide developers with a synchronized data layer between devices and the cloud, supporting multiple programming languages, development frameworks, and cloud providers. The MongoDB will continue to develop the open-source code as Atlas Device SDKs, allowing developers to use it freely, with or without the MongoDB Atlas service, to build reactive mobile apps using their preferred technology.
