Yes, primarily because it is an open source solution that is available on GitHub. We have two GitHub repositories - AWS GameKit C++ SDK (https://github.com/aws/aws-gamekit) and Plugin Code: AWS GameKit for Unreal (https://github.com/aws/aws-gamekit-unreal). The plugin code is primarily the UI that is built on top of the C++ SDK code. A game developer can take the GameKit C++ SDK and customize it (add more APIs) to build their own backend features for Unreal or any other engine of their choice.
