OpenSync, originally a proprietary device middle layer, has been made open-source since 2018, to promote innovation, eliminate vendor lock-in, and speed up time-to-market. The framework efficiently deploys and manages consumer services on a massively scalable and diverse hardware ecosystem. OpenSync decouples the service layer from the hardware layer by abstracting hardware interfaces and networking functions into a real-time programmable interface with infinite degrees of flexibility. Services can be developed, deployed, and upgraded from the cloud, interfacing with the OpenSync enabled hardware though standardized management APIs.
