Synology Application Package

Synology Package Files (SPKs) is the proprietary file format for installing and managing software on Synology's Network Attached Storage (NAS) devices. SPKs enable efficient distribution of packages compatible with Synology's NAS devices.

The packages available for Synology NAS typically come bundled with applications, services, and tools that are easy to install, configure, and manage. These include but are not limited to multimedia servers, cloud services, backup solutions, security software, add-on packages for existing applications, and custom or third-party software.

The SPK format offers a straightforward approach to deployment and maintenance, allowing users to access the Synology Package Center, a web-based application that facilitates package browsing, searching and downloading. Synology also supplies a Software Development Kit (SDK) to further facilitate software development and distribution.
