Snap is a software management and deployment system that enables distribution-independent software deployment. The packages are called 'snaps' and one tool for using them is 'snapd'. Canonical, the developer of Snap, manages the Snap Store service through which snaps are deployed. snapd is a REST API daemon for managing snap packages. Users can interact with it using the snap client, which is part of the same package.
