Snappy is a software deployment and package management system originally designed and built by Canonical for the Ubuntu phone operating system. The packages, called 'snaps' and the tool for using them 'snapd', work across a range of Linux distributions and allow therefore distro-agnostic upstream software deployment. The system is designed to work for phone, cloud, internet of things and desktop computing - wikipedia 
# Snap format
The snap format is a single compressed filesystem that is mounted dynamically by the host operating system, together with declarative metadata that is interpreted by the snap system to set up an appropriately shaped secure sandbox or container for that application. File format extension is .snap .
