Snap
Also known as: snapd, Snap Store
Canonical's containerized package format for apps and services, installed from the Snap Store and default on Ubuntu.

Snaps bundle an app with its dependencies and run it under AppArmor confinement. They update automatically in the background and can hold command-line tools and server software as well as desktop apps.
