Snap is an application packaging and deployment system for Linux-based operating systems. Snap includes powerful sandboxing and security features, such as file system isolation, automatic updates, and integrated dependency management.

Snap applications, known as *snaps*, can be downloaded and installed using a command-line program, similar to other package management systems like APT or YUM.
