Snap is a software package management and deployment system developed by Canonical (Mother organisation of Ubuntu Linux). It's easy to deploy applications using the Snap tool. Snap package management system can work with most Linux distributions (e.g. Debian, Ubuntu, Fedora, Arch). Packages are called 'snaps' and the package management tool called 'snapd'. Linux users have to install the snapd tool in Linux to install applications in the snap repository.
