Snap is a software package format created by Canonical which includes applications with required dependencies and libraries to run the application on a system. It is a universal approach to application packaging on Linux.
The applications packed in a snap will work across different distributions because they contain everything an application needs to run. As we are familiar with updating packages installed on Ubuntu or Fedora by using apt or dnf packages managers.
