"The Portable Linux Apps project brings the ideal of "1 app, 1 file" to Linux. Applications are able to run on all major distributions irrespective of their packaging systems - everything the application needs to run is packaged up inside of it. There are no folders to extract, dependencies to install or commands to enter: "Just download, make executable, and run!"" A follow-up article describes how it works, and how to transform debian packages into AppImages. The packages don't include libraries, so the system won't need to update the same library in each individual app.
