AppImage (formerly known as klik and PortableLinuxApps) is an open-source format for distributing portable software on Linux. It aims to allow the installation of binary software independently of specific Linux distributions. As a result, one AppImage can be installed and run across various GNU/Linux distributions without needing to use different files. It aims to be a format that is self-contained, rootless, and independent of the underlying Linux distribution.
Released first in 2004 under the name klik, it was continuously developed, then renamed in 2011 to PortableLinuxApps and later in 2013 to AppImage. Version 2 was released in 2016.
