PortableLinuxApps are apps that run on most 32-bit Linux-based operating systems, such as Ubuntu, Fedora, debian and derivatives. They are bundled into self-containing files: 1 app = 1 file. To use them, just download, chmod a+x, and run. AppImageKit lets you bundle apps nicely without dependencies other than the base OS image.
Please let us know via github if you'd like to contribute to code, documentation, or a better website.
