In short, Flatpak is new technology for building and installing applications on the Linux Desktop. Its goal is to revolutionize the Linux desktop ecosystem and to overcome the application distribution problem on the Linux Desktop. Ideally, there will be a Linux app store in the future, where GNU/Linux distributions can obtain third-party applications.

Besides Flatpak, there is the Flathub website. Flathub is a build and distribution service for Flatpak applications. Its goal is to act as a central hub for making desktop applications available to users.

To download desktop applications on a Linux-based system, download the repository file and add it to your system with GNOME Software or the Flatpak command line.


On Debian-based systems flatpak can be installed as follows:

apt install flatpak

On Arch-based systems flatpak can be installed as follows:

pacman -S flatpak
