Flatpak is an open source containerized package format similar to Snap. While Snap relies on a central repository for software, Flatpak can be installed from different sources. The primary source is Flathub.
One of Flatpak’s main goals is to increase the security of desktop systems by isolating applications from one another. This is achieved using sandboxing and means that, by default, applications that are run with Flatpak have extremely limited access to the host environment.
While application developers have control over the sandbox permissions they wish to configure, good practice is encouraged and can be enforced. For example, the Flathub hosting service places requirements on which permissions can be used, and software on the host may warn users if certain permissions are used.
This article focuses on useful Flatpak tools. Only free and open source software is eligible for inclusion.
