Flatpak

Applications using Flatpak need permissions to access resources such as Bluetooth, sound (with PipeWire), network, and files. These permissions are configured by the maintainer of the Flatpak and can be added or removed by users on their system. Another key feature of Flatpak allows application developers to directly provide updates to users without going through Linux distributions, and without having to package and test the application separately for each distribution. Because Flatpak runs in a sandbox, which provides a separate, ABI-stable version of common system libraries, it uses more space on the system than common native packages. However, OSTree, a technology underlying Flatpak, deduplicates matching files. This means that the first few Flatpak installations will occupy more space, but as more packages are added, the system will use space more efficiently. ==Flathub==

Flathub, a centralized repository (or remote source in the Flatpak terminology) located at , is the de facto standard for obtaining applications packaged with Flatpak. Packages are contributed by both Flathub administrators and application developers, with a stated preference for submissions directly from the application developers. Although Flathub is the de facto source for applications packaged with Flatpak, it is possible to host a Flatpak repository that is independent of Flathub. ==Support==

Theoretically, Flatpak apps can be installed on any existing and future Linux distribution, including those installed with the Windows Subsystem for Linux compatibility layer, so long as Bubblewrap and OSTree are available. It can also be used on Linux kernel-based systems like ChromeOS. ==See also==
