Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux.

See https://flatpak.org/ for more information.

Flatpak is available in the package repositories of most Linux distributions and can be installed from there. See https://flatpak.org/setup/ for quick setup instructions for many distributions.

Community discussion happens in #flatpak:matrix.org, on the mailing list, and on the Flathub Discourse.

Host Requirements

Flatpak aims to run on a wide variety of systems. It is therefore conservative with required dependency versions and kernel features.

Currently, the main branch requires at least kernel version 5.8 (for statx STATX_MNT_ID).
