About The Project

The Freedesktop SDK project is a free and open source project that provides Platform and SDK runtimes for Flatpak apps and runtimes based on Freedesktop modules. It was originally started as a Flatpak subproject to create a basic-neutral runtime. It is now a separate project, similar to what happened with the GNOME and KDE runtimes..

Along side Flatpak applications we are exploring how to use runtime in other ways, such as providing a minimal bootable system for anyone to use in their own project and bootable VM images which will use the freedesktop-sdk as a base.

This is a diagram of how the Freedeskop SDK runtimes interact with the rest of the Flatpak ecosystem

The Freedesktop SDK project is not an endorsement of a particular platform or selection of technologies by the Freedesktop organization. The SDK aims to support a common interoperable platform for projects such as GNOME, KDE and Flatpak by providing integration and validation of a shared set of dependencies.
