Available Runtimes#

This page provides information about available Flatpak runtimes. It is primarily intended as information for application developers and distributors.

There are currently three main runtimes available: Freedesktop, GNOME and KDE. These are all hosted on Flathub. Each runtime comes with the corresponding SDK for building, and extensions for specific uses.

What is mentioned here is just a high level look at the contents. To have up to date information simply install the runtime and open a shell inside of it (flatpak run org.freedesktop.Sdk//23.08) from there you can look around or use tools like pkg-config --list-all. In the runtime shell you can also inspect /usr/manifest.json, which lists the sources used to build it.
