Freedesktop.org is a project to work on interoperability and shared base technology for free-software desktop environments for the X Window System (X11) and Wayland on Linux and other Unix-like operating systems.

We are not a formal standards body. The standards published on these pages are active or tentative (if marked as such) specifications which desktop environments may implement to improve mutual compatibility, share code and pool resources.

Please report issues found on this website via xdg-specs at Freedesktop.org's GitLab instance.
