GNOME Remote Desktop is the remote desktop server of the GNOME project, the desktop environment used on many Linux distributions. It offers two protocol backends, RDP (through FreeRDP) and VNC (through LibVNCServer), and can run as a server for sharing a running session, as a single-user headless server, or as a headless remote-login server. Standard RDP clients, such as mstsc on Windows, can connect. It is software you run on your own Linux systems, and a possible alternative to a Windows RDS host or a commercial remote-access product for Linux desktops.
The project is open source under the GPL-2.0-or-later and is developed within the GNOME project. The GNOME Foundation, the non-profit organisation behind the project, is based in the United States. There is no vendor-hosted service: no traffic or data passes through a cloud run by the maintainers, and connections and stored data stay on systems you manage yourself. For a European organisation this means control over hosting and network, but also its own responsibility for configuration, updates and security.
