X2Go enables you to access a graphical desktop of a computer over a low bandwidth (or high bandwidth) connection.

X2Go is a Remote Desktop solution, which some vendors vaguely call Remote Control. This is not to be confused with Microsoft Remote Desktop Connection, which is a competing Remote Desktop solution and protocol.

With X2Go, you mainly access Linux computers. The Linux computer you are accessing is the X2Go Server. (There are ways to connect to a Windows computer as well; some of them are only available with the Linux X2Go Client.)

You can connect from a computer running Linux, Windows or Mac OS X. This computer is the X2Go Client.

Multiple users/clients can access a single X2Go Server at the same time, with each user/client having an individual Desktop session by default - however, Desktop sharing (Remote Assistance) is possible, too (see below).

For the graphical part of remote desktop sessions, X2Go uses No Machine NX3 technology under the hood.
