Guacamole is an HTML5 Web application that provides access to desktop environments using remote desktop protocols such as VNC or RDP. A centralized server acts as a tunnel and proxy, allowing access to multiple desktops through a Web browser. No plugins are needed. The client requires nothing more than a Web browser supporting HTML5 and AJAX.
RemoteBox is a graphical tool which lets you administer guests or virtual machines running under VirtualBox on a remote server or even your local machine if desired. You may, for example, have a root server on the Internet, a server at home, or a server at work running VirtualBox but want to have the convenience of managing the guests easily from your local machine. The virtual machines run in headless mode, which means you don't need an active graphical display on the server but you can still connect and view the displays of the guests. The goal of RemoteBox is to provide a GUI that should be familiar to VirtualBox users while allowing them to administer a remote installation of VirtualBox. It does this via the VirtualBox API and SOAP interface, which are exposed when running the VirtualBox Web service. You can also use RemoteBox simply as an alternative interface for managing VirtualBox on your local machine.
