Guacamole est une application Web HTML5 qui permet d'accéder à un bureau à l'aide de protocoles de bureau à distance. Un serveur centralisé agit comme un tunnel et un proxy, permettant d'accéder à plusieurs bureaux via un navigateur Web. pas de plugins nécessaires. Le client ne nécessite rien de plus qu'un navigateur Web prenant en charge HTML5 et AJAX.
