There are many programs to access a computer from anywhere in the world with just a connection to the network, but today we come to tell you about a special one, it is the open source project Apache guacamole, which is a client (HTML5 web application) capable of offering you functionalities for remote access to servers and other remote computers from anywhere only with the help of a connection and a web browser.

And from LxA I encourage you to try it as an alternative to the other programs you use today, such as TeamViewer, TightVNC, UltraVNC, RealVNC, Vinagre, Xrdp, Viubo, and a long etc., since there are many different alternatives for many platforms.
