This website is dedicated to you, a small tribute that collects and lists your projects, and directs you to sources of alternative knowledge, too vast to be contained in these few pages. I invite you to explore them all and to use them as a springboard towards innovation, because culture is a right for everyone, and not only for those who submit their data to online services and to the big giants of the online market.
Special thanks also go to KaiosTech, for giving Firefox OS new life on these beautiful devices that we can all have.
This website was initially designed to entice ordinary people, like me, but with a great hidden talent, to implement new functions and bring into play their possibilities to make KaiOS better, through research, tests and the necessary tools made available initially from Mozilla and then from all communities, as external support for the official development of this software.

The initial gaps are gradually being lost between the lines of time.

I will never forget the early days when we tested to get the unofficial porting of important applications such as WhatsApp, when this seemed like a utopia, so much so that this software seemed like a joke to capture the attention of users, until december 2018. For us, who always believed in the potential of Firefox OS, it was a tough battle to face, difficult to overcome, and in some respects this is a battle that is not over for many of us yet!
Today KaiOS is an operating system within everyone's reach, from the user common to developers or aspiring developers, and my attention is dedicated to the latter.This site is used to guide users in the choice of devices, and to guide people towards the best choice.
Thanks also to HMD, which since the launch of its Nokia 8110 4G has tacitly consented to this research, paying attention to our request.
Because the sideload of third-party applications is not wrong, it belongs to the nature of Firefox OS, which is the heart that moves KaiOS.
I started this project and compiled this website on a domain that could be as accessible as possible and within my reach, with the hope that it will continue to grow and spread the basic knowledge of the tools, the awareness of your actions, the hope and the freedom of choice in the software field, and in particular on mobile devices.
I hope you know how to appreciate and support all this work that I have done for you with all my passion.
Thanks for your attention, and enjoy your stay on this site.

“The Matrix is a system, Neo. That system is our enemy. But when you're inside, you look around, what do you see? Businessmen, teachers, lawyers, carpenters. The very minds of the people we are trying to save. But until we do, these people are still a part of that system and that makes them our enemy. You have to understand, most of these people are not ready to be unplugged. And many of them are so inured, so hopelessly dependent on the system, that they will fight to protect it.”

Morpheus, The Matrix (1999)
