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.
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.
This site is used to guide users in the choice of devices, and to guide people towards the best choice.
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 BananaHackers Manifest

KaiOS must not die (this is the cry of a fire fox that wants to rise again)

I've seen and tried everything from our community's open source projects: I made a free phone call using a prototype of a SIP client, from Italy to Ukraine in January 2019 (Batty app by LuxFerre, still in alpha). I played Super Mario and other GameBoy Color games (I'm not much of a gamer, but many are using the KaiBoy app right now) on my Nokia 8110 4G. I met the first developer from France (Sylvain) who adapted WeboGram, a working client for Telegram in late 2018 on KaiOS, still not available on the KaiStore, and we were the first to use WhatsApp outside of India, five months earlier (December 2018) of the official release on KaiStore (May 2019), when everyone considered KaiOS a rip-off (a year of promises to release the application globally, and a long waiting, rich of disappointment, from everybody).
With this I just want to emphasize how simple and malleable KaiOS is. I love KaiOS! All BananaHackers love KaiOS! Everyone who follows us has learned to love KaiOS!
All the applications of the operating system are basically websites in offline version, the "webapps", and the ever increasing number of developers for this sector is constantly growing.Web development is something within everyone's reach, as the programming language is simple, unlike Android apps. For example, WhatsApp for KaiOS weighs around 700 KB, while the Android version over 25 MB. Few lines of code and files to compile. Less work for more experienced developers. More opportunities for everyone to learn.KaiOS could use all this to its advantage, but the KaiStore is the only officially recognized way to transfer new apps and services to these devices, and at the same time it's also a hindrance to itself.The applications loaded on the KaiStore are mainly dedicated to games and entertainment, but there are also applications classified as "utilities", that should improve the efficiency of these phones. Utility that vanishes every time appear the KaiAds, the advertisements, the only earning opportunity that KaiosTech offers to new developers.That's right, everyone deserves to be recognized for their efforts and all the work they've done, but unfortunately these advertisements penalize what the user experience is, on these small screens.
Those who buy a KaiOS device are looking for simplicity, without too many sacrifices.
So if it's so easy to develop webapps, why is the KaiStore so full of mostly useless apps?The truth is that there are some projects that are rejected by the KaiStore, as they do not respect the upload rules. At KaiosTech, developer portal moderators are constantly working to enforce standards. The demand is high, also thanks to the push of the company that wants to convince developers to insert many more ads in their apps, allowing them to monetize.Implementing advertisements can help you earn money, but penalizes the actual use of these applications. On a 320x240 resolution screen all you need to focus on is usability, and KaiOS devices have this kind of display.
KaiosTech should focus more on the quality of its product, rather than worsening its usability.
There are other ways to make money with webapps, for example through donations, at least with free and open source software. This experiment is underway with our new third-party app store, created to permanently replace the B-Hackers Store: the BananaHackers WebStore ( , also accessible from the main page of our site, A developer can also feel free to add a PayPal link within their app and on the site page, for anyone who wants to offer them a donation, and there is also the option to add screenshots to preview the content of the application. But what matters most is the developer's sense of accomplishment towards the open source community.
I would like more cooperation from KaiosTech itself.
We know very well the hidden potential of KaiOS, but as long as it remains hidden, closed by the limitations imposed by KaiosTech for reasons of commercial partnership with its major investors, KaiOS will always and only remain the parody of an operating system for mobile devices, and consequently not will never, ever compete with Android and iOS.KaiosTech should review its rules on allowed uploads, for example by adding OmniSD to the KaiStore and thus also delegating the sideloading of third party apps to external sources, thus generating more interest.
KaiosTech, I'm writing to you and all your brilliant developers: do we all want to bring KaiOS to the fore? Mozilla, creating Firefox OS, left you a huge heredity!
Many functions that we, BananaHackers, have discovered through external research, on our own, are all things that already existed in the operating system itself!
So, wake up folks! KaiOS must be in the place it deserves!Why waste this opportunity? Let us make the most of the potential of web applications!
Allow free and open source projects to enter the KaiStore, giving everyone the opportunity to grow the operating system! Telegram, emulators, applications for VoiP ... these are just some of the many things I have seen and tried together with the members of the BananaHackers community, and which have made KaiOS a very special operating system, the best among mobile devices! In my eyes and in the eyes of those who follow us. And you know it well!
There are hundreds of users here looking forward to a real breakthrough from you! Come on!

Freedom is a right! In the case of software it is a choice! And we want KaiOS as first choice!


That's why I decided to write this Matrix-themed site

From the first day I published this site, I wanted to include on the homepage the famous words of Morpheus, from the movie, in which he explained to Neo what the Matrix is:
“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.”
Perhaps it was a coincidence that the release the Nokia 8110 4G, device inspired by the one from The Matrix movie, the "bananaphone", was the key to starting such a deep and engaging research, to the point of inspiring the birth of a community of users that now has hundreds of subscribers from all over the world. The same community that is ready to reveal the true power of an operating system born from the ashes of Firefox OS, a privacy-oriented system that died under the overwhelming power of two giants who command the global mobile market, Android and iOS, feeding on data from billions of unwitting users hypnotized by those large touch screens... or maybe not? I like to think that we followed the "white rabbit", like Neo, in the movie, in search of the truth. I don't really know how, but I like to think so.
Again, I can quote some dialogues from the movie:
Morpheus: Do you believe in fate, Neo?
Neo: No.
Morpheus: Why not?
Neo: Because I don't like the idea that I'm not in control of my life.
Morpheus: I know exactly what you mean. Let me tell you why you're here. You're here because you know something. What you know you can't explain, but you feel it. You've felt it your entire life, that there's something wrong with the world. You don't know what it is, but it's there, like a splinter in your mind, driving you mad. It is this feeling that has brought you to me. Do you know what I'm talking about?
Neo: The Matrix.
Morpheus: Do you want to know what it is?
Neo: Yes.
Morpheus: The Matrix is everywhere. It is all around us. Even now, in this very room. You can see it when you look out your window or when you turn on your television. You can feel it when you go to work... when you go to church... when you pay your taxes. It is the world that has been pulled over your eyes to blind you from the truth.
Neo: What truth?
Morpheus: That you are a slave, Neo. Like everyone else you were born into bondage. Into a prison that you cannot taste or see or touch. A prison for your mind."
Maybe I'm crazy, but the people around me seemed too oblivious to what was happening to them.People let themselves be conditioned by alarmist and mostly false news. A taste of shit between a video of kittens playing and a culinary recipe, to influence people's decisions much faster, tacitly.What better way to shape people's habits than to monopolize the mobile phone market with smartphones? Thanks to their large screens, they collect all the attention of individuals. The result is under the eyes of the most attentive people: a digital zombie apocalypse!I've always hated that type of device, orienting my purchasing choices towards simpler and less distracting phones. In my obsessive search for truth, I realized that my country was drowning in indifference and individualism. I just had to look around and saw ninety percent of people staring at their smartphone displays. The ninety percent of people around me, every day.
Maybe because I repudiated social media, but years of absence from the internet, the promotions that are becoming more accessible to most operators have always kept me away from the old interaction through calls and SMS. I don't trust these services that are too fast and cold, capable of depriving the person of the ability to interact with others and socialize live.KaiOS was proposed as a means of initiating a digital detox and, in a way, working on it to make it interesting, has dragged me into a mood very similar to the one I'm trying to fight.
However, there is a beginning and an end to everything, and even smartphones will start to bore people sooner or later. It's just a matter of time... or fashion. Manufacturers just need to find a way to grab the attention of the public, and right now the new trend is foldable smartphones (a luxury for a few).Perhaps the future will see us locked up in a digital prison, in which everything will be beautiful, apart from the fact that it will still be a prison, ready to cover the degradation in reality, fueled by people's indifference, as is already happening by some years in my city, still in the smartphone's hera.
In the meantime, with this site, I try to do my part in history, going against the tide and supporting a community of enthusiasts who choose simplicity in technology. A simplicity with great potential, in an attempt to save as many people as possible from digital intoxication.
And again, as Neo said in the movie:

"I don't know the future. I didn't come here to tell you how this is going to end. I came here to tell you how it's going to begin. I'm going to hang up this phone, and then I'm going to show these people what you don't want them to see. I'm going to show them [...] a world without rules and controls, without borders or boundaries. A world where anything is possible."

I think living is leaving something to those who remain, and although this is nothing special, I am happy to have helped so many people to find our resources, whatever my future will be in this community. Somehow I can say that I have helped someone smile, and I think that's the first thing to think about when choosing simplicity in your life.
