In the Linux world there is always movement, but I don't know if as much as now. New things are always appearing, but the fact is that, in recent years, we must add the development of mobile operating systems and their applications. A good example, the best for me, has been presented this year: the JingOS that can already be tested and that will be installed by default on the JingPad A1. A few days ago I wrote an article about the possibility that we will soon see jingde, and just today they started talking about cutefishOS, which still cannot be assured is related (Updated: confirm that they share components, but are different teams).
The project is very new, so much so that your forum It is empty and on their website they do not give much information about it. If we go to Twitter, yes we can see that it exists and can already be installed Spanish Sporthorse on Arch Linux, which is the desktop that the CutefishOS operating system will use. At the moment, or at least I have not found anything yet, they do not mention what they will be based on, but Manjaro has already released an "Unstable" version with CDE, and that is what you can see in the screenshot that heads this article.
Little is known about CutefishOS, but we can already test its desktop
I was a bit surprised to see the CDE interface. It is very similar to that of JingOS, which in turn looks a lot like iPadOS. Like JingOS, Cutefish has created a group of applications that look good on your desktop, but it is so similar to what we have seen in JingOS that, together with the little information they have provided, all are doubts. It is known to use some KDE software, like KWin or Kate.
In the official website they say it will offer an enhanced Linux experience that will be built on solid Linux like a rock, but they say no more. Considering that Manjaro has been the first to promote it, it is easy to think that it will be based on Manjaro or directly on Arch Linux, and more if we consider that CDE is already in the Arch repositories.
CutefishOS is not available for download at the moment, but you can try CDE at Manjaro Cutefish, something that I am doing right now in GNOME Boxes and I can only say that it goes very fast. To know more details we will have to wait for the developer team to offer more information.
