ABOUT instantOS is based on Arch and maintains full compatibility with the Arch-Wiki and AUR. It uses a custom window manager with a bunch of facilitating custom software to provide an experience similar to a desktop environment but as powerful and fast as a window manager. In fact, all pieces being made for each other allows things that wouldn’t be possible by just editing dotfiles. It also has its own installer instantARCH
SUCKLESS instantOS is not a suckless distro. instantWM, intantLOCK and instantMENU started out as suckless forks, but contain less than 40% original suckless code and go into different directions. For instance, programs that are under 40kb should not put storage at such a high priority. Stability, features and speed are more important.
