About serenity
SerenityOS is a graphical Unix like operating system built for 64 bit x86, Arm, and RISC V computers. It is written in C++ and released under the BSD 2 Clause license, and it lives in the open source operating system ecosystem alongside other hobbyist and research kernels. The project describes itself as a love letter to 1990s user interfaces paired with a custom Unix like core, aiming for a marriage between the aesthetic of late 1990s productivity software and the power user accessibility of late 2000s Unix systems.
