Horizon64 is a hobbyist operating system designed for the x86_64 architecture. It was originally booted with a custom bootloader called sunrise, which was developed for the i686 architecture. Horizon64 has since been refactored to operate in 64-bit mode and now is booted with the limine bootloader.
