Lilith is a hobby x86-64 operating system with a POSIX-like kernel and userspace written in Crystal. It includes a garbage collector, FAT16 filesystem support, preemptive multitasking, and a simple window manager with graphical programs.

Use cases

  • experiment with an operating system written in Crystal
  • study a hobby x86-64 kernel implementation
  • run a small POSIX-like OS in QEMU
  • learn about preemptive multitasking and syscalls
  • explore a garbage collector in a kernel context

When to choose

  • you want to read or hack on an OS kernel written in Crystal
  • you need a small educational x86-64 OS to run under QEMU

When to avoid

  • you need a production-ready or well-supported operating system
  • you need broad hardware support or a stable ABI
  • you don't want to work with an experimental hobby project
