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
