## What it is
ToaruOS is a complete, independent hobby operating system for x86-64 PCs and ARMv8 VM environments, built entirely from original code with no third-party runtime dependencies. It includes an SMP-capable modular kernel, a C standard library with dynamic linker, a composited desktop environment, the Kuroko bytecode-compiled language, and a suite of POSIX utilities.

## Use cases
- study how an operating system kernel is built from scratch
- explore a from-scratch composited desktop environment and window manager
- learn OS development with a real, bootable codebase
- run a self-contained POSIX-like OS in a VM
- examine a dynamic linker and C library implementation
- try the Kuroko programming language and Bim editor in a self-hosted OS

## When to choose
- you want a complete, dependency-free OS codebase to read, build, and modify
- you are learning kernel, compositor, or libc internals from working code
- you need a hobby OS that runs on x86-64 and aarch64 VMs

## When to avoid
- you need a production-grade OS with broad hardware support
- you require full POSIX compliance or a mature package ecosystem
- you want to run everyday desktop applications

## Facets
- artifact type: application
- maturity: active
- function: interpreter, compiler, gui, terminal-ui, editor, programming-language
- domain: operating-systems, developer-tools, graphics
- platform: windows, cross-platform
- tags: operating-system, kernel, osdev, compositor, window-manager, bootloader, libc, smp, x86-64, aarch64, armv8, baremetal, hobby-os, self-hosted, linux, macos
