LemonOS is a hobbyist UNIX-like 64-bit operating system for x86_64 written in C++, featuring its own modular kernel with SMP and networking, a window server/compositor (LemonWM), and a set of userspace applications. It includes an Ext2 filesystem, IDE/AHCI/NVMe drivers, dynamic linking via mlibc, and ports such as Python 3, LLVM/Clang, and DOOM.
Use cases
- run a small unix-like desktop OS in QEMU
- learn operating system development from a real codebase
- experiment with a from-scratch C++ kernel
- study how a window server and compositor work
- test a hobby OS on x86_64 hardware
- explore osdev with SMP and networking support
When to choose
- You want a readable, from-scratch hobby OS codebase for learning or contributing to osdev
- You want to boot a lightweight UNIX-like GUI operating system in QEMU/KVM or on supported x86_64 hardware
- You want a playground for experimenting with kernels, drivers, or window server internals
When to avoid
- You need a production-grade, secure operating system for daily use, servers, or mission-critical workloads
- You need broad hardware support, a large package ecosystem, or long-term support
- You need Linux binary compatibility or POSIX certification
