Welcome to the official documentation of MOS.
MOS is a lightweight operating system based on Devuan, designed specifically for small, energy‑efficient home servers.
The primary goal of MOS is to provide a simple, reliable, and low‑overhead platform for self‑hosting, virtualization, and homelab environments.
This project started as a personal solution, and at some point I decided to release it publicly to see if it resonates with others. MOS is still evolving, but the core ideas are already in place.
This documentation guides you from first installation to advanced system configuration and migration scenarios.
MOS is and will always remain fully open source.
No data is collected. There is no telemetry, no tracking, and no usage reporting of any kind. Everything runs locally and stays fully under your control.
MOS is intended for:
- Homelab users
- Self‑hosters
- Developers
- Anyone looking for a minimal, efficient server OS with modern tooling
