In the age of Raspberry Pis, home servers, and DIY projects, not every operating system is designed with minimalism in mind. Many default Linux distributions are bloated, resource-hungry, or simply not optimized for the limited resources of single-board computers (SBCs). That’s where DietPi shines.
DietPi is a lightweight, Debian-based OS optimized for speed and simplicity, designed specifically for low-powered devices. Whether you’re setting up a headless server, a Pi-hole DNS filter, or a retro gaming console, DietPi makes it easy, efficient, and fast.
🌿 What is DietPi?
DietPi is a highly optimized, minimal Debian-based OS tailored for single-board computers like:
- Raspberry Pi (all models)
- Odroid
- RockPro64
- Orange Pi
- NanoPi
- and even x86_64 systems like Intel NUCs or VMs
It’s engineered to run as lean as possible — with minimal background services, small disk and RAM footprint, and a highly automated setup process.
