DietPi
Minimal Debian OS optimised for single-board computers
DietPi is a lightweight, Debian-based operating system for single-board computers and other low-power devices. It provides a minimal base image designed to keep CPU and RAM usage low, with RAM logging enabled by default. The system addresses the need for a small, efficient foundation that can be configured and maintained without extensive manual setup.
DietPi includes several menu-driven tools: DietPi-Software for installing and optimising ready-to-run software packages, DietPi-Config for hardware and software settings such as network and localisation, DietPi-Backup for system backup and restore, and DietPi-Update for applying updates without rewriting the image. Additional modules include DietPi-Services Control for adjusting process priority, nice, affinity and scheduler settings, and DietPi-Automation for unattended installation configured through dietpi.txt. Logging can be handled through DietPi-RAMlog, rsyslog or logrotate. DietPi-Benchmark provides CPU and IO comparison results for supported hardware.
DietPi is aimed at users running Debian on supported single-board computers and low-power devices, including Raspberry Pi, Odroid, PINE64, Radxa, ASUS NanoPi, Orange Pi, RISC-V and PC/VM targets. Images are available for Debian 13 stable, with Debian 12 and Debian 14 also offered. The project is distributed as downloadable images; no paid editions, trials or seat-based plans are described.
