DietPi is a Debian-family Linux distribution based on Debian. Extremely lightweight, optimized Debian minimal OS for single-board computers and homelabs.
Strengths: 1-click menu installs for Nextcloud, Pi-hole, Plex, Home Assistant; RAM logging prolongs micro-SD card life; Ultra-small footprint (<50MB RAM idle). Trade-offs: Text-based console wizard setup (not for GUI beginners).
