Raspberry Pi OS is the official operating system of the Raspberry Pi line, maintained by Raspberry Pi itself and previously known as Raspbian. It is built from Debian, tuned for the Pi's ARM processors and modest memory, and ships in several forms: a Lite image that boots to a console for servers and embedded projects, and desktop images built around a lightweight, purpose-made environment with sensible defaults and beginner-friendly configuration tools such as raspi-config. The system integrates the Pi ecosystem's essentials, including GPIO programming libraries and first-party utilities for imaging and settings, and it benefits from an enormous body of tutorials written specifically against it. Education and hobby electronics remain its heartland, though plenty of small servers run it quietly for years. OpenFactory can emulate a Raspberry Pi in your browser and provides direct image downloads, so you can explore the desktop before buying a board.
