Twister OS is a Linux-based operating system developed by Pi Labs for the Raspberry Pi series of single-board computers. A version for x86-64-based personal computers was released shortly after the initial Raspberry Pi release. The operating system is based on Raspberry Pi OS Lite and uses the Xfce desktop environment.
Twister OS is intended to provide a general-purpose computing experience with a visual style that evokes familiarity with other operating systems. It includes themes that resemble those of various versions of Microsoft Windows and macOS. Variants of Twister OS have been developed for different hardware platforms, including ARM-based systems with RK3399 processors.
