CrunchBang is a Debian GNU/Linux based distribution offering a great blend of speed, style and substance. Using the nimble Openbox window manager, it is highly customisable and provides a modern, full-featured GNU/Linux system without sacrificing performance.

The primary aim of the CrunchBang project is to produce a stable distribution offering the best possible out-of-the-box Openbox experience. To achieve this goal, CrunchBang pulls many base packages directly from Debian's repositories, which are well-known for providing stable and secure software. Packages from CrunchBang's own repositories are then customised and pinned to the system to produce what is known as the CrunchBang distro.
