The Live Systems project maintains the components to build Debian based Live systems and the official Debian Live images themselves.

A Debian Live system is a Debian operating system that does not require a classical installer to use it. It comes on various media, including CD-ROM, USB sticks, or via netboot. Why Debian Live?

Although the Live Systems project is about the tools to create your own customized Live system, we offer some prebuilt images. Currently, builds for four desktop environments GNOME, KDE, LXDE, and Xfce as well as the standard system and for rescue purposes are available.
