Debian based lightweight Linux operating systems

Lightweight operating systems are helpful to revive old computers, including desktops and laptops. It consumes very less CPU and RAM resources. Lightweight operating systems are often powered by window managers such as IceWM, JWM, and Fluxbox. They require significantly less RAM and CPU power than popular desktop environments like GNOME or KDE. Such systems can enhance the performance of the less powerful machines. The Debian operating system does not consume too many hardware resources. Here is the list of such Debian-based operating systems. 

AntiX Linux is a very slim operating system that consumes only 250 MB of RAM to run. It's systemd-free, instead using lighter init systems like SysVinit or Runit, and it makes minimal resource usage and fast boot times.  AntiX also comes in different "flavours" (Full, Base, Core, and Net) with varying levels of pre-installed software. The "Core" and "Net" versions are extremely minimal.

CrunchBang++ uses the Openbox window manager and makes use of significantly fewer system resources.

BunsenLabs Linux Boron is another slim operating system that uses the Openbox desktop.

Slax Linux is a slim operating system with a modular design and a lightweight desktop, which are its highlights. The core system is kept minimal, and users can add or remove software by simply adding or removing "modules".

MiniOS is an active, lightweight operating system project. XFCE and FluxBox-based desktops are available to download.

Debian LXDE and XFCE desktops also make a small footprint on hardware resources. The previous versions of Debian Linux (e.g. Debian 10, 11) were also fast due to their legacy kernels. Those who like vanilla Debian flavour, try the native Debian installer or Live DVD to experience a feather walk.
