Tiling Window Manager !link! -
TWMs are incredibly lightweight. While a full desktop environment like GNOME might use 800MB to 1GB of RAM at idle, a TWM like i3 or dwm often uses less than 50MB. This makes them ideal for older hardware or squeezing every drop of performance out of a workstation.
A tiling window manager (TWM) is a piece of software that automatically arranges windows on your screen so they don't overlap. Unlike traditional "stacking" window managers—like those found in Windows, macOS, or standard Linux desktops (GNOME/KDE)—a TWM treats your screen real estate as a precious resource, filling every pixel like a mosaic.
