FrankenWM is a small, dynamic tiling window manager for Xorg. It is written purely in C and configured using a header at compile-time. It has been forked from monsterwm ages ago, and while the configuration and usage still feels a lot like monsterwm, the underlying code is almost a complete rewrite. It is also used on the asynchronous XCB library as opposed to the synchronous Xlib, which monsterwm is based on, which makes it even faster.

Here is a quick overview of the features it brings:

i could never really get into tiling window managers
im sure they make people efficient as fuck, but i like my dynamic wm
i spent way too much time configuring them, anyways. the only one i enjoy using is frankenwm
