I'm looking for a lightweight way to snap windows in Lubuntu. It's possible to install
compiz, but doing so will make the system far less lightweight. Are there any alternatives or workarounds?
Using a lightweight window manager
You could use the lightweight compositing manager used by XFCE called xfwm4
This will give you basic windows snap.
N.B. if you dont like the default "change workspace when dragging a window off the screen" capability then untick the very last option shown in the picture.
Getting Tiling to work
However - if you want the "tiling-snap" of compiz you will need to get your coding-hands dirty because this is work-in-progress.
Through the following Q&A I have packaged this tiling patch into my PPA - instructions for installation can be found in the linked answer.
There is a great you-tube video showing this in action.

I personally use quicktile: https://github.com/ssokolow/quicktile
It allows you to snap windows in different regions of your screen based on keyboard inputs (e.g. ctrl+alt+1 to get the window to the top-left corner). It can be run as daemon on any X11-based desktop and only requires python as a dependency.
As far as I can tel, it does not have a drag-and-snap function, but your question did not seem restricted to mouse-only behaviour.
Super + arrow
This works for me, Super_L or Super_R, does not matter.
The up and down arrows split the screen horizontally.
