I've built similar functionality using Hammerspoon, configuration described at http://simonduff.net/hammerspoon/

However, I normally find myself lazy, and normally end up using the trackpad to drag windows to corners and edges to resize (also built with Hammerspoon)

Interestingly enough, AppGrid started out as my custom Slate configuration. But I know there’s something to be said for the convenience of not having to configure anything, and having an app Just Work[tm]. Even after I created Zephyros and Hydra and Mjolnor, I always come back to just using AppGrid for its simplicity.

Oh wow, I've just realised your that Steven Degutis, author of Mjolnir, of which Hammerspoon is based!!!

Any reason you've built a stand-alone app for this, given Mjolnir (and Hammerspoon) can do this pretty easily?

Coincidentally I answered this in a sibling comment at the same time you asked. Long story short this doesn’t require configuration and is pretty lightweight.
