There are many alternatives for Mac suggested here, but I'd like to share an alternative for Win too, Windowgroomer: https://github.com/aarmea/WindowGroomer
It's stale but works perfectly on win10, has just what I want from it. Secretly, I'm suggesting it here kind of hoping someone around here likes it as much as I and feels like contributing (since I'm not very good at the Windows stuff). A great contribution would be to be able to use keyboard to set the grid, not just the mouse. That said, I've been using it a long time and it works great.
I highly recommend Slate (https://github.com/jigish/slate). It doesn't appear to have some of the features of Moom, but it's quite adept and configurable.
https://www.spectacleapp.com but whose to say that won't disappear as well...? Software licenses are starting to feel dangerously close to "patenting the wheel".
