I use Divvy (https://apps.apple.com/us/app/divvy-window-manager/id4138575...).

It's probably the simplest one. Draw the shape you want on a grid, assign a global hotkey to each shape (fullscreen, top half, bot half, left, right, etc.), press the hotkey to move current window into that shape. Press the same hotkey again to move it between monitors.

It's funny how you get so used to your own dev environment and all the global hotkeys you might have and then completely take it for granted until you use a computer with it.

For macOS? I no longer use have any Macs in use, but I used yabai when I did.

On Linux I use i3.
