oh damn this is incredible, this idea is what I always wanted, I prefer that over Niri and Niri support for macOS is not where to my liking (I tried a few and they're all clunky and/or don't support multiple displays nicely)
$80 for a window manager (or $24 / year) ... yeesh. Maybe I will try it when I get fed up with rectangle.
Holy crow! Divvy was like $15 for life.
If you like this idea, also check out aerospace, a full on window manager for macOS.

I've been using it for a couple of years now, and it's great. You can navigate between windows with the keyboard, etc etc.
Like everyone else, I love Divvy and am sad it's been orphaned. I'll check this out!
I've been using Divvy for many years and am gutted that it seems to have been orphaned and won't be updated for apple silicon. I ended up switching a few months ago to Lasso, which does most of what I want. But I miss Divvy.

Had been a fan of Rectangle until I re-discovered for myself a regular mouse (the one with a scroll-wheel and real buttons) on mac. Now I'm using "Easy Move+Resize", which replicates the linux experience of cmd+left-click-drag and cmd+middle-click-drag for moving and resizing windows.
I've been on Divvy for years, and on the latest OSX I'm noticing some issues. It seems completely unmaintained.
I was looking into alternatives, either free or paid or just making one myself... so this is good timing.
Expect a contribution from me soon, I already see one missing feature I need! :-)
My solution to wanting a better window snapper - really I just wanted Windows style left, center (full) and right docking with specific keyboard shortcut ala windows was just to modify Rectangle to get of most of its feature and changes the shortcuts and behaviour a little.
I also loved Divvy, but it recently started to make the little 'preview' desktops /spaces in Mission Control go blank. Looking for an alternative, I found Moom, which works also great. I can recommend that, too!

Looking good, a bit outside of scope of what I needed but I can totally see the appeal! Good luck!
I used and loved SizeUp until upgrading laptop and MacOS from 15 to 26, now most features don't work or are buggy, especially moving windows between spaces, desktops or sceens. Will be giving GridSnap a go asap.
Haven't tried it myself, but some apps lag horribly on resize. Seeing how this app immediately resizes them as you drag across the cells, wouldn't this end up horrible for some of those apps?
I haven't encountered that so far, and have been using it for a few weeks now, but am happy to receive any bug reports!
I do use it on M4 Pro though, so that is certainly a possibility!
Seriously why did divy never recompile for arm64?
I recently came across Divvy (https://mizage.com/divvy/), and since it's closed source and hasn't changed in years, I built a lightweight open source alternative with Claude Code.
Press a shortcut, a grid appears, drag across the cells you want and the window snaps there, following your drag live. Any region can be saved as a preset with its own shortcut. It is simple Swift, has no dependencies, and requires no network access.
Tested on macOS 26 Tahoe. Feedback from anyone on earlier macOS versions is very welcome.
It's useful to me as is, and maybe it will be useful to someone else. Enjoy!
