Natively on Ubuntu Budgie, but if you don't mind setting up manually, it should work on all window managers that support the dependencies (not wayland): WindowShuffler
It can be used both via GUI as well as via (basic) keyboard support.

I found Shell Tile to be a pretty good alternative for Gnome. However, it isn't as clean as Mosaic.
What about gTile? It's quite flexible to configure (supports a variety of customizable grid sizes) and supports multiple monitors. You bring the window you want to to apply tiling to focus and manage it through the dialog pop-up with keyboard shortcuts or with the mouse.
I only use Linux so I never heard of Mosaic, but it looks impressive, Shell Tile on the other hand did not look like what I wanted when I tried it. Should I give it another try?
