Layout that maintains itself
Auto Flow arranges managed windows into layouts with split or tab priority, so the arrangement holds as new windows open. Moom's placement and saved layouts apply at the moment you invoke them.
Moom is a Mac window placement app from Many Tricks that puts a palette of sizes and positions behind a window's green button and can save whole window layouts. Tangrid is a macOS window manager that places windows as well, and also keeps a layout arranged and helps you find a window again. Both products can restore an arrangement, so the choice comes down to how the arrangement is built.
In short
Both products place windows and restore saved arrangements, so the table compares those two modules.
| Module | Moom | Tangrid |
|---|---|---|
| Window snapping | Yes A pop-up palette on the window's green button, a custom grid, configurable snap zones, and keyboard shortcuts, with actions that can be chained and organised into folders. | Yes Snap Assistant places a window in any of 18 positions on a 3x6 grid, fills the screen, and supports modifier-based moving and resizing. |
| Workspaces | Yes Saved layouts restore an arrangement when you activate them. A layout can be tied to the apps you use, or move the most recently used windows regardless of which apps they belong to. | Yes Workspaces save a named project layout, including positions, sizes, tiled or floating state, tab groups, and the target desktop, and can reopen missing windows when launch actions are configured. |
Tangrid covers these modules too.
Auto Flow arranges managed windows into layouts with split or tab priority, so the arrangement holds as new windows open. Moom's placement and saved layouts apply at the moment you invoke them.
Window Switcher lists every window or only those of the current app, with previews and vertical search by window title or app name. Dock Preview shows an app's windows when you hover its Dock icon.
Tab Grouping puts related windows into one tabbed slot in the layout, with previews, reordering, and whole-group moves, swaps, and merges.
Yes. Arrange your windows the way you want them, save the layout, and activate it later to restore that arrangement. Moom can associate a layout with specific apps, or move the most recently used windows into the saved positions independent of which apps they belong to.
No. Moom acts when you use the pop-up palette, a snap zone, the grid, a keyboard shortcut, or a saved layout. Keeping managed windows arranged as the desktop changes is the job of Tangrid's Auto Flow mode.
You can, but the placement and saved-layout features overlap. Snap Assistant and Workspaces cover similar ground, so most people turn off the duplicate shortcuts or choose one tool for placement.
Tangrid adds Auto Flow automatic layouts, Tab Grouping, Window Switcher with vertical search, Dock Preview, and a Space Indicator. Moom covers placement, custom grids, snap zones, and saved window layouts.
