Ribbon is the BetterSnapTool alternative for most people who are tired of placing every window. New columns join a strip and keep their width. Keep BetterSnapTool for custom snap areas you already drew. Rectangle, Moom and Amethyst cover free snapping, saved layouts and free tiling.
TL;DR
| Need | Start with | Main limit |
|---|---|---|
| Windows that keep their width | Ribbon | Apple silicon, macOS 14+, no trial |
| Custom snap areas you already configured | Keep BetterSnapTool | Paid, manual placement |
| Free halves, thirds and quarters | Rectangle | Fixed actions in free app |
| Halves and quarters, no install | macOS tiling | macOS 15+, no thirds |
| Saved workspaces and custom targets | Rectangle Pro | $9.99, 10-day trial |
| Saved arrangements and chains | Moom | $15, free trial |
| A radial menu | Loop | Different input model |
| Automatic layout, not snap zones | Amethyst | Windows share the screen |
BetterSnapTool alternatives fall into two groups: tools that still let you place windows, and tools that take over the arrangement. The first group is the closer replacement. Start there unless manual snapping is the thing you want to remove.
Ribbon
Ribbon keeps windows in a scrolling strip. New columns join without shrinking the others. Each display has its own strip within native macOS Spaces. ⌃⌥R sets the focused column's width; the others keep theirs.
The price is $17 once for one Mac, $39 for three and $59 for five.
Good to know: Ribbon needs Apple silicon and macOS 14 or later, and there is no free trial. It does not import custom snap zones. The browser demo shows the keys.
Don't replace BetterSnapTool to save money you already spent
BetterSnapTool is $1.99 on the US Mac App Store and requires macOS 12 or later in the current listing. It supports keyboard shortcuts, edge and corner snapping, and custom snap areas.
If you already own it and the areas work, another one-time purchase doesn't lower your costs. Make a list of the missing actions before switching. Don't confuse BetterSnapTool with BetterTouchTool, the same developer's wider automation app.
Rectangle, for free fixed-position snapping
Rectangle is free, MIT licensed and supports macOS 14 or later in its current version. It moves windows with keyboard shortcuts or edge snap areas, including thirds and two-thirds. Repeating a shortcut cycles sizes.
Choose it if your BetterSnapTool setup is mostly halves, thirds and quarters. It isn't an import path for your hand-drawn snap areas. Before leaving a custom 25/50/25 arrangement, check the exact actions you need. Rectangle alternatives compares the next step beyond its free version.
macOS tiling, if your needs are basic
On macOS 15 Sequoia or later, you can snap windows to halves and quarters without another app. Use the green-button menu or drag to edges and corners. Fn⌃← and → place a window in a half. Fn⌃⇧← places two windows side by side.
The missing pieces are thirds, custom snap regions and saved layouts. If you don't need them, built-in is a good outcome. How to split screen on Mac shows the steps.
Rectangle Pro, for custom targets and saved workspaces
Rectangle Pro adds custom snap targets, saved layouts, display-triggered arrangements and window throws. It is $9.99 after a 10-day trial, with one licence active on three devices. It requires macOS 13.5 or later on Intel or Apple silicon.
Pick it if custom regions are not enough and you want to recall a desk arrangement too. The trade-off is more configuration, not less. No BetterSnapTool area import is promised here.
Moom, for actions you chain and reuse
Moom saves window layouts and has custom snap zones, chains and a keyboard controller. It is $15 direct, with a free trial, for macOS 10.13 and later.
It fits a repeatable desk: editor here, browser there, terminal below. It is more app than you need just to snap left and right. Moom alternatives compares that workflow rather than mixing it with automatic tiling.
Loop, if input is what you want to change
Loop is free and GPL-3.0, macOS 13 and later. Hold a trigger key and point through a radial menu. The preview tells you where the window will go.
Choose it if dragging to a distant screen edge is the annoyance. Don't choose it expecting your BetterSnapTool custom areas. Loop alternatives goes deeper on input styles.
Amethyst, if placing windows is the whole problem
Amethyst is free automatic tiling with a settings window. It keeps windows in layouts such as Tall and Wide and uses native Spaces. When a window opens, the others make room. Good if you want them visible; less good if a laptop screen makes them too narrow.
Before you change apps
- Record the custom areas you rely on, especially on external monitors.
- Quit BetterSnapTool while comparing another window manager.
- Check the laptop alone and with your usual displays attached.
- Compare actual actions, not claimed feature counts.
- Keep BetterSnapTool if the alternative only reproduces what already works.
