Rectangle App for Mac: What It Does, Free vs Pro, and When to Upgrade (2026)

Rectangle is one of the best free Mac utilities — but it solves one specific problem. Here's an honest look at what the Rectangle app does, how free compares to Pro, and the one limit no paid upgrade can fix.

If you've asked anyone how to manage windows on a Mac, they've probably said "just use Rectangle." It's free, open source, and does exactly what it promises. After a few weeks with it, though, many users hit the same question: is this all there is?

This guide gives you an honest answer. What the Rectangle app actually does, how the free version compares to Rectangle Pro, where the tool genuinely excels, and the ceiling it hits — a ceiling that no paid upgrade resolves.

What is the Rectangle app?

Rectangle is a free, open-source window management utility for macOS, maintained by Ryan Hanson since 2019. It lets you move and resize windows using keyboard shortcuts or by dragging them to screen edges — snapping them to predefined positions like half-screen, quarter, thirds, two-thirds, and fullscreen.

The app lives in your menu bar, runs with nearly zero CPU overhead, and has no telemetry. Its code is public on GitHub under the MIT license. There is also a paid upgrade called Rectangle Pro, made by the same developer.

Rectangle replaced the older Spectacle app (discontinued in 2019), which worked on the same principle. Many macOS users who outgrew Spectacle migrated directly to Rectangle and have used it ever since.

Rectangle free: what's included

The free Rectangle app covers the window positions most people actually use:

All shortcuts are remappable. Snap-to-edge by dragging to a corner or border also works out of the box. Multiple monitor support is solid — windows move between displays with dedicated shortcuts.

For the majority of users who want to stop manually dragging windows to approximate positions, free Rectangle is a complete solution. There is no expiry, no nag screen, no feature limit that resets after 30 days.

Rectangle Pro: what you actually get for $9.99

Rectangle Pro ($9.99 one-time as of 2026, also available via Setapp) adds a layer on top of the free version:

Custom snap zones — instead of being limited to halves, thirds, and quarters, you draw arbitrary zones on a canvas. A 60/40 split, a three-column layout with different widths, an ultrawide arrangement with a narrow sidebar — anything is possible. This is the feature most people buy Rectangle Pro for.

Window cycling — press a shortcut repeatedly to cycle a window through a sequence of positions (e.g., left third → center third → right third). Saves needing a separate shortcut for each stop.

Multi-step shortcuts — chain actions with a single key combo for more complex positioning sequences.

Menu bar interface — a richer quick-access panel showing recent window actions.

App Store availability — Rectangle Pro is available on the Mac App Store; free Rectangle distributes only from its website (rectangleapp.com).

Free vs Pro: is the upgrade worth it?

Verdict: If you use standard snap positions and they cover your needs, the free version is complete — there is no meaningful pressure to upgrade. Rectangle Pro makes sense specifically if you need snap zones the standard grid can't express (unusual monitor aspect ratios, custom column ratios) or if you want window cycling shortcuts. For all other use cases, free Rectangle is genuinely the better value.

Where the Rectangle app excels

Rectangle does a narrow job extremely well. Three areas where it genuinely shines:

Zero-friction adoption. Install, launch, done. No tutorial required, no configuration file, no account. The default shortcuts match what users expect from similar tools on Windows and Linux.

Keyboard-first speed. Experienced users position windows without moving their hands off the keyboard. Once the shortcuts are in muscle memory, arranging a session takes seconds. Rectangle is significantly faster than dragging windows manually, even with macOS's improved tiling in Sequoia.

Trust and transparency. Open source with a clear MIT license means Rectangle's behavior is auditable. It has no subscription, no telemetry opt-out buried in settings, no upsell nag. For users who care about what software is doing on their machine, that matters.

The ceiling Rectangle cannot cross

Here is where honesty matters: Rectangle and Rectangle Pro share one fundamental limit. They only move windows that are already open.

This is correct behavior for a window manager. The problem arises when people start expecting it to do the job of a workspace manager.

Every morning (or every time you switch projects), you still need to:

1. Open your editor and navigate to the project directory
2. Launch the right browser and navigate to the right set of tabs
3. Open Slack and find the channel for that project
4. Open terminal and export the right environment variables
5. Only then — once everything is open — use Rectangle to snap things into place

Rectangle handles step 5 perfectly. Steps 1–4 are entirely on you, every single time. Restart your Mac or close apps overnight, and the next day begins from scratch again.

That limit is why many people who search for "Rectangle alternatives" aren't actually looking for better snapping. They've already learned Rectangle. What they want is a tool that handles the rebuilding they do before Rectangle even gets involved.

When you've outgrown window snapping

If the friction in your workflow is the ten minutes of setup before you can start working — relaunching apps, resetting browser identities, navigating to tabs and channels — you need a workspace manager, not a better snapper.

ShiftPlus operates at the layer above Rectangle. Where Rectangle positions windows that are open, ShiftPlus remembers entire project environments and rebuilds them from scratch:

• Apps — which ones to launch (and which to close from the previous project)
• Browser profile — Chrome, Safari, Arc, Brave, Edge — switches the active identity so cookies, logins, and history stay isolated per project
• URLs — not just tabs but deeplinks: a specific Slack channel, a Linear board, a Spotify playlist, a VS Code project folder
• Terminal environment — shell variables and AWS profile set automatically so AWS_PROFILE=client-a is ready without manual export
• macOS Spaces — each app placed on the correct Space, no dragging needed

Press the workspace hotkey. ShiftPlus closes or hides the previous project's apps, launches the new ones, switches the browser profile, opens the URLs, and arranges everything — typically in a few seconds. Rectangle, if you're still using it, then snaps individual windows mid-session.

They're not competing tools. Most ShiftPlus users who came from Rectangle keep both. ShiftPlus handles the project level; Rectangle handles fine-tuning windows within a session. There's no conflict and no duplication.

FAQ

Is Rectangle app free?

Yes. The core Rectangle app is free and open source under the MIT license. It is available at rectangleapp.com and covers all standard snap positions (halves, thirds, quarters, fullscreen, corners). Rectangle Pro is a separate paid upgrade for $9.99 that adds custom snap zones and window cycling.

Is Rectangle safe to use on Mac?

Rectangle is open source (MIT license), actively maintained, and has been downloaded by millions of Mac users since 2019. It uses macOS Accessibility APIs to move windows, the same mechanism used by macOS itself. It has no telemetry and no network requests. The source code is public on GitHub and can be audited independently.

Does the Rectangle app work on macOS Sequoia?

Yes. Rectangle is actively maintained and compatible with macOS Sequoia. Note that macOS Sequoia introduced its own basic window tiling feature — keyboard-triggered snapping to halves and quarters. Rectangle still offers more snap positions, full keyboard remapping, and a more predictable behavior model than the native implementation for most users.

What happened to Spectacle app?

Spectacle, an earlier open-source Mac window manager, was discontinued by its developer in 2019. The developer recommended migrating to Rectangle, which was built as a spiritual successor. Rectangle is actively maintained and has significantly more features than Spectacle had at the time it was discontinued.

Can Rectangle restore windows after a Mac restart?

No. Rectangle moves and resizes windows that are already open — it has no mechanism to relaunch apps or restore a previous session after a restart. For that behavior, you need a workspace manager like ShiftPlus, which saves your app layout and restores it on demand, including after restarts and across different Macs.

Is Rectangle better than Magnet?

For most users, free Rectangle is a better value than paid Magnet ($7.99) because it covers the same core functionality at no cost. Magnet's main advantages are Mac App Store distribution (easier to manage with Family Sharing) and slightly broader default shortcut coverage for ultrawide monitors. If you're already comfortable with Rectangle's shortcuts, there's no meaningful reason to switch.

ShiftPlus is free to try for 14 days — no credit card required. Download the trial if you want the layer above Rectangle: full project context switched with one hotkey.
