Blurred is a free, open-source Mac utility that automatically darkens every window except the one you are actively working in, eliminating visual clutter and sharpening focus without any configuration ceremony.
What is Blurred?
Blurred is a lightweight menu-bar app that applies a real-time dimming overlay to all inactive windows on your Mac display. The moment you click away from a window, everything behind it retreats into the background — not hidden, just visually subordinated — so the active surface always reads as the obvious thing demanding your attention.
It was built by the team at Dwarves Foundation and lives on GitHub as a genuinely free, no-subscription tool. There is no onboarding wizard, no account, and no settings screen to fight with. You launch it once and it quietly disappears into your menu bar, doing its job invisibly.
What does Blurred do best?
Blurred excels at one narrowly defined thing — passive attention management — and it does that thing extraordinarily well. Unlike full-screen mode, which bulldozes your workspace into isolation, Blurred keeps every window in peripheral view. You can glance at Slack, confirm your calendar event is still there, and still feel the pull of your primary task. The dimming intensity is adjustable, so if you find the default too aggressive or too gentle, a single slider corrects it.
Where this shines most is on large or ultra-wide displays. When you have a 27-inch monitor covered in browser tabs, a terminal, a Figma board, and a notes app all jostling for equal visual weight, Blurred imposes a clear hierarchy the moment your cursor lands anywhere. I find it particularly effective during writing sessions — the dim effect makes my draft feel like the only document that exists.
It also pairs naturally with apps like Mimestream or Tot that you keep open as glanceable references. They stay visible without competing for the eye.
Is Blurred free?
Yes — Blurred is completely free to download and use, with no in-app purchases, no premium tier, and no usage limits. The source code is publicly available on GitHub under an open-source license, so you can inspect exactly what it does before trusting it with your screen. Because it is community-maintained rather than backed by a subscription, updates depend on contributor activity rather than a commercial roadmap.
Who should use Blurred?
Blurred is ideal for anyone who keeps many windows open simultaneously and struggles to stay anchored to the task at hand. Writers, developers, and designers working across multiple tools will feel the benefit most acutely. If you already rely on focus tools like HiDock, Lungo, or Mela and you want something that addresses the visual layer rather than timers or blockers, Blurred fills that gap neatly.
It is less compelling on a 13-inch laptop where you tend to work in a single maximized window anyway, or if you habitually use Stage Manager — Apple's own layering system partly addresses the same problem, though Blurred's dimming approach feels more analog and less disruptive to window layout.
What are the best Blurred alternatives?
The closest direct alternative is HiDock's focus layer feature, though that is bundled inside a Dock replacement rather than offered standalone. Mango 5Star includes a similar window-highlighting mode. For a more radical approach, Hep can hide all other apps entirely, while macOS's own Stage Manager groups windows spatially instead of dimming them. None of these free alternatives match Blurred's combination of simplicity and surgical precision — install, adjust one slider, done.
If you want a paid, more feature-rich workspace manager, Mosaic or Mango 5Star are worth exploring, but they solve a broader problem. For pure passive dimming, nothing matches Blurred's minimal footprint.
How does Blurred compare to macOS Stage Manager?
Stage Manager, introduced in macOS Ventura, groups windows into sets and physically relocates inactive groups to a sidebar strip. It imposes a layout restructuring that many power users find intrusive. Blurred does no such thing — your windows stay exactly where you put them; only their visual prominence changes. The two tools can coexist, but they operate on different philosophies: Stage Manager reorganizes, Blurred just dims. For people who have spent years mastering a precise window arrangement, Blurred is the far less disruptive choice.
