AltTab vs Contexts vs Witch macOS: Which App Switcher Should You Actually Install?

If you are searching alttab vs contexts vs witch macos, you have already done the hard work — you have narrowed the macOS app switcher field down to the three names every power-user roundup keeps citing. The remaining question is which of the three to actually install, and the honest answer is that none of them is universally best. Each one picks a different default for what a switch should feel like, and the right pick is the one whose default matches how your brain already moves between apps.

This page is a fair 3-way comparison, written by the people who built Manico. We have a horse in the race, so we will be transparent about that — Manico is a fourth option that picks a different default again. But the first three-quarters of this page are about AltTab, Contexts, and Witch on their own terms. If one of them is the right fit, install it and skip the buying section. We would rather you end up on the tool that matches your hands than on ours.

What AltTab does — and what it does not

AltTab is a free, open-source app that replaces the macOS Cmd+Tab with a Windows-style overlay. You hold the trigger, a grid of live window thumbnails appears, and you tap Tab to cycle until the right one is highlighted. Release the trigger and that window comes to the front. It supports macOS 10.12 and up, has a robust preferences panel, and costs zero dollars.

AltTab is the right pick if your previous machine was a Windows one and your hands already know that motion, or if you just want a free upgrade to Cmd+Tab with previews. The thumbnail grid genuinely helps when you have three browser windows open and need the one with the migration plan in it. The trade-off is that the switching unit is still the window and the selection method is still cycling — AltTab is a polished version of the system default, not a different paradigm.

If you have already tried AltTab and want a head-to-head with Manico specifically, the deeper page is Manico vs AltTab.

What Contexts does — and where it shines

Contexts is a paid app from a small studio that built a switcher around a persistent sidebar of open windows. You can trigger an overlay similar to AltTab’s, but the differentiator is the optional sidebar — a column down one edge of your screen that lists every open window across every app, all the time. You also get type-to-search inside the overlay, so you can narrow the window list by typing a few letters of the title or app name.

Contexts is the right pick if the sidebar idea actively excites you. People who pick Contexts tend to describe it as “I want a window inventory I can see without thinking about it” — and no other tool in this category offers that exact surface. The price is roughly $9.99/year or about $19 for a lifetime license, both fair for what is a deep, ongoing-maintenance product.

The trade-off is screen real estate (the sidebar takes a strip) and a more involved configuration story than the other two. If you want the head-to-head against Manico, that is Manico vs Contexts.

What Witch does — and why long-time Mac users keep it

Witch, from Many Tricks, has been in the pro-Mac toolkit for years. It is a window-level switcher built around a recency-ordered list. You hold a configurable trigger (Option+Tab is a common starting point), a small overlay appears with every open window across every app sorted by what you used most recently, and you scroll until you land on the one you want.

The thing that makes Witch worth its roughly $14 one-time license is not the visual style — that is more compact than AltTab and less ambitious than Contexts — but the granularity of the actions. Witch lets you bind separate hotkeys to next window, previous window, next window of the active app, previous window of the active app, and a few more. If you live in a sea of windows and want to mash a specific action without scanning, Witch gives you the verbs.

Witch is the right pick if you genuinely think in windows rather than apps and want a macOS-native tool with deep window-level controls. The head-to-head against Manico is Manico vs Witch.

Where AltTab, Contexts, and Witch agree

All three reject the cycling-through-apps-only model that ships with macOS. All three pick the window as the unit of switching. All three require Accessibility permission, are unsandboxed, and live in the menu bar. All three reward keyboard-only workflows. And all three assume the right answer to “what do you want next?” is to show you a list and let you pick.

That last assumption is where the conversation gets interesting.

Where AltTab, Contexts, and Witch differ from each other

The first axis is how the list looks. AltTab shows live thumbnails in a grid. Contexts shows a sidebar plus an overlay with type-to-search. Witch shows a compact text list with optional thumbnails. If the visual style of the picker is the thing you are optimizing for, the choice is mostly aesthetic — pick the one whose screenshots make you happiest.

The second axis is how you pay. AltTab is free and open source. Contexts is subscription or lifetime. Witch is one-time. None of those is morally better than another; they are reasonable trade-offs that match three reasonable business models.

The third axis is how granular the actions are. Witch ships the deepest action set (next/prev window, next/prev window of the active app, and so on). Contexts ships fewer actions but adds type-to-search and the sidebar. AltTab sits closest to the default Cmd+Tab and adds previews. Match the depth to how much you will actually use.

The fourth axis is what happens after the first day. AltTab feels great immediately because you already know Cmd+Tab and you are just getting thumbnails. Contexts and Witch feel great after a week because the configuration starts paying off. None of the three has a fixed-key map that lets you skip the list entirely.

Where Manico fits in alttab vs contexts vs witch macos

Manico exists because we wanted a fifth option that none of those three offers: a direct-key switcher that skips the list entirely. You assign one letter to each app you switch between most often — S to Safari, T to Terminal, V to VS Code, F to Figma, L to Slack — and from then on, switching is Ctrl+Tab (the default trigger, which you can rebind in Preferences) plus that single letter. No grid. No sidebar. No recency list. The keystroke is the decision.

The speed gain is not because Manico is fast. It is because the count of keystrokes per switch is bounded at one letter regardless of how many apps are open. AltTab, Contexts, and Witch all slow down a little as the window count grows, because the list gets longer and the scan takes longer. Manico does not, because there is no list to scan.

When an app has more than one window open — three Safari windows, two Terminal sessions, four Figma files — Manico shows a compact window selector for just that app’s windows. Pick the window with another keystroke. No Cmd+backtick roulette, no global exposé, no scrolling through a list of every window on the machine.

Manico is $15 as a one-time Paddle purchase, with a 14-day refund window and no subscription. It runs on macOS 13 Ventura or later, uses the Accessibility API like the other three, and stays out of your way until you press the trigger.

Try Manico — $15 one-time, 14-day refund

If a direct-key map sounds like the wrong default for your brain, one of the other three is genuinely the right answer. If it sounds like the right default — if you already know which app you want before the picker appears — keep reading.

How to choose

A practical heuristic, based on how a few hundred users have ended up describing their pick to us in support email:

Pick AltTab if you want zero dollars, a familiar Cmd+Tab feel, and live thumbnails. The total install-to-happy time is about three minutes.

Pick Contexts if the persistent sidebar idea actively excites you and you have the screen real estate to give it a column.

Pick Witch if you think in windows rather than apps, like the Many Tricks aesthetic, and want a deep set of window-level actions you can each bind to a separate hotkey.

Pick Manico if you already know which app you want before the picker appears and you would rather press one letter than scan a list. If you are not sure, try AltTab first — it is free, the install-to-test loop is fast, and the answer “the cycling itself is what I want to skip” will be obvious within a week.
