MacTab icon

macOS & Windows · Window switcher

Switch windows,
not just apps.

MacTab replaces the built-in ⌘Tab / Alt+Tab switcher with a real window switcher — every open window in most-recent order, with a live preview of the one you're about to jump to.

Free · macOS 14+ · Windows 10/11 · Windows portable .exe (no install)

Why I built this — the making-of →

Built to get out of your way.

The one interaction that matters — hold the modifier, tap to cycle, release to switch — with everything you need to land on the right window fast.

Live preview

See the actual window next to the list, not just an app icon — so you land on the right one the first time.

Most-recent order

Windows are ordered by when you last used them, so the one you want is almost always second in the list — one tap away.

Keyboard or mouse

Hold-and-tap to cycle and release to confirm, or hover the list and click. Hovering previews; leaving the list snaps back to your selection.

Every window

Switches between individual windows, not just apps — including multiple windows of the same program.

One design, native on each.

Not a cross-platform wrapper — each version is a native app that shares the same behavior and switching model.

macOS

Swift · AppKit

A menu-bar app that takes over ⌘Tab / ⌘` with four hotkey slots, an optional 3-finger trackpad gesture, and live window thumbnails.

Windows

C# · .NET · WPF

A tray app that replaces Alt+Tab, with live DWM window previews composited right into the switcher and mouse hover + click support.
