Every window,
one Tab away.
A free, open-source window switcher for your Mac. Hold ⌥, tap Tab, and see every window — even the ones on other desktops.
Unlock it, then hold ⌥ and tap Tab. No keyboard? Use the button. Already running Ferry? It steps aside on this page.
Switching, the way it should have been.

Every Space
Other desktops, minimized and hidden — marked, not missing.
Dock previews
Rest on an icon to see that app’s windows.
Search

Quick actions
W closes, M minimizes, Q quits — without letting go.
Asleep until needed

Light enough to forget.
Measured on an M4 Pro with ten windows open. Ferry wakes up when you press the shortcut or rest on the Dock, and goes back to sleep.
Free. Quiet. Yours.
No account, no tracking, no trial.

Questions
Is it really free?
Yes. Ferry is open source under the MIT license. No trial, no Pro version, no upsell.
Why does it need Accessibility?
To list your windows, notice the shortcut and bring the window you pick forward. Without it a window switcher can’t switch windows.
Is it recording my screen?
No. Screen Recording is optional and only used to take one small still picture of a window when the switcher or a Dock preview is about to show it. Pictures stay in memory, are dropped when the window closes, and are never saved or sent anywhere. Skip the permission and Ferry shows app icons instead.
Can it replace ⌘Tab?
Yes. Pick ⌘ in Settings and Ferry takes over ⌘Tab while it runs, then hands it back to macOS when you quit.
Can I use it next to AltTab or DockDoor?
Better not at the same time: they listen for the same shortcut and the same Dock hover. Pick one.
macOS says it can’t be opened.
Builds aren’t notarized yet. Right-click Ferry and choose Open, or run xattr -dr com.apple.quarantine /Applications/Ferry.app.
Does the little ferry on the wallpaper do anything?
It moves along a bit every time you switch windows. That’s it. That’s the feature.
