See every window. Switch in one move.
macOS's built-in Cmd+Tab cycles through apps.
NanoSwitch shows a thumbnail grid of every window — so you jump directly to the exact one you need.
Hold Cmd+Tab → thumbnail grid appears → navigate with Tab or arrow keys → release Cmd to switch.
No new shortcuts to learn. No configuration needed. Just a better Cmd+Tab.
- Window-level switching — see all open windows, not just apps
- Live thumbnail previews — see the content before you switch
- Current Space only — no clutter from other desktops
- Instant display — icons appear immediately, thumbnails load in background
- Lightweight — lives in your menu bar, runs silently in the background
- macOS 14.6 or later
- Accessibility permission — required to intercept Cmd+Tab
- Screen Recording permission — required for thumbnail previews
Both permissions are requested on first launch.
The app works without Screen Recording (falls back to app icons), but thumbnails won't be shown.
