In the app you can choose the colours, how often a new tab opens and how many tabs can pile up. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Tab Overflow FAQ
How do I set Tab Overflow as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Tab Overflow in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.
Can I use Tab Overflow as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Tab Overflow plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Tab Overflow free?
Tab Overflow is included in SCRNSVRS Unlimited. It's free for your first 7 days; after that Unlimited is $1.99/month or $9.99/year (€1.99/month or €9.99/year) for every screensaver, including new ones. It can also come up in Free this month, when 25 premium screensavers are free for everyone.
Is Tab Overflow a video loop?
No. Tab Overflow is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.
Will Tab Overflow slow down my Mac or drain the battery?
No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Tab Overflow costs next to nothing in everyday use.
Which Macs does Tab Overflow run on?
Tab Overflow needs macOS Tahoe 26 or later.
