In the app you can adjust the colours, bars, flow speed and twist. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Bar Stream FAQ
How do I set Bar Stream as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Bar Stream 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 Bar Stream as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Bar Stream plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Bar Stream free?
Bar Stream 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 Bar Stream a video loop?
No. Bar Stream 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 Bar Stream 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 Bar Stream costs next to nothing in everyday use.
Which Macs does Bar Stream run on?
Bar Stream needs macOS Tahoe 26 or later.
