Every monitor, always in view
Only for Mac

Mac
Know what's on every screen. Periphery shows your external displays live, in a floating panel on the screen in front of you.
Periphery shows a live preview of every external display in one floating panel, right on the screen in front of you. Plug in a monitor, a projector or a conference-room TV and it appears on its own, so you always know what the room is seeing.
If you present, teach, run demos, or keep half an eye on a dashboard across the room, this one is for you. No more turning around mid-sentence to check the projector. No more walking over to the other monitor to see whether the render finished. The screen behind you is now the screen in front of you.
BUILT FOR PRESENTERS
• Live previews of every connected display, updating as they change
• Glance at your slides, speaker notes and demo screens from where you sit
• The panel appears the moment a display connects
• Send one display to full screen and step through the rest with the arrow keys
FAST AND FLEXIBLE
• A global keyboard shortcut shows and hides the panel (⇧⌘P by default, and remappable)
• Lay the previews out side by side or stacked, with a corner radius you can adjust
• Frame rate from 0.5 to 30 FPS, smooth when you want it, easy on the battery when you don't
• Hides hardware-mirrored displays when you'd rather not see duplicates
MADE FOR YOUR MAC
• A native macOS app built with the Liquid Glass design
• Lives in the menu bar, with an optional Dock icon
• Launch at login so the preview is ready the moment you plug in
• Capture pauses the instant the panel is hidden, so nothing keeps running unseen
PRIVATE BY DESIGN
What's on your displays is often the most sensitive thing on your Mac, so none of it leaves the machine.
• No account, no analytics, no network access
• Previews are rendered locally and never leave your Mac
• Built on Apple's ScreenCaptureKit, fully sandboxed, and the screen is only read after you grant Screen Recording permission
Periphery needs macOS 26 or later and at least one external display.
