Why KinsMirror
Keep an eye on a window you don't want to switch to — a build log, a chat, a video, a second terminal — by pinning a live mirror of it on top of whatever you're doing. Powered by Apple's ScreenCaptureKit for smooth, GPU-composited frames.
Mirror any window
Pick any on-screen window — another app or another terminal — from the picker or the Dock menu. Its live contents stream into a floating panel.
Always on top
The mirror floats above everything, across Spaces and full-screen apps, so you never lose sight of it.
Drag, snap & scale
Drag it anywhere with edge snapping, resize with the grip (aspect preserved), or scale to 25/50/75/100% of the source in one click.
Roll up to a title bar
Double-click to collapse a mirror to just its title bar when you need the space — double-click again to bring the picture back.
Mirror several at once
Open as many mirrors as you like; each is independent, and a focus menu jumps you to any of them.
Jump to the source
One click brings the real window to the front when you're ready to act on what you've been watching.
