Duplicate Windows visually copies any window in macOS live and on-the-fly. It’s like display mirroring for individual windows!

• Duplicate any window

Select any window on your Mac, and get an instant resizable copy that stays up to date with the original.

• Monitor anything. Don't disrupt your workflow.

Watch videos. Watch a sports game. Monitor your servers. Keep an eye on any window you like. Just duplicate it, tell it to stay on top, resize it to just how you want it and get on with your work.

• Presenter Mode for any software.

You can duplicate windows across monitors. Drive a software demo with your notes right along side on your laptop screen, while only projecting the software you're demoing.

You can duplicate as many windows as you want, and have as many copies of a window as you want.

Good but I want more

I wanted a mac alternative for the windows software OnTopReplica. This does fit some of my needs, but I would enjoy things like cropping support and more advanced features.

Not bad for just duplicating full-size windows.

Good but not Great

1st - how do you contact the develper? The Website and Support links offer nothing.
2nd - how can you capture a window, close it, and keep the image in the duplicate?
