Overlay2 is described as 'is like digital tracing paper for your computer. It opens a semi-transparent floating image over video capture or editing software, or 3D modelling software, so you can use the image as a reference or positioning guide' and is an app in the Development category. There are nine alternatives to Overlay2 for a variety of platforms, including Mac, Windows, Linux, the Web and Microsoft Edge. The best alternative is Afloat, which is both free and Open Source. Other great apps like Overlay2 are PixelPerfect (Free), Image Overlay Utility (Paid), LayerX (Free, Open Source) and Duplicate Windows (Paid).
