Author here. Yeah, Sikuli was one of the role models for Kantu. The way I see it is that Kantu combines the usability of iMacros (which I created years ago) with the no-compromise computer-vision approach of Sikuli. The key difference between Sikuli and Kantu is that the later works inside the web browser. So unlike Sikuli, you can run many instances of Kantu at once and in the background. Kantu does not take over your desktop.... and you don't have to learn Python ;)
