I have turned Yeti into a web application, it now works with most modern browsers on most OS's, even the iPhone and iPad. The backend was ported from C#/Rhino to Python/PythonOCC and the pages are served from Django with three.js assisting the webGl rendering.
On a local server it seems almost as fast as when it was on Rhino - although the OpenCascade API is nowhere as clean as the Rhino API. Entering text on the iPad is totally impractical but perhaps sliders in a future version might be better.
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
