Hello
We are developing the new Ketcher and we are trying to make it better. The internal architecture was fully reorganized. As it is in active development stage, the deploying the source code (to EPAM GitHub) is on hold for now (actually, it is more bureaucracy issue). But we have released source code for one of the latest "stable" release (it was tested well). One can find it here
http://lifescience.opensource.epam.com/download/ketcher.html#ketcher-2-0-0-alpha-3We will try to finish the general re-factoring and "publicize" the source code under GitHub. Unfortunately, it is hard to tell time line. Definitely, it should be this year. Please keep in touch
With best regards
Alexander
