What are the analogues of CMS PageKit?

Question

CMS

I stumbled upon a super lightweight tsms PageKit. I liked it, but unfortunately it is imprisoned for the UIKit framework. You don't really want to learn something new. Bootstrap 3 is closer to me.
Are there any similar engines that are either tailored for bootstrap, or universal without any problems like pagekit?

Answer 1

UIKit 2 is much more functional than Bootstrap 3. There is nothing complicated there, about the same.
