Material Kit vs sauron (framework): What are the differences?

Developers describe Material Kit as "Free Bootstrap UI Kit Based on Material Design *". Material Kit is a Free Bootstrap UI Kit with a fresh, new design inspired by Google's material design. You asked for it, so we built it. It's a great pleasure to introduce to you the material concepts in an easy to use and beautiful set of components. Along with the restyling of the Bootstrap elements, you will find three fully-coded example pages, to help you design your next project. On the other hand, *sauron (framework)** is detailed as "An HTML Web Framework for Building Web-Apps". With the goal to closely adhere to The Elm Architecture. As with elm, sauron doesn't use macros to provide the view, instead it just uses plain Rust function calls to construct the view.

Material Kit and sauron (framework) can be primarily classified as "Front-End Frameworks" tools.

Material Kit and sauron (framework) are both open source tools. It seems that Material Kit with 5.11K GitHub stars and 512 forks on GitHub has more adoption than sauron (framework) with 751 GitHub stars and 10 GitHub forks.
