Famous Framework vs Zepto: What are the differences?

Famous Framework: Build expressive user interfaces with consistent code and reusable components. The Famous Framework is a new JavaScript framework for creating reusable, composable, and interchangeable UI widgets and applications. It balances declarative with imperative and functional with stateful, and it's built on top of the Famous Engine; Zepto: Minimalist JavaScript library for modern browsers, with a jQuery-compatible API. While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. The goal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatile API, so you can concentrate on getting stuff done.

Famous Framework and Zepto can be primarily classified as "Javascript UI Libraries" tools.

Some of the features offered by Famous Framework are:

• Reusability / interchangability. The Famous Framework is built around powerful constraints and a declarative syntax that make it possible for components to be reused and interchanged.
• Application consistency. In an ecosystem where widgets/applications/utilities all follow the same guidelines, developers and designers both reap the benefits: less trial and error when attempting to integrate with others' projects.
• Integration with existing web standards. Although our integration is far from complete, from the beginning we've aimed to design and build the framework around existing web standards.

On the other hand, Zepto provides the following key features:

• zepto - Core module
• contains most methods
• event - Event handling via on() & off()

Famous Framework and Zepto are both open source tools. It seems that Zepto with 14.5K GitHub stars and 4.06K forks on GitHub has more adoption than Famous Framework with 401 GitHub stars and 69 GitHub forks.
