jsblocks vs Zepto: What are the differences?

Developers describe jsblocks as "An Isomorphic JavaScript Framework Faster Than React". From simple user interfaces to complex single-page applications using faster, server-side rendered and easy to learn framework. On the other hand, Zepto is detailed as "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.

jsblocks and Zepto can be categorized as "Javascript UI Libraries" tools.

Some of the features offered by jsblocks are:

• Server-side rendering
• Debugging experience
• Faster

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

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

jsblocks 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 jsblocks with 2.82K GitHub stars and 120 GitHub forks.
