JUniversal vs Web Starter Kit: What are the differences?

Developers describe JUniversal as "A new, Java-based approach to cross-platform mobile apps (used by Google Inbox and Google Spreadsheets)". The vision of JUniversal came from some guys at Nokia who possess considerable expertise both in Java and in building cross-platform apps. They built this tool to provide an elegant way to translate source code and make it useful across multiple platforms. JUniversal offers you the freedom to write your shared code in Java and then translate it to C# (available now) or to C++/Objective C++ (coming soon). You can also combine JUniversal with Google’s j2objc translator to translate Java to Objective-C for iOS. On the other hand, Web Starter Kit is detailed as "Boilerplate & Tooling for Multi-Device Development". Web Starter Kit is a starting point for multi-screen web development. It encompasses opinionated recommendations on boilerplate and tooling for building an experience that works great across multiple devices. We help you stay productive and aligned with the best practices outlined in Google's Web Fundamentals.

JUniversal and Web Starter Kit can be categorized as "Cross-Platform Mobile Development" tools.

Some of the features offered by JUniversal are:

• OAuth (based on Scribe)
• JSON
• Unit testing (JUnit)

On the other hand, Web Starter Kit provides the following key features:

• Multi-device responsive boilerplate
• Living component style guide
• Cross-device Synchronization

JUniversal and Web Starter Kit are both open source tools. Web Starter Kit with 18.6K GitHub stars and 3.21K forks on GitHub appears to be more popular than JUniversal with 132 GitHub stars and 22 GitHub forks.
