Framework7 vs JUniversal: What are the differences?

What is Framework7? Full Featured HTML Framework For Building iOS Apps. Framework7 - is a free and open source mobile HTML framework to develop hybrid mobile apps or web apps with iOS native look and feel. All you need to make it work is a simple HTML layout and attached framework's CSS and JS files! Framework7 doesn't force you to write some custom tags that will be converted by JavaScript to something else.

What is JUniversal? 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.

Framework7 and JUniversal can be primarily classified as "Cross-Platform Mobile Development" tools.

Some of the features offered by Framework7 are:

  • iOS Specific
  • UI Components
  • Swipe Actions

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

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

          Comment from HackerNews (https://news.ycombinator.com/item?id=8998736)

          This is how Google Inbox and Google Spreadsheets works. See the slides from my recently produced GWT Create Session (http://t.co/ZvoaHxCoZT). J2ObjC slide deck here (https://docs.google.com/presentation/d/1mW_Plm5jAygELf7qjVK7...) Videos of the conference will be online soon.

          Prior to that, some 20% Googlers also produced the PlayN library (https://github.com/threerings/playn) This was taken over by Michael Bayne who added an iOS backend by Bytecode -> IKVM -> Mono conversion. I beleive j2objc and RoboVM backends exist now as well.

          The major benefit of the j2objc approach is the avoidance of GC in favor of ARC, the conversion of message-sends into C-method calls when possible, and integration with existing iOS toolchain.

          When we started, it seemed like an iffy idea, but after developing a product delivered to millions of users on a high volume site (gmail) that has 70% code sharing, and being able to simultaneously develop, test, and deploy across the platforms reasonably efficiently, a lot of skeptics have become converts to the concept.

          Powerful, flexible, many beautiful widgets and a low learning curve.
