Key learnings from peers
Last updated Mar 25, 2026

Valuable Features

  • "Uses standard Java, with low rewrite requirement for existing applications."
  • "To the best of my knowledge CN1 is better than some of the available mobile app development frameworks such as Xamarin and Nativescript because it gives almost 100% -- if not 100% -- write once run anywhere."
  • "A few things that stand out to me are a well-documented and pretty extensive API, build server, access to native functionality via native interface, easy extension with third-party libraries, active developer support, and attractive pricing."

Room for Improvement

  • "Core Java features are not fully supported (introspection, serialization) and many standard functionalities (windows, events) are implemented in an idiosyncratic way, not standard Java."
  • "Testing through a CLI simulator is free but difficult to setup."
  • "Windows Phone port. However, that is actively being improved and should be released later this year if all goes well."
These insights are based on the in-depth reviews provided by peers to help you make a better buying decision.

Codename One Reviews Summary
Author infoRatingReview Summary
Chicken Little at a tech vendor with 51-200 employees4.0I find its standard Java use and low rewrite valuable for cross-platform app porting. However, core Java features (introspection, serialization) are not fully supported, and standard functionalities are implemented idiosyncratically.
Senior Software Engineer at a tech services company with 501-1,000 employees4.0I find CodenameOne excellent for rapid, affordable development. With great support, easy setup, and a rich API, I've had no issues. Though the native look isn't 100% identical, I recommend it as a valuable cross-platform solution.
Software Engineer4.5I find the GUI builder most valuable. Based on my experience, CN1 offers superior "write once run anywhere" and cost efficiency compared to Xamarin and Nativescript, which are also good but have limitations.
