Offline GUI Javascript Coding?

Over the years, I’ve learned enough different programming languages to last a lifetime. I’ve probably forgotten more than I ever learned. To that end, I kind of like the Kano GUI coding program. What I don’t like is “cloud based” software. I am planning on programming the Kano Computer Touch as an internet radio. Is there any offline version of the Kano Coding software or anything similar that is publicly available?
