Jasonette is licensed under MIT license. Take the code, build and publish your own apps, and do whatever you want with it!
There is no magical backend server you need to learn to use, pay for, or install to use Jasonette. ALL YOU NEED IS JSON. If you have a web server, you ALREADY have a Jasonette server.
Jasonette is essentially just an engine that maps JSON expression to native components and actions. It doesn't force you to drop everything and adopt the technology exclusively. You can extend it or even integrate it with your existing native code seamlessly.
