nuBuilder is Open Source. ..
This means any nuBuilder application you create can be moved from the server it originally started on,
to another server, any time you want.
Because you can download and install nuBuilder from github and restore your data from a backup.
Developing applications on platforms that cannot be moved is like furnishing your house,
but not being able to take any of it with you if you leave.
With nuBuilder you own the software you create, you don't just rent it.
