Djangoticia is an evolution of puppet-master using the Django framework. Design is Easily customizable for your brand or your specific needs.
So all embededd features of Django come with it. For example :
_ User administration (differrent rights for different users).
_ Security features (if you want to put your robot with a public internet access).
_ Integrated database.
And some few changes for my personnal needs :
_ Wi-fi administration (works only for RPI)
_ Individual server administratin (start and stop only the servers you need) :
_ Integration of monitor, snap and Jupyter in the framework.
Obviously it is totally free and open source : https://github.com/Roboticia/Djangoticia
