at the moment we are not producing so much code as you might have realized on github.
privacyIDEA is still based on pylons, which is a rather old python framework and which is not actively developed anymore. Therefor, at the moment I am investigating new possibilities where to migrate privacyIDEA to come up with a new shiny 2.0.
This will be with the beginning of next year.
We are investigating things like flask, knockout.js, bootstrap, angularJS… to build a lightweight, modern system with an attractive UI.
If you have any comments, suggestions and ideas, please drop us a note.
