Kyfoo is a CMS licenced by the GNU GPL v3.
The system is generic and usable at the same time.
Generic: We built our own script syntax called kycode.
Usability: The website admin panel is very easy to use.
Kyfoo is written in PHP and uses MySQL+NoSQL for storage.
Download the latest version: kyfoo v0.4 [6/22/2014]
You are free to use that CMS. But keep in mind:
We are not even at v1 yet, so use it at your own risk.
Unlike a lot of Free Software content management systems,
the development of kyfoo is driven by it's commercial customers.
