What is Dragonfly CMS?
Dragonfly CMS is a powerful, feature-rich, Open Source content management system which was based on PHP-Nuke 6.5 in the "CPG-Nuke CMS" days. We have spent over a year developing Dragonfly CMS, paying close attention to security and reliability. The release of Dragonfly marks yet another exciting milestone in our history.

What programming language does Dragonfly use?
Our software is written in PHP—the fastest programming language spreading the net today, combined with your choice of either MySQL or PostgreSQL (experimental).

What does my server require?
The prefered setup is to have:
- PHP 4.3 or higher.
- MySQL 4.0.x
MySQL 5.x is not supported in versions up to 9.0.6.1
(MySQL 4.1+ and PostgreSQL 7.6+ are supported in CVS)
- Apache 1.3 or higher (other httpd clients are also supported like IIS5/6, Raiden, etc.)
- GD 2, ImageMagick, netPBM or any other image manipulation software

Why Switch to DragonFly:

Why Dragonfly CMS?
Unlike other content management systems on the net, we maintain a high level of security, so that you spend time managing your site, not patching it. Managing your site is easy with our powerful line of tools which include a debugging system, BBCode support in many areas, a built-in photo gallery, and a derivative of phpBB 2.0.x.
