The ZPanel project consists of team members from all over the world as well as a growing amount of users from the community that have designed and developed both third-party modules and themes for ZPanel.
The project seems to be no longer maintained. Last version, 10.1.1, released on 3rd March 2014, can be still downloaded from the official website and the source code is available on Github. ZPanel's source code has been ported to Sentora
Known security holes unpatched.
Comments and Reviews
Said about ZPanel as an alternative
I have been using zPanel (old ver) / Sentora (new) for a few years. Excellent product to manage some 50 domains.
ZPanel is a open source hosting management solution, providing similar functionality like plesk or cpanel for managing webservers and hosting accounts.
