Free VPS control Panels
Some web site owners argue that the best control panel is one that you pay for. But others say that free control panels can do just as good a job. Here are a few free options that are available.
Kloxo is considered to be a very good alternative to Cpanel. It offers easy installation and a very similar interface to Cpanel. Although it does support many OS’s, Kloxo still does not support CentOS6.
ZPanel supports a wide range of operating systems including Windows. However, it may require more tech savvy to use. Less experienced users may find the lack of tutorials and support to be frustrating.
EHCP supports a higher number of operating systems than Kloxo does. EHCP offers an easy user interface and appearance and functionality similar to that of Cpanel.
