VestaCP is a light & fast web host management control panel, with simple and clear interface. Instead of adding more elements to work with, they prefer to remove as much as possible. The main goal was to improve the ergonomics of the control panel by reducing unnecessary movements and operations. It is all about using less, because less is more.
