Weebly is a web page design tool built to make it VERY easy to make your own web site.
Weebly is very competitive with Wix and SquareSpace. It is basically the same type service and is subscription based.
To use the Weebly Web Design App, you will need a hosting package.
The standalone version of Weebly can be used with ANY hosing company independent of Hostica. This means you should be able to change hosts and take your Weebly website with you.
To use Weebly with Hostica, you will need to add it as an ADD-ON service to an existing hosting package in your cPanel account.
