The Cloud Version doesn't require any technical knowledge.  You just sign up, select the apps and extensions your need, and Gahela handles all tech of running a web site.  You can have a web site running in less than an hour.  You never need to install anything, or worry about updating your software.  You simply pay a monthly fee based on the amount of visitors and Apps & Extensions you need.  You still have access to most of the source code, and can change anything related to your sites appearance and content through the powerful Gahela Website Editor.  No HTML, CSS or JavaScript knowledge is required (but all of this is available to edit for advanced users).

The Self-hosted version requires a moderate amount of technical knowledge to install and get running.  The self hosted version requires you to have a server (sometimes called a hosting package), and then install the Gahela software on your server.  There is a higher initial cost, but there are no monthly fees, and you have full access to the source code to modify the software to fit any unique business situation.  Your license never expires, and access to automatic-updates and 24/7 support is available through the Gahela service packages.
