| Term | cPanel | InterWorx | Notes |
|---|---|---|---|
| Name for the entire product as a whole. | cPanel | InterWorx | InterWorx is a little less confusing than cPanel in this regard. |
| Name for the administrative suite (for server admins and resellers). | WHM | NodeWorx | |
| Name for the end-user suite (for domain owners). | cPanel | SiteWorx | |
| Term for non-server administrators who resell or control multiple end-user accounts. | Resellers | Resellers | |
| Additional domain that is managed by the end user and that has completely different content than other domains in the end-user's account. | Addon domain | Secondary domain | |
| Additional domain that is managed by the end user and that mirrors the content of another existing domain in the end-user's account. | Alias (previously known as parked domain) | Pointer domain | |
| Standard email account. | Email account | Email box | If you want to forward received mail to other accounts AND store a copy in a local mailbox, use the Send a Copy to function that is part of the email box feature in SiteWorx. If you just want to forward mail without storing a copy, use the Email Group feature. |
| Email address that only redirects mail to some other email address. | Email forwarder | Email alias | In InterWorx, email aliases only redirect to a single email address. If you want to forward to many addresses, use the email group feature. |
| Email address that directs mail to multiple different email addresses. | Email forwarder | Email group | cPanel handles forwarding mail to multiple accounts via the Forwarder interface, whereas InterWorx has a separate email group function. Email sent to an email group is not stored locally on the server unless the destination mail accounts happen to be on the same server. |
| End-user notifications when a specific event happens in or to the user's account. | Contact preferences | Subscriptions | |
| Control panel user accounts that the end-user can create themselves. | n/a | User account | cPanel does not currently allow you create multiple user accounts that all have access to the same cPanel account. InterWorx allows the end-user to create as many sub-user accounts as needed. |
| PHP script autoinstaller | Site Software | n/a (Softaculous Free) | cPanel has an optional installer for WordPress and WHMCS, but these are not always up-to-date. InterWorx doesn't offer any script installation features by default, but both control panels support popular installers like Softaculous or Fantastico. InterWorx includes a plugin to install the free version of Softaculous. |
