InterWorx is web hosting control panel software developed by InterWorx LLC. The application is divided into two interfaces: NodeWorx, which is used by a server administrators to manage a server, and SiteWorx, which is used by a website owner to manage a particular web site. The NodeWorx interface also contains functionality for web hosting resellers to securely manage multiple SiteWorx accounts without allowing the ability to manage server daemons and configurations.
Application-based support includes Apache, PHP, MySQL, Perl, and Djbdns (DNS). Email based support includes POP3, IMAP, SMTP services using Qmail. InterWorx is accessed via https on port 2443.
In addition to a web-based user interface, all InterWorx functions can be managed from the command line or API. InterWorx requires a dedicated server or virtual private server. System requirements of InterWorx are minimal, as it may run server clusters on Raspberry Pi devices using the ARM chipset.
