DirectAdmin

DirectAdmin is a web hosting control panel for Linux servers. The homepage describes it as a web hosting control panel with a web interface for administrators, resellers and users. The install guide sets it up with a setup script run as root on a clean server, through either a web-based installer or the command line. Once installed, the panel runs as a service on the server: its task queue restarts a service that has crashed, and the control panel answers on a port of that server.

Worth knowing

DirectAdmin is proprietary and sold by license, and a client account is required to buy one. The retail license tiers differ in how many accounts and domains they allow, and the Pro Pack feature set was retired so that every license carries the same features. The product runs on the server itself, so it needs a host where the operator can install software as root, and the install guide asks for a server that runs one of the supported Linux distributions.
