Virtualmin

Virtualmin is a web hosting control panel designed to manage multiple virtual servers on a single physical server. It is implemented as a module within Webmin, a web-based system administration interface, and provides a centralized platform for configuring and administering hosting environments. Virtualmin is available in a free Community Edition and a paid Pro edition, with the latter offering additional features for commercial hosting operations.

The software automates provisioning and management tasks across virtual servers, including domain management, mail domains, databases, DNS zones, and web applications. It supports web servers such as Apache and Nginx, and database backends including MySQL/MariaDB and PostgreSQL. Features include SSL/TLS automation (notably via Let's Encrypt), a script installer for popular applications, backups and restores, quotas and resource management, and monitoring and reporting tools. Virtualmin is designed for multi-tenant hosting, allowing separate virtual servers and user accounts, with role-based access controls and automation capabilities. It also exposes an API for automation and integration with other systems.

Virtualmin runs on a range of Linux distributions, commonly including Debian/Ubuntu and various Red Hat–family distributions, and is built to integrate with Webmin’s modular architecture. This makes it suitable for administrators seeking an open, extensible alternative to other control panels, with emphasis on multi-server hosting, cost efficiency, and a consolidated management interface for server, domain, and application administration.

History and licensing: Virtualmin has been under active development since the mid-2000s. The Community Edition is open source under the GPL, while Virtualmin Pro provides enhanced features and commercial support.
