Originally designed in Novosibirsk, Russia, the hosting automation software was released by Plesk Inc. and went live first in 2001.[3] In 2003, Plesk was sold to SWSoft,[4] which became Parallels in 2008.[5][6][7] In December 2015 Plesk became a separate business entity,[8] which has since been acquired by Oakley Capital.[9]


Plesk's control panel allows a server administrator to set up new websites, reseller accounts, e-mail accounts, and DNS entries through a web-based interface. The administrator can create client and site templates, which predetermine resource-allocation parameters for the domains and/or clients.

As of October 2018, Plesk has integrated support for various Content Management Systems including WordPress, Joomla, Drupal and other web software such as git, Docker, Multi-server management, as well as framework ready environment for Node.js, PHP, Python, Ruby on rails and more. The previous version of Plesk (12.5) for Linux/Unix supports multiple POSIX platforms, including Debian, Ubuntu, CentOS, Red Hat Linux and CloudLinux.[10] Previous versions also supported openSUSE, Fedora and FreeBSD. Plesk for Windows supports Windows Server 2008, Windows Server 2012 and Windows Server 2016 operating systems.[11][12]

Plesk installs custom versions of or manages versions of MySQL and PostgreSQL databases (Microsoft SQL Server and Microsoft SQL Server Desktop Engine under Windows), Apache Tomcat Java platform server, and ColdFusion server.

The Plesk Platform includes extensions for Authentication, Backup, Developers, Domain and DNS.
