Plesk (ex: Parallels Plesk Control Panel, Plesk Server Administrator, or just Plesk) software package is a commercial web hosting automation program. Originally released under the U.S. company Plesk Inc. and designed in Novosibirsk, Russia, Plesk was acquired by SWSoft in July 2003.[1] SWSoft renamed themselves under the Parallels name (a brand which had been acquired by SWSoft) in 2008.[2][3]


Plesk 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.

Plesk for Linux/Unix supports multiple POSIX platforms, including Debian, Fedora, FreeBSD, Red Hat Linux, SUSE and Ubuntu. Plesk for Windows supports Windows Server 2003, Windows Server 2008 and Windows Server 2012 operating systems.

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.


Plesk has several software packs that are not part of the main Plesk code base. These add-ons are designed to fully interact with Plesk , and they include:[4]

  • WordPress Toolkit
  • Developer Pack
  • Security Core Complete by Atomicorp
  • Control Suite for Windows
  • Kaspersky Antivirus
