Licenses

Plesk, with latest version Obsidian 18.x, is available in the following license configurations: * Plesk Web Admin Edition: 10 domains. * Plesk Web Pro Edition: 30 domains. It also includes Plesk WordPress Toolkit full-featured. * Plesk Web Host Edition: Unlimited domains. The administrator can also create additional reseller accounts. The license price also distinguishes whether a license can be used for a dedicated server or a virtualized server. Licenses for dedicated servers are usually slightly more expensive.

Pricing

Plesk sells all three licenses for a monthly or annual price directly. All three editions can also be obtained from official license resellers. In March 2018, Plesk announced its first price adjustment in 18 years of business, increasing the prices of all Plesk licenses that had versions earlier than 12. The company claimed that it was to cover the increasing cost of support and management over the past two decades. Following the announcement, Plesk created a FAQ page.

Support

Live and email support for Plesk is available in English, Russian, Spanish, German, Portuguese, and Japanese. Plesk licenses purchased directly from Plesk include full free support.

Criticisms

One criticism of Plesk is that the recommended method of removing it is a complete reinstall of the OS after backing up, which complicates the concept of trialware by binding an administrator to the product by facing considerable downtime of a server.
