Develop Plesk Extensions

Build apps and solutions and integrate them with Plesk to simplify the lives of Web Professionals. Quickly turn your product or in-house solution into a Plesk extension with the help of Plesk specialists and our technology partners, then jointly promote and sell your extension to the world of Plesk.

Have a Plesk Extension that you want to share with the world? You can now submit it to be added in the Plesk Extension catalog, by following the steps outlined below:

1. Package your extension using the latest version of Plesk SDK (11.5+) according to submission checklist below.
2. E-mail the Plesk Extension team at [email protected]. Provide a link to your packaged extension, and request addition to the catalog. If you have any additional information regarding your extension, make sure to provide it.
3. After we have checked the extension, one of the following things will happen:
a. Your extension will be published in the catalog.
b. We will ask you to fix issues we’ve found and resubmit your extension. Submission of extension updates should follow the same steps.
