Hi
@nmdpa3, thank you for raising this question. I can well relate to this concern, it was one of my first thoughts, too, when Sitejet announced the free integration with Plesk. So I forwarded your question to the Sitejet team. Hendrik already responded to your request directly. For others who are also considering Sitejet as their website builder I'd like to provide the answer in short here:
Plans are that SiteJet will remain free with Plesk. It is set to become our standard website builder, integrating seamlessly with Plesk. We are committed to making significant investments into Sitejet. This means continuous updates and feature additions to ensure Sitejet remains at the forefront of website building technology. Sitejet is already included in Plesk licenses at no additional cost.
However, in the future, we might introduce some optional paid services on top of the free version to cater to specific use cases and offer even more comprehensive solutions. These enhancements will be carefully designed to provide exceptional value to those who opt for them. But even without such options, Sitejet already is a great website builder and adds a lot of value to your daily work with Plesk.
