The Quantum hosting plan is a revolutionary new addition to our Managed WordPress hosting lineup, available exclusively to our Agency members.

Select Quantum plan when creating a new site

While Quantum is not suitable for e-commerce sites, it is ideal for small blogs, static sites or when developing new client sites. Sites can be upgraded to any other plan at any time.

Quantum offers the same fully dedicated resources as our other hosting plans, at the lowest price possible.

To achieve this, we’ve had to pare down some of the features available on this plan to avoid maxing out server resources and ensure your site has the power it needs for optimal performance.

This document aims to inform you of those restrictions so you don’t hit any unexpected snags.

Please see our Plans & Usage Limits doc for more information on server specifications for this plan.

All themes from wordpress.org are allowed on the Quantum plan, and you can upload themes via Themes > Add New > Upload in the site’s wp-admin.

Note that if a theme comes with its own integrated page builder, like Divi for example, that will work just fine.

However, if the theme comes packaged with a page builder as a separate addon plugin, you would not be able to activate that plugin unless it’s in the list of allowed plugins below.

As Quantum sites have rather limited resources, plugins can only be installed from wordpress.org via Plugins > Add New in the site’s wp-admin. You cannot upload plugins to Quantum sites.

Plugins that can be installed are limited to those we have determined to have little to no negative impact on performance. Plugins that cannot be installed on Quantum sites will have a Not Available label in place of the Install Now button in your site’s wp-admin.

Plugins restricted on Quantum sites

Of course, all WPMU DEV free and Pro plugins can be installed on Quantum sites except Snapshot Pro and Shipper Pro plugins.

Here is the full categorized list of plugins allowed on Quantum sites. This list will be updated periodically with additional plugins upon review of their performance impact.
