Still deciding?
Common questions
Everything you need to know before choosing between Free and Pro.
Do I need Free before Pro?
No. SitePulse Pro is a single plugin. Installing Pro replaces Free on the site. There is no separate add-on step, and your existing Free configuration carries over.
Where does the Command Center live?
The SitePulse Center command console lives at sitepulse.me/my-account. Pro licenses sign in there; each connected site syncs metrics back through the Center.
Does Free send my data anywhere?
Free keeps local monitoring data in WordPress. It sends diagnostic data only after you enable PageSpeed and AI Reports. Pro cloud processing is enabled by default, disclosed before first upload, and can be disabled.
What does the trial include?
The Founders trial includes 14 days of full plugin and Command Center access with no card and no automatic conversion. Starter, Freelancer, and Agency trials require a card and bill after 14 days unless canceled; a reminder email is sent before billing.
