Free vs Pro
Everything in Free stays free.
Free is fully functional on its own. Pro is the connected service: it measures, scores and proves what the fixes achieve.

Free Install from WordPress.org Pro Purchased from your scan report
Pro is purchased from inside your scan report — there is no separate checkout on this page.
How to go Pro
Three steps, nothing lost.
Pro replaces the free version automatically — your settings are kept.
-
Scan your site and get a license
Run the free scan, see your report, and purchase Pro from there. Your license key arrives by e-mail and appears on your account page.
-
Install the Pro package
Download the Pro plugin from your account page and install it. It replaces the free version automatically — your settings are kept, nothing is lost.
-
Enter your key
Paste the license key under Settings → License. Licensed scans, the report link and automatic updates unlock in the same panel.
Built to be trusted
Three things the plugin will never do.
-
It never writes to your files
Every fix is served virtually and can be switched off without a trace.
-
It never modifies your content
Turn a module off and it is gone — nothing remains in your database or theme.
-
It never cloaks
Humans and bots see the same content — only the format may differ when a client asks for it.
