Does Custom Reports work as a standalone product?
On-Premise
No, the Custom Reports plugin is built on top of Matomo. To use it, you first need to install Matomo.
Matomo requires PHP, a MySQL database and a webserver like Apache or Nginx. Learn more about Matomo requirements. Alternatively, to take away the hassle of installing and maintaining your own Matomo, signup to the Matomo Cloud service.
