And it's "Wordpress easy" to setup and doesn't require special access or server config?
Yes. On the first run it will take you to a wizard to set it up.
There's even a plugin for wordpress that embeds matomo itself if memory serves right.
It's as easy as setting up GA in WordPress. Just inject the JavaScript snippet built by your Matomo instance when creating a new tracker.
I think the question was if the software itself is actually simple to set up with a commodity web host. As easy as upload via ftp and configure in webbrowser easy.
Oops, my bad. You are totally right.
Totally! Just set an instance up the other day. Done in five minutes, you'll only need database credentials and a somewhat "normal" PHP setup.
