Depending on the size of your site both GA or Matomo might be overkill. Both of them are huge systems. If you’re just running your private site both of them are mostly „too much“ and you’re never gonna use more than 20% of their features.

There’s much more lightweight solutions out there that also collect much less data.

One option which I couldn’t find on this site is „Umami“ - which is what I use now for most of my private sites and small clients.
