For those who haven't been following it's development, it's been renamed Matomo[1]. Definitely an option worth considering for deeper analytics while still being a bit more performant and respectful of privacy!

Thanks for sharing this summary. I had matomo in my notes, and was just wondering how it compares to Fathom.

If there are any more detailed comparisons, I'm all ears.

Good to know!

I tried it once on my potato server (which handled the HN front page just fine with php5.4 at the time (not as fast as php7) and 3 mysql queries per pageload) and it's super slow. If you run Wordpress, it might not make a difference. But if you run something low-powered, Piwik will kill your server.

Edit, sort of: I should note that this was years ago, maybe four years or so. I still use the same server so it probably only got slower, but on the off chance that it actually got faster... you might give it a go.
