Last week, we introduced the privacy
concerns with using Google Analytics (GA) and presented two lightweight
open-source options: GoatCounter and Plausible. Those tools are useful
for site owners who need relatively basic metrics. In this second article,
we present several heavier-weight GA replacements for those who need more
detailed analytics. We also look at some tools that produce analytics data
based on web-server-access logs, GoAccess, in particular.
