I'm about to ditch Facebook tracking pixels and Google Analytics on my Saas, anyone have experiences with alternatives to Google analytics?

I use for quick simple sites. For something like a saas I find mixpanel is more useful as you can see what people are doing, not just tracking pageviews. Piwik may be worth a look too but I haven't installed it in about 8 yrs?

Piwik looks like a pretty good option! Thanks. is free and pretty powerful tool.
