Apart from Plausible, Umami and Matomo, what other Open Source Alternative are there?

The first two doesn't really compete with GA, and does not offer some features many requires from GA ( such as returning visitors ). The last one has its own issues.

I'm biased as my team built it, but github.com/posthog/posthog is probably worth a look. We can provide basic GA functionality and a lot of more product analytics focussed functionality + feature flags.

I thought about GoatCounter too

I just check it out again and I instantly remember why.

It is ugly. ( Sorry )
