Cloudflare has two different analytics products which makes things pretty confusing. "Web analytics" is always free and under Analytics > Web Analytics at the account level. That's the one you want, not "traffic analytics" under Analytics > Traffic in the individual website.

But yeah it is very basic.. Visits, pageviews, referrer, browser, RUM metrics and a few other things. Tools like Plausible give you some more features but still a lot less than GA3. Tools like Piwik Pro give you something equivalent to GA3. Product analytics tools like Posthog give you something more like GA4.
