Plausible

Plausible is a lightweight, open-source, privacy-focused web analytics tool that works without cookies and gives a simple, single-page report.

Plausible deliberately moves opposite to the heavy tools: its script is tiny, it sets no cookies and so usually needs no consent banner, and the whole report fits on one page. That simplicity is both a strength and a limit: Plausible intentionally lacks deep product analytics (multi-step funnels, behavioral cohorts, session replay) and does not want them; if your question is “how many visits, from where, on which page” it answers, if it is “what do users do over several weeks” it is the wrong tool. Like Matomo, Plausible is open-source and self-hostable but is no country's domestic tool; its cloud version is hosted on European servers. Being cookieless also does not mean “zero privacy concern”, only that it uses a lighter tracking model.
