Matomo

A web analytics platform that tracks page views, visits and on-site behavior through a self-hosted tracker, with heatmaps, session recording and form analytics available as paid plugins on top. It offers a dashboard and reporting layer with scheduled email reports, a full API, and dozens of plugins for extending what it collects.

Marketing and product teams use it to see which campaigns and pages actually drive signups, and analysts rely on it for reporting that does not depend on third-party cookies.

Running it on your own server means visit data and the IP addresses behind it never travel to a remote vendor, and the database is a plain backup job.
