AnalyticsWhat is Matomo?
Matomo (formerly Piwik) is an open-source, privacy-first web analytics platform. It can be self-hosted or run on Matomo Cloud, and is often chosen specifically so that analytics data stays under the site owner’s control rather than Google’s.
Why Matomo matters
Teams pick Matomo when data ownership, GDPR posture, or the ability to run analytics without consent banners (in cookieless configurations) matters to them. It is a deliberate, values-driven choice — finding it usually means the site owner has thought hard about privacy.
