Matomo is an open-source web analytics platform that prioritizes privacy and data ownership, offering real-time insights, advanced tracking, and customizable reports — all without depending on third-party providers. Formerly known as Piwik, Matomo is used by over one million websites in 190 countries, including the European Commission, NASA, and multiple EU government portals. Matomo gives organizations 100% ownership of their data, provides unsampled reporting, and can be self-hosted for full data sovereignty — making it particularly valuable for organizations operating under GDPR, HIPAA, CCPA, or other strict privacy regulations.

For teams running dotCMS, Matomo provides a privacy-compliant way to understand how visitors engage with content — tracking page views, conversions, campaigns, heatmaps, and session recordings without sharing data with advertising platforms or third parties.
