Matomo, formerly Piwik, is a web analytics platform positioned as a privacy-focused alternative to Google Analytics. It reports on pages, traffic sources, conversions, events, funnels and segments, and adds A/B testing, heatmaps and session recordings. Privacy options include cookieless tracking, data anonymisation, access controls and raw-data export. Matomo can be used as Matomo Cloud, hosted by the vendor, or as a free on-premise installation on your own PHP and MySQL or MariaDB server.
The software is open source under the GPL v3 or later. The company behind it, InnoCraft Ltd, is registered in Wellington, New Zealand, and works remotely; transfers from the EU to New Zealand rely on the European Commission's adequacy decision. According to its data processing addendum, Matomo Cloud is hosted on Amazon Web Services in Frankfurt, with backups in Dublin. Self-hosting lets a European organisation keep all analytics data on its own infrastructure. Matomo reports ISO 27001:2022 certification.
