Matomo (formerly Piwik) was created in 2007 by Matthieu Aubry as an open-source alternative to Google Analytics. The rename from Piwik to Matomo happened in 2018 — “matomo” means “honesty” in Japanese. It’s the most widely used open-source analytics platform, running on over 1.4 million websites in 190 countries.
The key selling point is data ownership. When you self-host Matomo, all analytics data stays on your servers. No third party has access to your visitor data, no external company can mine it for advertising, and you maintain complete control. This has made Matomo popular with governments, universities, healthcare organizations, and companies in regulated industries.
The feature set rivals Google Analytics: real-time visitor tracking, goals and funnels, ecommerce analytics, custom dimensions, event tracking, heatmaps, session recordings, A/B testing, and content engagement metrics. Many of these features require paid plugins, though the core analytics engine is free.
Matomo On-Premise is free and self-hosted. Matomo Cloud is a paid, managed hosting option for organizations that don’t want to maintain servers. The marketplace offers both free and premium plugins that extend functionality.
GDPR compliance was a turning point for Matomo. When the regulation took effect in 2018, organizations across Europe scrambled for Google Analytics alternatives that could guarantee data stayed within their infrastructure. Several EU government agencies and the European Commission itself switched to Matomo.
The platform has matured significantly over its 17-year history. It’s no longer just a “privacy alternative” — it’s a capable analytics platform that happens to respect user privacy. The heatmaps, session recordings, and A/B testing features bring it closer to tools like Hotjar and Optimizely.
For organizations where data sovereignty is a requirement rather than a preference, Matomo remains the most proven option.
