Matomo

Matomo (formerly Piwik) is an open-source web analytics platform that provides detailed website traffic analysis while keeping data under the site owner's control. It is the leading self-hosted alternative to Google Analytics, used by over 1 million websites including many government agencies and organizations with strict privacy requirements.

The platform tracks visitors, page views, referrers, search keywords, user flows, conversions, e-commerce transactions, and custom events. Dashboards are customizable with widgets covering real-time visitors, visitor maps, device types, and content engagement. The reporting interface is comprehensive and comparable in depth to Google Analytics.

Matomo's primary selling point is data ownership and privacy compliance. Since it runs on your own server, visitor data never leaves your infrastructure. This makes GDPR compliance straightforward because you are the data controller with full control over data retention, anonymization, and deletion. The platform includes built-in GDPR tools: consent management, data anonymization, opt-out mechanisms, and data export/deletion for individual visitors.

For hosting providers, Matomo represents both a product opportunity and an infrastructure tool. Providers can offer managed Matomo hosting to privacy-conscious customers as an alternative to Google Analytics. The platform runs on standard PHP + MySQL infrastructure, making it compatible with most hosting environments.

Matomo also works without JavaScript tracking through server-side log analytics (similar to AWStats but with a modern interface). This hybrid approach captures both JavaScript-enabled browsers and server-side requests, providing the most complete traffic picture.

The Tag Manager (included free) provides Google Tag Manager equivalent functionality for managing tracking codes, conversion pixels, and other marketing tags. Heatmaps, session recordings, and A/B testing are available through premium plugins.
