Matomo

Matomo is a self‑hosted web and app analytics platform written in PHP and using MySQL or MariaDB. After a brief installation, users add a generated JavaScript snippet to the pages they wish to monitor and can view real‑time reports on traffic, visitor behavior, and conversions. The software emphasizes full data ownership, allowing organizations to keep all analytics information on their own servers without external sampling or data‑sharing.

The tool targets website owners, marketers, and developers who need accurate metrics while complying with privacy regulations such as GDPR and CCPA. It offers features like a Google Analytics importer, personal‑data tracking controls, and a data‑warehouse connector, all built on an open‑source GPL‑3.0 codebase. Because it runs on standard PHP and MySQL stacks, it can be deployed on any operating system or hosting environment.

Matomo distinguishes itself by combining a free, subscription‑free model with a strong focus on ethical data handling. The project is maintained by a large community, includes extensive automated testing, and provides a security bounty program to address vulnerabilities promptly.
