Matomo (formerly called Piwik) is an open-source web analytics platform, a tool that tracks visitor activity on your website and presents it in charts and reports, much like Google Analytics does. The key difference is that you install Matomo on your own server, which means all visitor data stays in your own database and never goes to a third-party company. The setup process is designed to be quick: download and upload the software to your web host, run a brief browser-based installer, and then copy a small snippet of JavaScript code onto each page you want to track. After that, Matomo collects data in real time and displays it in a customizable dashboard where you can drag and rearrange widgets to suit your needs. Beyond basic page view counts, Matomo supports more advanced features such as tracking e-commerce transactions (when someone completes a purchase), setting goals (measuring conversions like newsletter sign-ups), campaign tracking, custom visitor segments (filtering your audience by specific criteria), geolocation (where in the world visitors come from), and email reports delivered on a schedule. The platform is built with a plugin architecture, so you can add or remove features as needed, and the analytics data is accessible via a programming interface (API) if you want to pull it into other systems. Matomo is written in PHP and requires MySQL or MariaDB as its database. A cloud-hosted version is also available if you prefer not to manage your own server. The software is released under the GPL v3 open-source license.
