Are there platforms to build your own website analytics service?

Question

Programming

Good day to all!
Tell me if there are any ready-made solutions (platforms) for compiling your own analytics (metrics) for visiting your site? For example, getting user demographics, number of sessions, goal conversion signs, etc., just solutions for creating your own metrics, and not using ready-made google and yandex metrics?

Answer 1

Full.
On normal shared hosting, when I used them 10 years ago, they turned on the log analyzer by default, and even then there were options for which analyzer to turn on.
Now there are more powerful systems.
But, due to competition with the two you mentioned, embedded analytics systems are divided into primitive or expensive ones.
With good functionality and free - no, due to the presence of Google Analytics and Yandex Metrics.
