Matomo (previously Piwik)[1] is a website statistics and analytics tool, similar to Google Analytics, but open source, and deployable to your own server. OpenStreetMap uses this on the main web front end, to gather stats on traffic and user flow. Some folks are able to login to our Matomo server at to view the resulting stats displays.

Restricted access

Access to view the stats displays of OpenStreetMap's Matomo is restricted mostly just to some of the System Administrators. This is mainly due to data protection issues. In accordance with UK data protection law and our privacy policy we can not reveal certain details of traffic data publicly. We can ask the admins for certain types of information and reports which they might look up for us, but we do not all get to see Matomo data directly. At least not at the moment. Somebody could investigate ways of opening up some anonymised displays.

This mailing list thread has some more info:

The Privacy Policy names the fact that the data might be published at and other locations in an anonymous fashion for research and other means.[2] As of February 2019, this data is not available there.


Matomo is deployed since at least December 2011. It was claimed that the program operated on the main webpage and the wiki.[3] However, this information was never confirmed. In 2013, Matomo was present on the main web front end only.[4] It could work with this wiki, but it is not used here.[5] The current configuration makes use of many plugins.[6]

German "Wochennotiz"(de) also uses Matomo.[7][8]
