Lius is a statistics website counting the number of GNU/Linux users in the world. This project was created for fun, as an alternative to the deceased Linux Counter project. The name Lius comes from the words Linux and usage. Statistics are tied to the user's public IP address. If you have the resources, and are interested in running your own counter, you can download the source code from here.
Counters: GNU/Linux, Linux Mint, Ubuntu.
