I've recently whipped up my own self-hosted analytics solution [0] based on SQLite, Bash and Metabase. It's all self hosted, easy to install and very flexible with regards to the queries you can write and display. Metabase comes with a lot of cool features for display, live reload and other cool stuff. :)
