You can self-host Fathom, I do.
It's very basic compared to Piwik, but it runs on PostgreSQL, my DB of choice, and it's written in Go, not PHP, which means it has higher performance and is more secure.

Just wanted to add that you can also use Fathom with MySQL or SQLite if that's more your cup of tea. It supports those 3 database engines right now.
