We've been working on something that has yet to be added to this list, but I feel it's worth mentioning.
It's a self-hosted OS alternative to Google Analytics, much like Matomo (formerly Piwik) but less focused on developers and way more opinionated in terms of what data is visualized.
It's called Fathom Analytics[1]. Eventually we want to provide a paid hosted option much like what Ghost is offering to make sure we can keep on supporting it. For now, our development efforts are paid out of our own pockets.
