For me the quarantine turned my side-project into a full-time project. So I am now working non-stop on https://www.usertrack.net, trying to make the best analytics tool and also start a broader self-hosted movement.
Very interesting! I've been looking for a self-hosted analytics tool to replace the Google. I'm going to take a closer look.
Btw, I don't think you need to start a broader self-hosted movement; it's been building for a while. See https://github.com/awesome-selfhosted/awesome-selfhosted for example. Keep up the good work! You're not alone.
