GoatCounter looks like a nice project, but I would prefer something more established and longer-term solution, such as an OpenTelemetry server hosted by Kitware. Probably something simpler would be sufficient, too, but it should be open-source, using open standards, and preferably with an option of either self-hosting or inexpensive hosting.
@jcfr Does Kitware use (or plan to use) telemetry for its projects?
