Can you specify what you mean by "customer facing analytics", and what use case you have in mind? Metabase is a dashboard tool that's mainly used by internal data teams.

Charts, counters, tables, or dashboards that surface analytics for stakeholders or clients, rather than only the company’s internal team. Yes the embedded analytics part is what I was thinking when I cited metabase as an example
