Google Analytics 4

GA4 is the default marketing analytics for the open web after Universal Analytics sunset. The human UI is a well-known source of confusion. Measurement Protocol and the Data API let agents send and query events. We score the current GA4 product, not UA nostalgia, and we do.
PostHog

Agent90
PostHog is product analytics with session replay, feature flags, experiments, and surveys — open-core and self-hostable. Humans live in funnels and replays. Capture APIs, flags, and HogQL give agents a full product-data loop. We like that the company publishes pricing math.
