Shortlist

Why these names

• PostHog — human 84, agent 90. 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. Compare with Google Analytics 4
• Amplitude — human 79, agent 82. Amplitude is a product analytics cloud used by growth and data teams for funnels, retention, and taxonomy. The chart UI is the human product. Ingestion APIs and the dashboard API serve agents. Heavier than PostHog for teams that want a vendor, not a repo. Compare with Google Analytics 4
