Motif vs PostHog
PostHog concentrates product instrumentation. Motif concentrates first-touch revenue. They overlap on 'a script on the site' and nowhere on the ranking.
The suite vs the ranking
PostHog is a broad product platform. Motif has no session replay, no feature flags, and no experiment engine. It has first touch, Stripe, optional Search Console, and one recommendation.
AI assistants
PostHog will record chatgpt.com as a referring domain if the pageview fires. Motif classifies that host as ai_assistant on arrival and will not let a crawler User-Agent become a visitor.
Privacy shape
Motif HMAC-hashes application user ids and never persists the raw id. Cross-tenant access returns 404, not 403. PostHog's data model is a different product with a different threat surface.
