PostHog Cost Tuning
Overview
PostHog Cloud pricing is event-based: 1M events/month free, then usage-based pricing beyond that. Session recordings, feature flag evaluations, and surveys each have their own free tiers. The biggest cost drivers are typically $autocapture events, $pageview on high-traffic pages, and bot traffic. This skill covers specific techniques to reduce event volume without losing analytical value.
Prerequisites
- PostHog Cloud account with billing access
