About PostHog

PostHog is an all-in-one developer and product analytics platform built to give engineering teams complete visibility into user behavior and product performance. Designed to replace fragmented combinations of Mixpanel, Hotjar, LaunchDarkly, and Google Analytics, PostHog unifies product analytics, session recordings, feature flags, A/B testing, and user feedback surveys into a single integrated platform.

The platform integrates PostHog AI, an intelligent data assistant that helps developers write SQL queries, detects statistical anomalies in user conversion funnels, and summarizes hours of user session recordings into actionable takeaways. PostHog captures event telemetry automatically through autocapture scripts or explicit custom SDK events, giving teams retroactive insights without redeploying tracking code.

PostHog is open-source and provides a cloud-hosted SaaS platform as well as options for self-hosting on private cloud infrastructure. It offers a remarkably generous free tier providing 1 million analytics events and 5,000 session recordings free every single month, followed by transparent usage-based pricing.
