Summary

PostHog is a platform for product development, customer communication, and understanding customer data. Its analytics tools cover product and web activity, funnels, heatmaps, trends, lifecycle analysis, and user paths. Session Replay records sessions from web, React Native, iOS, Android, Flutter, and other SDKs. Feature Flags can target users, groups, or traffic shares, with phased rollouts, kill switches, variants, JSON payloads, and beta opt-ins. An integrated data warehouse can connect to external sources such as Snowflake or BigQuery, while its event pipeline transforms data in real time and routes it to more than 50 destinations. PostHog Desktop is a coding agent that can use product signals to investigate issues and create pull requests. A free plan includes one year of event and metadata retention and one month of recording retention; paid plans guarantee seven years of event and metadata retention. PostHog also describes an MIT-licensed open-source product.
