What PostHog actually does
PostHog is an open-source suite designed for tracking user behaviour within digital products. It combines analytics, session recordings, feature flags, and A/B testing into a single platform that you run on your own infrastructure.
Best fit: Teams looking to consolidate multiple third-party product analytics and experimentation tools into a single self-hosted platform.
Worth knowing: Running a comprehensive analytics platform locally requires substantial server resources and operational overhead compared to using managed cloud services.
Deployment notes
As a Python-based application, it typically requires a persistent database backend, a message queue, and a reverse proxy to handle TLS termination in production.
