About the Project

Why use this?

PostHog gives product and engineering teams a unified view of user behavior and release tooling. Teams can analyze funnels and retention, deploy feature flags, run experiments, replay sessions, and collect user feedback without integrating several vendors.

It is especially useful for SaaS and mobile product teams that want to connect product usage with experimentation and release management. PostHog offers both cloud and self-hosted deployment options.

Key Features

  • Product analytics, funnels, cohorts, and retention
  • Feature flags and A/B testing
  • Session replay and heatmaps
  • Surveys and user feedback
