Everything you need to build successful products
Product Analytics
Understand what your users are doing. Build funnels, user paths, and retention cohorts with a few clicks.
Explore Analytics →Session Replay
Watch real users interact with your app. Debug issues faster and understand where users get stuck.
Explore Replay →Feature Flags
Safely roll out new features to a percentage of users, specific cohorts, or just your internal team.
Explore Flags →A/B Testing
Test changes before you commit. Run experiments to see how new features impact your key metrics.
Explore Testing →We're open source and community-built
PostHog is built by a team of engineers who wanted a better way to understand product usage without sending all our data to third parties. We build in the open, and our roadmap is public.
