How it works

Tracking User Behavior

Users integrate PostHog by installing an SDK (e.g., JavaScript, React, Python) into their application. The SDK automatically captures events like pageviews and user interactions, or developers can manually capture custom events using simple API calls (e.g., posthog.capture('Plan purchased')). This data is sent to the PostHog platform for analysis.

Analyzing Product Performance

Product teams use the PostHog UI to create insights from the captured data. They can build funnels to analyze conversion rates, view trends and graphs, explore user paths, and use SQL to write custom queries for advanced analysis. Session replays allow them to watch real user sessions to identify pain points.

Testing and Deploying Features

Developers use feature flags to deploy new features to specific user segments. They can run A/B tests (Experiments) to compare different versions of a feature and measure their impact on key metrics. Surveys can be deployed to collect qualitative feedback directly within the product.
