What is PostHog?
PostHog is an all-in-one platform built specifically for product engineers who want to build, test, measure, and ship better software—faster. Instead of juggling dozens of separate tools for analytics, bug tracking, feature releases, and user behavior, PostHog brings everything together in a single workspace that acts like a co-pilot for both you and your AI agents.
What makes PostHog different? It’s not just another analytics dashboard. It’s a full Product OS that includes session replay, feature flags, product analytics, revenue tracking, and even a built-in data warehouse—all designed so engineers can move quickly without waiting on other teams or stitching together disconnected data sources.
What are the features of PostHog?
- Product Analytics: Track user behavior, conversion funnels, and engagement across your app with real-time event data.
- Session Replay: Watch actual user sessions to see exactly how people interact with your product—and where they get stuck.
- Feature Flags: Safely roll out new features to specific users or segments without deploying new code.
- AI-Powered Insights: Ask natural language questions about your data and let PostHog AI summarize findings, debug issues, or even suggest experiments.
- Built-in Data Warehouse: Store and query all your product, payment, support, and error data in one place—no external pipelines needed.
- Heatmaps & User Paths: Visualize clicks, scrolls, and navigation flows to understand usability at a glance.
- Usage-Based Pricing: Pay only for what you use, with generous free tiers (most teams never pay a dime).
What are the use cases of PostHog?
- Diagnose why users drop off during onboarding by combining funnel analysis with session replays.
- Test a new pricing page by launching it behind a feature flag for 10% of users, then measure conversion impact.
- Investigate a spike in errors by correlating backend traces with user behavior in the same interface.
- Understand how AI-powered features are being used by tracking custom events tied to generative actions.
- Replace multiple tools (like Mixpanel, FullStory, and LaunchDarkly) with one unified platform.
- Give non-technical teammates self-serve access to product data through intuitive dashboards and AI queries.
