PostHog
All-in-one product analytics, feature flags, and A/B testing
PostHog is the open-source product analytics platform that replaces multiple tools. Product analytics, session replay, feature flags, A/B testing, error tracking, and surveys—all in one platform. With 25K+ GitHub stars, it's the choice of companies who want full control over their product data without vendor lock-in.
Why PostHog?
Building a modern product stack means juggling multiple analytics tools. Google Analytics for traffic, Amplitude for product analytics, LaunchDarkly for feature flags, Optimizely for A/B tests. Each tool has its own pricing, data format, and learning curve. You're paying for overlap while missing the unified view your team needs to ship faster.
How It Works
PostHog consolidates your entire product stack into one platform. Install once, and get product analytics, session replay, feature flags, experiments, and surveys. All data lives in one place, so you can see exactly how users behave, roll out features safely, and measure impact without switching between tools or reconciling data.
What Is PostHog?
PostHog is an open-source product analytics platform. It provides event analytics, session replay, feature flags, A/B testing, error tracking, surveys, and data pipelines. Self-host for complete data control or use the cloud with a generous free tier.
