PostHog
Open-source product analytics with session replay and feature flags
Overview
PostHog combines the tools that product teams need into a single open-source platform: event analytics, session replay, feature flags, A/B testing, and surveys. Instead of paying for five separate tools and dealing with data synchronization issues, everything lives in one place.
The self-hosting option makes PostHog unique among product analytics tools. Deploy on your own infrastructure and your user data never leaves your servers - a requirement for healthcare, finance, and other regulated industries. The open-source model also means no vendor lock-in.
For product-led growth teams, the combination of analytics and feature flags is powerful. Ship a feature behind a flag, gradually roll it out, measure its impact with built-in analytics, and make decisions with data - all within the same platform.
