Posthog

PostHog is an open source, developer-focused product and data platform that helps teams understand user behavior, validate product changes, and ship better software. By bringing product analytics, session replay, feature flags, experimentation, and customer data capabilities into an integrated toolkit, PostHog shortens the loop from insight to iteration while keeping teams in control of how data is collected and used. PostHog is redefining the standard for product-led growth by putting powerful, actionable insights directly into the hands of builders.
