Posthog

PostHog is an open-source product operating system platform that equips engineers with comprehensive tools to ensure they are developing desirable products. Our platform encompasses essential features such as product analytics, video replays, feedback tools, feature flags, and experimentation. With PostHog, you have the flexibility to deploy it to the cloud or self-host it on your existing infrastructure, eliminating the need to share data externally. Born as an open-source project during Y Combinators W20 cohort, PostHog achieved the most successful B2B software launch on HackerNews since 2012, even at just four weeks old.
