Reviewers mostly praise PostHog as a developer-friendly, all-in-one toolkit for product analytics, session replays, feature flags, funnels, and experiments. They say it is quick to integrate, flexible for event tracking, and useful for digging into user behavior, UX issues, drop-off, and rollout control without stitching together multiple tools. Users also highlight open-source flexibility, self-hosting, strong docs, and a responsive team. A few caveats appear: the UI could be more polished, it may be heavier for non-technical teams, and some find it less feature-rich than Google Analytics.
