Pick PostHog if your primary need is event-based product analytics (funnels, retention, cohorts, A/B testing, feature flags) and session replay is one capability among many. They're open-source, self-hostable, well-funded, and the dev community is strong. For engineering-led product teams, this is often the right answer.
Visit PostHogPick Replayful if you want a focused replay tool without learning a full analytics platform. We don't ship A/B testing, feature flags, or custom event schemas. The dashboard is built around 'find the replay that explains this number'. Faster to install, less surface area. Trade-off: way less product depth.
