Verdict
PostHog provides the most feature-rich open-source alternative, combining session replay with product analytics, feature flags, and A/B testing in a single platform.
What customers praise
Its generous free cloud tier (up to 1 million events and 15k recordings per month) and transparent, usage-based pricing are great for startups.
What customers criticise
As an all-in-one tool, its session replay feature is less mature and has fewer specific insights (like rage click detection) than dedicated competitors.
Best for
Technical teams and startups wanting an all-in-one, open-source product analytics suite with integrated session replay.
