Panel Reviews
The Builder
Developer Perspective
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
The Skeptic
Reality Check
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
The Futurist
Big Picture
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
Community Sentiment
“Session replay + feature flags + analytics in one self-hosted tool is genuinely unbeatable”
“Replaced Mixpanel and LaunchDarkly with PostHog and cut our analytics bill by 80%”
“PostHog's feature flags with gradual rollouts changed how our team ships to production”
“The all-in-one approach works — heatmaps, funnels, A/B testing, all from one SDK snippet”
