Reviewer scorecard
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“Write analytics once, send to every tool. The destination catalog and identity resolution are genuinely valuable.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“Absurdly expensive at scale. RudderStack is the open-source alternative that does the same job.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
“Customer data infrastructure is essential but commoditizing. Segment's Twilio integration creates a unique data + communication platform.”
