Reviewer scorecard
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“Observable Framework for data apps is excellent. Static site generation from data notebooks is the right approach.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“Observable Framework is the sleeper hit — build data dashboards as static sites with SQL and JavaScript.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
“The best platform for creating interactive data visualizations. D3 integration and the reactive model are powerful.”
