Reviewer scorecard
“Simple to install but the data quality is limited. PostHog session replay is better for technical teams.”
“Observable Framework for data apps is excellent. Static site generation from data notebooks is the right approach.”
“Heatmaps and recordings reveal how users actually interact with designs. Essential for UX optimization.”
“The best platform for creating interactive data visualizations. D3 integration and the reactive model are powerful.”
“PostHog does everything Hotjar does plus product analytics. Consolidating tools is smarter than paying for both.”
“Observable Framework is the sleeper hit — build data dashboards as static sites with SQL and JavaScript.”
