“10-100x faster than pandas with better syntax. Lazy evaluation and parallel execution are game-changing for large datasets.”
“Heatmaps and recordings reveal how users actually interact with designs. Essential for UX optimization.”
“PostHog does everything Hotjar does plus product analytics. Consolidating tools is smarter than paying for both.”
