Hotjar

4.5 / 5800 reviews

+ Heatmaps and session recordings make user behavior instantly visual and understandable

+ Dead simple to install and start getting insights

- Session recording limits on free and lower tiers can be restrictive

“Hotjar showed us that users were completely ignoring our CTA button. One heatmap told us more than a month of A/B testing data.”

PostHog

4.5 / 5250 reviews

+ All-in-one: analytics, session replay, feature flags, A/B testing, and surveys

+ Generous free tier and open-source self-hosting option

- UI can feel overwhelming with so many product areas

“PostHog replaced Mixpanel, LaunchDarkly, and Hotjar for us. One tool, one bill, and we can self-host if we ever need to.”
