PostHog vs Hotjar

Who This Page Is For

You’re comparing these tools because you want session recordings and you’re deciding between:

• All-in-one product analytics (PostHog: recordings + analytics + flags) vs UX optimization focus (Hotjar: recordings + heatmaps + feedback)
• Product teams (PostHog) vs UX/Marketing teams (Hotjar)
• Self-hosting option (PostHog) vs Cloud-only simplicity (Hotjar)

Both have session recordings. The question is what you need alongside them.

The Core Tradeoff

PostHog bundles session recordings with product analytics, feature flags, A/B testing, and surveys. Developer-focused. Self-hosting available.

Hotjar specializes in UX optimization — recordings, heatmaps, feedback widgets, form analysis. Simpler interface for non-technical teams. Cloud-only.

The decision: Need product analytics + recordings + flags? PostHog. Need UX-focused recordings + feedback for marketing/design? Hotjar.

Quick Decision

Choose PostHog when:

• You need product analytics alongside recordings (funnels, retention)
