Hotjar and PostHog are two of the most compared analytics tools for PMs — and they occupy different positions in the analytics stack. Hotjar is a behavioral visualization tool: heatmaps, session recordings, and user feedback surveys. PostHog is a full product analytics platform: funnels, cohorts, retention, experimentation, feature flags, AND session replay. Hotjar wins on heatmaps and qualitative feedback; PostHog wins on analytics depth, experimentation, and value. For most PMs, PostHog covers more ground. Here's a category-by-category breakdown.
The behavior visualizer. Best for PMs who need heatmaps, session recordings, and user feedback surveys. Free up to 35 sessions/day. From $32/mo (Plus). Winner for qualitative insights.
The all-in-one platform. Best for PMs who need analytics, funnels, experimentation, flags, AND session replay. Free up to 1M events/mo. Open source. Winner for breadth and value.

| Category | Hotjar | PostHog | Winner |
|---|---|---|---|
| Overall for PMs | Best for PMs who need heatmaps, session recordings, and user feedback — qualitative behavior insights | Best for PMs who need product analytics, funnels, experimentation, and session replay in one tool | posthog |
| Core strength | Behavioral visualization — heatmaps, session recordings, conversion funnels, form analytics | Product analytics — event tracking, funnels, cohorts, retention, experimentation, feature flags, session replay | tie |

| Product analytics (funnels, cohorts, retention) | Basic — conversion funnels and form analytics but no cohort analysis, retention curves, or deep event tracking | Full product analytics — funnels, cohorts, retention, lifecycle, stickiness, path analysis. Industry-grade. | posthog |
| Experimentation / A/B testing | No native experimentation — integrates with external tools | Built-in experimentation with feature flags, statistical significance, and Bayesian analysis — included free | posthog |
| Feature flags | No feature flags | Built-in feature flags — unlimited flags on free plan | posthog |
| User feedback | Built-in feedback — polls, surveys, and incoming feedback widget. Collect qualitative feedback directly. | No native feedback collection — focuses on behavioral data, not surveys | hotjar |
| Open source / self-host | No — proprietary, cloud-only | Yes — open source, self-hostable, full feature parity with cloud | posthog |
| Starting price (paid) | Free up to 35 sessions/day; Plus from $32/mo (billed annually) | Free up to 1M events/mo; pay-as-you-go at ~$0.00031/event after | posthog |
| Free tier | 35 sessions/day, 105 recordings/mo, basic heatmaps, 3 surveys, 5 feedback widgets | 1M events/mo, 5K session recordings, unlimited feature flags, unlimited team members, 1-year data retention | posthog |
| Best for PMs who… | Need qualitative behavior insights — heatmaps, recordings, and user feedback to understand why users behave certain ways | Need quantitative product analytics plus session replay — funnels, cohorts, experimentation, and recordings in one tool | posthog |
Hotjar wins on heatmaps and user feedback collection. PostHog wins on analytics depth, experimentation, feature flags, open source, and pricing. For most PMs, PostHog's all-in-one approach covers more ground at a lower cost.
A side-by-side breakdown — PostHog's free tier is more generous and its paid pricing is more cost-effective.
| Plan | Hotjar | PostHog |
|---|---|---|
| Free | 35 sessions/day, 105 recordings/mo, basic heatmaps, 3 surveys, 5 feedback widgets | 1M events/mo, 5K session recordings, unlimited flags, unlimited team, 1-year retention |
| Entry paid | $32/mo (Plus, billed annually) — 100 sessions/day, 300 recordings/mo, advanced heatmaps, unlimited surveys | Pay-as-you-go — ~$0.00031/event after free tier, transparent and predictable |
| Mid-tier | $80/mo (Business) — 500 sessions/day, 2K recordings/mo, AB testing integration, feedback dashboards | Included in pay-as-you-go — session replay, feature flags, experimentation all included |
| Enterprise | $171/mo (Scale) — 2,500 sessions/day, 10K recordings/mo, SSO, advanced security | Enterprise / self-hosted — SSO, audit logs, advanced permissions; self-host for free |
| Pricing model | Session-based — tiered by daily session count, predictable but limited by session volume | Event-based — pay-per-event, scales with usage, transparent pricing |
Key insight: PostHog's free tier (1M events, 5K recordings, unlimited flags) is dramatically more generous than Hotjar's (35 sessions/day, 105 recordings/mo). PostHog's pay-per-event pricing is transparent and scales smoothly; Hotjar's session-based tiers create hard limits. For PMs who need analytics + replay, PostHog is the value pick.

For most PMs, PostHog is the better choice. It includes product analytics (funnels, cohorts, retention), experimentation, feature flags, AND session replay — all in one tool with a generous free tier (1M events, 5K recordings). Hotjar is better if you specifically need heatmaps (click, move, scroll maps) and built-in user feedback collection (surveys, polls). PostHog covers more ground for PMs who need both behavioral insights and quantitative analytics; Hotjar is the focused choice for qualitative visualization. See our PostHog review and Hotjar alternatives guide.
No — PostHog does not have native heatmaps. It has session replay (watching real user sessions), but not the click/move/scroll heatmap visualization that Hotjar is known for. If heatmaps are a must-have for your team, Hotjar is the clear choice. Many PMs use both: Hotjar for heatmaps and qualitative feedback, PostHog for analytics and experimentation. For PMs who primarily need session replay (not heatmaps), PostHog's built-in replay is sufficient. See our AI product analytics tools guide.
PostHog is more cost-effective. PostHog's free tier includes 1M events/mo, 5K session recordings, unlimited feature flags, and unlimited team members. Paid pricing is pay-per-event at ~$0.00031/event — transparent and predictable. Hotjar's free tier includes 35 sessions/day and basic heatmaps. Hotjar's paid plans start at $32/mo (Plus, billed annually) and scale to $171/mo (Scale). For PMs who need analytics + replay, PostHog's free tier alone covers more than Hotjar's paid plans. See our free AI tools guide.
No — Hotjar cannot replace PostHog for product analytics. Hotjar provides heatmaps, session recordings, and basic conversion funnels, but it lacks the deep analytics that PostHog offers: cohort analysis, retention curves, lifecycle analysis, event-based tracking, experimentation, and feature flags. Hotjar is a qualitative behavior visualization tool; PostHog is a full product analytics platform. For PMs who need both qualitative and quantitative insights, using both is the right approach — or using PostHog alone if heatmaps aren't critical. See our Amplitude vs PostHog comparison.
Yes — PostHog has built-in session replay that lets you watch real user sessions, see clicks, rage clicks, and errors. It's included in the free tier (5K recordings/mo). PostHog's session replay is integrated with its analytics, so you can filter recordings by funnel drop-off, cohort membership, or feature flag — which is more powerful than Hotjar's standalone recordings. For PMs who need session replay, PostHog's integrated approach is a significant advantage. See our PostHog review.
It depends on your needs. If you need heatmaps and user feedback surveys (which PostHog doesn't have), use both: Hotjar for qualitative visualization and PostHog for analytics + replay. If you don't need heatmaps, PostHog alone covers session replay, analytics, experimentation, and feature flags — making Hotjar unnecessary. For PMs on a budget, start with PostHog's free tier and add Hotjar only if you find you need heatmaps or survey collection. See our Hotjar vs FullStory comparison.
They solve different problems. Hotjar and PostHog are analytics tools that help you measure and understand user behavior.
