In-depth: PostHog vs Hotjar
Contents
PostHog and Hotjar both help you understand how users interact with your product through session replay, heatmaps, and user surveys. They're popular choices for teams that want to go beyond pageview analytics and see what users actually do.
Hotjar is now part of Contentsquare (which also acquired Heap). It's still available as a focused user research tool built for UX teams, but pricing and plans now live under the Contentsquare umbrella.
PostHog combines replays and surveys with a full suite of developer tools designed to measure impact from one integrated platform.
In this comparison, we break down how PostHog and Hotjar stack up so you can decide which one is the right fit.
How is PostHog different?
1. We're an all-in-one platform
PostHog goes beyond replays and user surveys by integrating them with product and web analytics, feature flags, A/B testing, error tracking, LLM analytics, workflows, a data warehouse, data pipelines, and more. It's everything you need from a single app with a single contract. A genuine single source of truth for your product and customer data.
2. It's a platform built for developers
This means you get support from the engineers who actually build the product, extensively documented APIs, and a SQL query builder, so you can analyze data how you want. Our code, culture, and strategy are public on GitHub and in our public handbook.
And as your needs grow, PostHog grows with you – advanced capabilities such as a CDP or data warehouse are ready to switch on whenever you need them.
Development teams at Supabase, Lovable, and ElevenLabs, and many more trust PostHog as they scale.
3. We're cheaper and have a generous free tier
Every customer gets 5,000 web recordings, 1,500 survey responses, and 1 million events for free each month, no matter what plan they're on. Our generous free tier means more than 90% of companies use PostHog for free, and you'll pay less when you do use up your free credits. You also get 2,500 free recordings on mobile apps.

Product comparison
The best way to imagine PostHog is as an alternative to Hotjar, Heap, and LaunchDarkly rolled into one.
Analytics
Since Hotjar is now part of Contentsquare, the analytics picture has changed.
Hotjar already offered funnels, but since the merge, broader product analytics features – like retention, user paths, and custom dashboards – are now available through Contentsquare's plans.
Contentsquare splits analytics across two products: Experience Analytics (funnels, heatmaps, dashboards – 200k free monthly sessions) and Product Analytics (trends, retention, journey analysis – 10k free monthly sessions). A significant number of features like user ID and custom variable filters, session summaries, and their AI assistant are all on their paid Growth tier or higher.
PostHog includes all of this and more in a single product, with 1 million free events every month.
Session replay
Session replays are an essential tool for understanding how people use your product, especially for early-stage companies searching for product-market fit.
Since joining Contentsquare, Hotjar's session replay capabilities have expanded – recordings now include AI-powered summaries, error detection, and frustration signals. Mobile app session replay is also available through Contentsquare's Enterprise plan.
PostHog supports mobile session replay with 2,500 recordings free every month, including Android, iOS, React Native, and Flutter.
Both PostHog and Hotjar are good options if you're looking for a FullStory, LogRocket, or Microsoft Clarity alternative.
Heatmaps
Heatmaps visualize where people click and navigate to on your app or website and, when combined with session replay, give a clearer overview of how users behave.
Surveys
Hotjar's surveys are now part of Contentsquare's Voice of Customer product. They've added AI-generated surveys, AI summary reports with sentiment analysis, and increased free response limits.
Hotjar still supports more survey types than PostHog, including unmoderated user tests and interview scheduling, but PostHog offers more precise targeting options.
Price comparison
Hotjar's old pricing tiers (Business and Scale) no longer exist. Since the Contentsquare merger, Hotjar's tools are now sold under Contentsquare's pricing structure, which is split across three separate products – Experience Analytics (replays, heatmaps), Voice of Customer (surveys, interviews), and Product Analytics (powered by Heap). Each product has its own plan: Free, Growth, Pro, or Enterprise.
PostHog, by contrast, has fully transparent, usage-based pricing for every product on a single bill.
Free tier comparison
| Contentsquare | PostHog | |
|---|---|---|
| Session replays | 10,000/mo | 5,000/mo |
| Heatmaps | 200,000/m (with sessions) | Included with replays |
| Analytics events | 10,000 sessions (Product Analytics) | 1,000,000 events |
| Survey responses | 100/mo | 1,500/mo |
| Data retention | 1 month (Experience Analytics) | 7 years |
| Feature flags | ❌ | 1,000,000 requests |
| A/B tests | ❌ | 1,000,000 requests |
| Error tracking | ❌ | 100,000 requests |
Contentsquare does offer 200,000 monthly sessions for its Experience Analytics free plan, which is generous for heatmaps and basic session data. But its Product Analytics free tier is limited to just 10,000 sessions with limited history, and surveys cap at 100 responses per month.
PostHog gives you 1 million analytics events, 5,000 web replays, 2,500 mobile replays, 1,500 survey responses, and 1 million feature flag requests – all on the same platform.
Paid pricing
PostHog uses usage-based pricing across all products. You only pay for what you use, and prices decrease at higher volumes. Here's what typical usage costs with PostHog:
| Monthly usage | PostHog cost |
|---|---|
| 5,000 replays | $0 (free tier) |
| 15,000 replays | $50 |
| 50,000 replays | $157.5 |
| 100,000 replays | $161.5 |
| 1,500 survey responses | $0 (free tier) |
| 2,500 survey responses | $50 |
| 5,000 survey responses | $122.50 |
| 1M analytics events | $0 (free tier) |
| 5M analytics events | $137.2 |
Contentsquare's Growth plan starts at $40/month for Experience Analytics, $79/month for Voice of Customer (which includes surveys), and it's not disclosed for Product Analytics. Because replays, surveys, and analytics are billed as separate products, costs add up quickly once you need more than one tool. Pro and Enterprise pricing is custom and require a conversation with the sales team.
With PostHog, everything is on one bill with one pricing calculator. You can see exactly how much you'll pay using the calculator on our pricing page.
Platform and integrations
Data sources
PostHog has a built-in data warehouse, so you can import, combine, and analyze data from multiple sources, and combine it with analytics events. This means you can monitor deal counts using data from Hubspot, analyze gross revenue using Stripe data, and track support ticket SLAs using Zendesk data, all from within PostHog.
