Pricing Comparison (2026)

• Plus: ~$39/month, 100 daily sessions
• Business: ~$99/month, 500 daily sessions
• Scale: Custom pricing, 4,000+ daily sessions

Hotjar becomes expensive as traffic grows because pricing is tied to sessions, not outcomes. High-traffic sites often outgrow the Business plan quickly.

What Each Tool Does Best

Hotjar: Fast Qualitative Insights

Hotjar's biggest strength is speed. You can install the script, record sessions, and launch a survey in the same day. The heatmap and recording UI is intuitive, and the survey builder is more flexible than most analytics tools.

** standout features:**

• Incoming feedback widget for in-the-moment reactions
• Visual feedback on recordings
• Easy sharing of highlight reels

Weakness: Limited quantitative analytics. Hotjar shows you what users do, but not always why at scale.

FullStory: Digital Experience Analytics

FullStory treats every session as a structured dataset. You can search sessions by behavior, segment users by actions, and quantify the revenue impact of errors or friction.

Standout features:

• Rage click and error click detection
• Session search by event, element, or frustration signal
• Journey mapping and conversion analytics

Weakness: Higher price and steeper learning curve. It is overkill for teams that just want replay.

PostHog: All-in-One Growth Platform

PostHog combines the best of product analytics and session replay with experimentation infrastructure. Because everything is in one warehouse, you can run an A/B test, see the funnel, and watch recordings of users in the losing variant without switching tools.

Standout features:

• Product analytics + replay + feature flags + A/B tests + surveys
• Generous free tier
• Open-source and self-hostable
• Strong cohort and retention analysis

Weakness: The breadth can be overwhelming. Teams that only need replay may find the extra features distracting.
