Contentsquare vs PostHog

Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

What drives the bill

The metric that actually scales your invoice.

Since absorbing Hotjar, Contentsquare sells three separately billed product lines — Experience Analytics, Voice of Customer and Product Analytics — with a free entry tier and quote-based paid plans. Enterprise annual contracts are priced by traffic and are typically six figures at scale.

Usage-based pricing per product with a substantial free tier; most small teams stay free indefinitely.

Free tier

There is now a free Contentsquare plan — it replaced Hotjar's as the self-serve entry point and is considerably more generous than Hotjar's old 35-sessions-a-day limit.

Large monthly free allowance across every product, plus free self-hosting.

Strengths

  • Revenue attribution turns UX findings into business cases executives act on.
  • Zone-based analysis is more actionable than raw heatmaps on complex pages.
  • Handles very high traffic volumes without sampling.
  • Replaces four or five separate subscriptions with one bill and one SDK.
  • Free tier is large enough for real production use at startup scale.
  • Open source with a credible self-hosting path.

Limitations

  • The full platform is expensive, and paid tiers are quote-based rather than published.
  • Substantial implementation and training effort before value appears.
  • Splitting the old Hotjar bundle into three separately billed lines means you may need more than one to replace what Hotjar did.
  • Individual modules are less deep than category specialists.
  • Self-hosting at scale is a serious infrastructure undertaking.
  • The product surface changes fast, which means occasional churn.

Best for

Large e-commerce, travel and financial organisations with dedicated optimisation teams — and now, via the free tier, the small teams Hotjar used to serve.

Startups and scale-ups consolidating analytics, replay and flags into one platform.

All of these integrate with: Snowflake.
