Session Recording Tools: FullStory vs Hotjar vs Microsoft Clarity

№ 01Microsoft Clarity: free, unlimited, surprisingly good

Clarity is Microsoft’s session-recording product. Free, no session cap, no time limit. Features: full session replay, click heatmaps, scroll heatmaps, “rage clicks” / “dead clicks” / “excessive scroll” flags, segmentation by device/source/page, integration with GA4.

The catch (and it’s small): Microsoft uses the aggregated data to train Bing/Clarity insights. The privacy policy is reasonable; PII is masked by default. For most mid-market B2B sites, this trade is fine. For 90% of mid-market use cases, Clarity is the right answer — full stop.

№ 02Hotjar: pay for the survey + feedback widgets

Hotjar costs $39-$389/mo depending on session volume. Core session replay and heatmap features are comparable to Clarity. The value-add: integrated survey widgets, on-page feedback prompts, post-conversion micro-surveys, recruitment for moderated UX research.

If you’re running on-page surveys and customer feedback loops as a regular practice, Hotjar consolidates the tool stack. If you’re not, Clarity does the recording work for free. Don’t pay for Hotjar’s recording — pay for the integrated qualitative layer or use Clarity.

№ 03FullStory: real-time, real expensive

FullStory ($299+/mo, custom-quoted for high volume) is the premium tier. Differentiators: real-time recording (Clarity has 1-2 hour delay), advanced search (“show me users who clicked X then Y then Z”), integrated developer tools for SaaS apps, frustration signal scoring, Funnel analytics built-in.

FullStory pays back at scale — SaaS apps with complex flows, e-commerce with 100K+ monthly sessions, dedicated CRO teams that need real-time investigative power. For a 5K-30K session mid-market B2B service site, FullStory is overkill. The capability delta over Clarity doesn’t justify the $3,600/year delta.

№ 04The honest decision matrix

The recommendation we make to every Tampa mid-market client:

• Under 30K sessions/month, lead-gen B2B: Microsoft Clarity. Free. Done.
• 30K-100K sessions/month, B2B SaaS with self-serve flows: Hotjar Plus or Business tier ($59-$129/mo). The survey integration earns its keep.
• 100K+ sessions/month, complex SaaS UX, dedicated CRO team: FullStory. The real-time investigation and developer tools save more hours than they cost.
• E-commerce with checkout complexity: FullStory or Mouseflow ($31+/mo) for the conversion-funnel native features.

№ 05Privacy and compliance considerations

All three tools mask PII by default but the implementations differ. Clarity masks form field values out of the box. Hotjar requires CSS classes on sensitive fields. FullStory has more granular masking but more configuration.

For HIPAA or financial-services clients, all three require additional configuration and BAA (FullStory offers BAA; Clarity does not). For most B2B mid-market, default masking is sufficient. Don’t skip the GDPR/privacy-notice update — mention session recording in your privacy policy with a clear opt-out.

⚠What to avoid

• Buying FullStory before exhausting Clarity. Most mid-market sites never hit the use case that justifies the price delta.
• Skipping privacy policy updates after adding session recording. GDPR and CCPA both require disclosure. Easy to miss; non-trivial to defend.
• Watching session recordings without a hypothesis. You’ll spend 4 hours watching strangers click around and produce no actionable output. Watch with a question.
