Short answer: Microsoft Clarity is genuinely free with no session-recording volume cap, making it the default choice for budget-conscious teams or high-traffic sites where Hotjar's paid tiers would get expensive fast; Hotjar's paid plans add a more mature survey tool, on-site feedback widgets, and more advanced filtering and segmentation that Clarity doesn't match feature-for-feature. Many teams get the most value running Clarity for unlimited recording and Hotjar specifically for surveys, rather than treating it as strictly either-or.
1. Where Clarity genuinely wins
Zero cost with no session-volume cap is a real, structural advantage, most session-recording and heatmap tools, Hotjar included, throttle free usage by session count, which becomes a real constraint on any site with meaningful traffic. For a high-traffic site or a budget-constrained team, Clarity removes that constraint entirely rather than just delaying it to a paid tier.
2. Where Hotjar genuinely wins
Hotjar's paid tiers include a more developed survey and feedback-widget toolset, letting a team collect direct, in-context visitor feedback alongside the behavioral recording data, and its filtering and segmentation options for reviewing recordings are generally more advanced. For a team doing structured, ongoing CRO work rather than occasional spot-checks, this extra depth often justifies the cost.
| Factor | Microsoft Clarity | Hotjar |
|---|---|---|
| Cost | Free, no session cap | Free tier capped; paid tiers scale with usage |
| Session recording and heatmaps | Included, solid core feature set | Included, similarly solid |
| On-site surveys and feedback widgets | Limited compared to Hotjar | More mature, dedicated tooling |
| Recording filtering and segmentation | Basic | More advanced on paid tiers |
| Best fit | High-traffic or budget-constrained teams | Teams running structured, ongoing CRO programs |
3. The question that actually decides it
If the immediate need is simply watching real user sessions and heatmaps without worrying about a volume cap, Clarity covers that completely at zero cost. If the CRO work also needs structured on-site surveys, deeper segmentation of recordings, or a more mature reporting workflow, Hotjar's paid tiers earn their cost. Running both, Clarity for volume, Hotjar for surveys, is a legitimate middle path rather than a compromise.
4. What to check before choosing
- Actual monthly traffic volume, since this is where Hotjar's free-tier cap becomes a real constraint fastest.
- Whether structured on-site surveys are part of the CRO workflow, or whether session recording and heatmaps alone are enough.
- Budget reality: Clarity removes cost as a variable entirely, which matters for early-stage teams especially.

FAQ
Is Microsoft Clarity actually free, or does it have hidden limits?
Clarity is genuinely free with no session-volume cap, which is unusual among session-recording tools, but it's lighter on features than Hotjar's paid tiers, without a native survey or feedback-widget tool built in the same way, so the tradeoff isn't a hidden usage limit, it's a narrower feature set in exchange for zero cost.
- Clarity's free tier genuinely has no session cap, which is the main reason teams pick it.
- The tradeoff is feature depth, not a hidden volume limit.
Can I run Hotjar and Clarity at the same time on the same site?
Yes, technically both tools can be installed simultaneously without conflict, and some teams do run Clarity for its unlimited, free session recording alongside Hotjar specifically for its survey and feedback-widget features, effectively using each tool for what it does best rather than treating the choice as strictly either-or.
- Running both isn't technically a conflict, and some teams do exactly this.
- This works best when each tool is used specifically for its strongest feature, not duplicated coverage.
