Frequently Asked Questions
What is the best free session replay tool with no recording limits? +
Microsoft Clarity is the best free session replay tool with no session cap. It's genuinely free with no paid tier required and no daily recording limit. Hotjar's free tier is too restrictive (35 sessions/day) for any real production app.
Do session replay tools affect page load speed? +
All session replay tools add a script to your page. Microsoft Clarity and Hotjar both load asynchronously and have minimal impact on Core Web Vitals. FullStory's script is heavier due to autocapture of all DOM interactions. Clarity is consistently the lightest of the three.

All three support GDPR compliance with PII masking and IP anonymization. Hotjar is SOC 2 Type II certified. Microsoft Clarity runs on Azure infrastructure with Microsoft's enterprise compliance stack. FullStory is SOC 2 Type II certified and offers data processing agreements for enterprise customers.
