- Click, scroll, and movement heatmap aggregations
- In-app micro-surveys and star rating feedback widgets
- Frustration signal logging (rage clicks and dead clicks)
- Basic URL-based conversion funnel visualization
what you lose
- Turnkey PII input field auto-masking compliance
- Hotjar Engage user interview recruitment and scheduling
- Zero-maintenance auto-scaling ingestion architecture
- SOC2 Type II data security compliance out-of-the-box
- Consolidated analytics dashboard covering observe, ask, and engage
real moats
- Storage efficiency pipelines for high-volume uncompressed DOM mutation blobs
- SOC2 and enterprise data privacy compliance guarantees
