Fullstory
Pros
- Autocapture technology eliminates the need for manual event tagging, capturing every interaction automatically

- StoryAI proactively surfaces friction points and prioritizes opportunities by conversion impact, reducing manual analysis
- Unified analytics across web, iOS, Android, and cross-platform frameworks in a single view
- Lightweight mobile SDK with ~100KB per minute bandwidth usage, minimizing performance impact
Cons
- No transparent pricing or free tier available; requires contacting sales for all plans

- 2-year data retention cap on Team and Business plans requires Custom tier for longer storage
