Pros & Cons

FullStory

Pros
✓ Best-in-class autocapture technology — captures every click, scroll, and interaction without manual event tagging, enabling retroactive analysis on historical data
✓ Frustration signals (rage clicks, dead clicks, error clicks) surface UX problems automatically, saving PMs hours of manual session review
✓ Powerful search and segmentation — find specific user sessions by any combination of events, user properties, or frustration signals in seconds
✓ Strong privacy-by-design approach with automatic PII masking, excluded elements, and HIPAA-compliant configurations for regulated industries
Cons
✗ No transparent public pricing — Business and Enterprise plans require contacting sales, making budgeting difficult for smaller teams
✗ Session-based pricing can become very expensive at scale, especially for high-traffic consumer products with millions of monthly sessions
✗ Data retention on lower tiers is limited — teams may lose access to historical sessions unless on Enterprise plans

Sentry

Pros
✓ Industry-leading error tracking with intelligent issue grouping that automatically deduplicates and categorizes errors across releases
✓ Open-source core with a self-hosted option — rare for observability tools and ideal for teams with strict data residency requirements
✓ Broad SDK support covering 100+ platforms and languages including JavaScript, Python, Ruby, Go, Java, React Native, Flutter, and Unity
✓ Session Replay feature provides visual context alongside stack traces, dramatically reducing debugging time
Cons
✗ Event-volume pricing can become expensive at scale — high-traffic applications can burn through quotas quickly and incur overage charges
✗ Alert fatigue is common without careful tuning — default configurations generate excessive noise for large codebases
✗ Not a project management tool — requires integration with Jira, Linear, or GitHub Issues for issue tracking workflows
