Session Replay

Capture visual recordings of user sessions for debugging.

When to Use

Reproducing hard-to-debug issues
Understanding user confusion
QA and support investigations

Privacy Requirements (Must Do)

Mask by default:

All text input fields
Passwords and sensitive data
User-generated content
Financial information
User photos/documents

Performance Budget

Resource	Limit
CPU	<5% additional
Memory	<20MB additional
Network	Batch on WiFi
Battery	Pause when low

Capture Strategies

Strategy	Fidelity	Overhead
Screenshots (1-2 fps)	Lower	Lower
View hierarchy recording	Higher	Moderate
Hybrid (screenshots + events)	Best	Moderate

Best Practice

Don't record everything. Target:

Error sessions only (rolling buffer)
Key user journeys
1-10% sampling for general insights
