What Are Replay Sessions?

PlayerZero’s Replay Sessions provide end-to-end visibility into user sessions, combining user behavior, DOM state, developer tools data, and distributed system traces. These reports give engineers and support teams a unified, actionable view of what happened, why, and where to fix it.

​
End-to-End Context Capture

  • Captures every interaction, including:
    • Clicks, navigations, form submissions, and scrolls.
    • Automatic detection of rage clicks.
    • Reconstructs the full navigation flow to visualize the exact steps to reproduce.
  • Full page state capture at critical moments, including:
    • Incremental DOM changes as they occur.
    • Shadow DOM and canvas capture support.
    • Configurable privacy masking (Relaxed, Normal, or Strict) to safeguard sensitive data.
  • Integrated developer diagnostics, including:
    • Complete console logs (errors, warnings, debug messages).
    • Network request monitoring with performance thresholds.
    • Automatic JavaScript error capture with full stack traces.
    • Browser and device details, system performance metrics.
  • Correlates frontend and backend logs into a single timeline via trace IDs.
  • Provides real-time filtering by severity, user, or time range.
  • Streams logs for:
    • Console messages
    • API calls
    • Database queries
    • System metrics
  • Visualizes end-to-end request flow with:
    • Span trees showing service-to-service calls.
    • Performance breakdowns highlighting bottlenecks.
    • Error highlighting to pinpoint failure points.
    • Network diagrams mapping system dependencies and impacts.

​
Launch AI Directly from Session Data

  • Launch AI investigation on any network request or error span with full session context.
  • The AI connects the dots between logs, traces, and your codebase automatically.
  • One-click AI correlation between user problems and specific files/functions.
  • The AI suggests:
    • Exact file locations
    • Relevant code explanations
    • Potential fixes and test strategies
  • Start an investigation directly from any point in a user journey.
  • The AI reconstructs the flow, showing how actions led to specific errors or states.

​
QA Widget “Debug Button”

  • A shareable DevTools widget with hover animation for quick session capture.
  • Generates direct links for instant access to:
    • Debug traces
    • Session timelines
    • Key issue data
