Features

• Application Performance Monitoring - Tracks execution flow and operation duration to identify bottlenecks and optimize response times in JavaScript apps.
• Telemetry Data Pipelines - Implements a telemetry pipeline to collect errors and performance spans for asynchronous transmission.
• Source Map Resolution - Translates compressed stack traces into original source code by processing uploaded source maps.
• Error Reporting - Captures and reports runtime exceptions across browsers and server-side environments in real time.
• Error Tracking - Captures runtime exceptions and crashes across web, server-side, and edge computing environments.
• Source Map Deobfuscators - Maps minified production stack traces back to original source code using uploaded source map files.
• Browser Tracing - Wraps native APIs to measure execution duration and establish span relationships for performance tracing.
• Application Logging - Records structured log messages at various severity levels to track system behavior.
• Session Recording - Provides visual recording of user interactions to help reproduce bugs and analyze behavior leading to crashes.
• Session Replay Tools - Records visual interactions and user behavior to reproduce bugs through session playback.
• Session Reconstruction - Tracks DOM changes via MutationObservers to serialize UI state for visual session replay.
