This project is a JavaScript error tracking SDK and application performance monitoring tool. It captures runtime exceptions and crashes across web browsers, server-side environments, and edge computing contexts.
The SDK includes a session replay tool that records visual user interactions to reproduce bugs. To ensure telemetry delivery, it provides a tunneling proxy that routes monitoring data through custom endpoints to bypass browser-level ad blockers.
The toolkit also features a source map processor that translates minified stack traces back into original source code. Additionally, it covers structured application log capture and performance tracing to identify system bottlenecks via execution spans.
