Could you build this?
Partial While wrapping rrweb and injecting W3C trace headers into browser requests is straightforward, building an ingestion backend that accurately correlates high-volume distributed spans with DOM replay frames in a synchronized scrubber is difficult.
What it would actually take: The system requires a browser SDK monkey-patching fetch/XHR to inject trace IDs into rrweb metadata streams, an OpenTelemetry ingestion pipeline storing spans in a columnar store like ClickHouse, and object storage for session chunks. Building the unified scrubber requires complex front-end timeline synchronization that accounts for clock drift and asynchronous network spans.
