Context Propagation And Request Tracing

via “distributed tracing with automatic parent-child span linking”

Open-source LLM observability — tracing, evaluation, OpenTelemetry, span analysis.

Unique: Automatic parent-child span linking via contextvars (Python) and async context (JavaScript) without requiring manual trace ID propagation in application code, reducing instrumentation boilerplate

vs others: Simpler than Jaeger's manual trace ID propagation because context is automatically threaded through async calls; more reliable than implicit correlation because parent-child relationships are explicit in span data
