Traceloop
OpenTelemetry-native observability for LLM and agent workloads.
Open source
Best when platform teams already run OpenTelemetry and want LLM spans in existing backends.
Selection advice
Choose Traceloop when your SRE stack is already OpenTelemetry-centric and LLM traces should look like normal service telemetry.
Best for
- OpenTelemetry-first agent tracing
- exporting spans to Datadog or Grafana
- standardized instrumentation across services
Not ideal for
- teams without an observability backend
- projects that want an all-in-one eval UI on day one

Minimal implementation shape
Enable OpenLLMetry in your agent service, export spans to your collector, and alert on tool-call error rates like any other microservice.
