Observability & traceability
Apache-2.0 set of OpenTelemetry extensions from Traceloop that instrument GenAI applications non-intrusively in Python, TypeScript or Go and export traces either to Traceloop or to an existing observability backend. It is instrumentation plumbing: no access control, retention or evaluation features are part of the library.

Useful conversation with: Platform engineer, Observability lead.
Demonstrate exporting GenAI traces from my agent to my own OpenTelemetry backend, showing the workflow, task, agent and tool annotations.
Support labels reflect the supplied research. Documentation and vendor claims are not independent product tests. “Not established” means the researcher did not find support; it does not prove a capability is absent.
Documented by provider
OpenLLMetry is a set of extensions built on OpenTelemetry that provides observability over an LLM application with non-intrusive tracing, with Python, JavaScript/TypeScript and Go SDKs and documentation for annotating workflows, tasks, agents and tools.
Limit: The introduction does not state which attributes are captured per span, nor cost, token or evaluation support.
Documented by provider
Traces can be exported to Traceloop or to an existing observability stack, and the repository states the project is Apache 2.0 licensed under the traceloop organization with a companion OpenLLMetry-JS project.
Limit: No governance features (audit logs, RBAC, retention, redaction, certifications) are stated in either source.
Documented by provider
The repository states the project no longer logs or collects any telemetry in the SDK or instrumentations, and that any previously collected data was anonymous with no personally identifiable information.
Limit: Statement covers the library's own telemetry, not customer data handling by the Traceloop hosted service.
Listing does not imply partnership, supplier status, a working DutyGraph integration, or a compliance certification.
