Traceloop

Traceloop provides observability for LLM and GenAI applications through its open-source OpenLLMetry SDK, which extends OpenTelemetry to capture traces, latency, and cost data. It offers automatic instrumentation for 20+ model providers, vector databases, and frameworks such as LangChain, LlamaIndex, and CrewAI. Collected data can be sent to Traceloop's own platform or to existing observability backends like Datadog and Honeycomb.
