OpenLLMetry is an open-source observability library for GenAI and LLM applications, built on OpenTelemetry. It is written in Python and published under the Apache-2.0 license by the traceloop organization.

Use it when you want standards-based OpenTelemetry tracing and monitoring for your LLM application instead of a proprietary vendor SDK.

Use it to

  • Instrument LLM applications with OpenTelemetry
  • Collect metrics and traces from GenAI pipelines
  • Monitor model usage and behavior in production
  • Export telemetry to existing observability backends

For Developers running LLM applications who need observability
