A like-for-like, spec-level comparison. Both entries are verified against their docs and repo.

OpenLLMetry

OpenTelemetry instrumentation for LLMs.

  • + Vendor-neutral instrumentation
  • + Works with existing observability stacks
  • − Instrumentation only, no UI
  • − Needs a backend like SigNoz or Honeycomb

SigNoz

Open-source OpenTelemetry observability.

  • + Unified app and LLM tracing on OTel
  • + Fully self-hosted, no vendor lock-in
  • − LLM evals via OpenLLMetry, not native
  • − More ops to run than a SaaS
