Open-source OpenTelemetry-native observability platform for GenAI, LLM and AI application stacks.

-

Our Verdict

Right approach with OTel-native GenAI observability; solid pick if you value open standards over polish.

Pros

  • OTel-native tracing for LLM and GenAI apps
  • Open-source with Apache 2.0 license
  • Drop-in with OpenAI, Anthropic, and vector DBs
  • Avoids lock-in to proprietary LLMOps platforms

Cons

  • Young project with evolving APIs
  • Self-hosting burden vs managed Langfuse
  • UI less polished than Braintrust or LangSmith
  • Smaller community than established LLMOps tools
Best for: Teams wanting vendor-neutral LLM observability tied to existing OTel pipelines. Not for: Teams preferring polished managed LLMOps with evals and PM-friendly UX.

When to Use OpenLIT

Good fit if you need

  • OpenTelemetry observability for LLM and GenAI stacks
  • Trace token usage, latency, and cost per LLM call
  • Monitor prompt evaluation quality in AI pipelines
  • Open-source alternative to Langfuse and Helicone
