              • Root cause analysis
              • Real-time alerts

              Common complaints

              Buyer sentiment is very strong across 185 reviews, with consistently positive feedback.

              What buyers like

              • MIT open-source license with Docker-based self-hosting means teams with data privacy requirements can run full LLM observability without sending traces to a third-party cloud.
              • Generous free cloud tier (50k traces/month) covers most early-stage AI applications without any cost.
              • Session-level trace grouping links multiple LLM calls into user sessions — enabling product-level analysis of where users encounter AI failures.

              Common complaints

              • Smaller ecosystem and fewer integrations than LangSmith — some niche frameworks require manual instrumentation rather than automatic SDK integration.
              • Self-hosting requires Docker knowledge and ongoing maintenance; small teams without DevOps support may prefer the managed cloud.

              Pros and Cons

              • Provides tried-and-tested workarounds that can be applied directly to production code without deep technical knowledge

              • User-friendly and simple interface enabling quick onboarding and use

              • Real-time alerts and root cause analysis for efficient problem resolution

              • Alert notifications can become overwhelming without proper filtering during high-traffic periods

              • Limited customization options for advanced or tailored configurations

              • MIT open-source license with Docker-based self-hosting means teams with data privacy requirements can run full LLM observability without sending traces to a third-party cloud.
