              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.
