Best for
Python developers building production LLM systems who need observability and systematic evaluation.
Use cases
- Debug LLM application behavior by inspecting full execution traces
- Evaluate RAG retrieval and generation quality with automated test suites
- Monitor agentic workflows in production for performance and failure patterns

19,417 stars on GitHub. Last updated 2026-06-01. Licensed Apache-2.0.
Pros
- Comprehensive tracing captures full context across LLM calls and tool interactions
- Automated evaluation framework reduces manual testing overhead
- Open-source with active community support
Cons
- Python-only, not suitable for non-Python LLM stacks
- Requires integration work to instrument existing applications
- Dashboard and evaluation features depend on proper trace instrumentation
