The honest brief
DeepEval
Write LLM evals as Pytest-style assertions and run them in CI, backed by 50+ metrics across RAG, agents, and safety.
- Assertions run in your CI pipeline
- Metrics for RAG, agents, and safety
- Bring any judge model (BYO key)
- Integrates LangChain/CrewAI/OpenAI
- LLM-as-judge adds cost
- Dashboards need paid Confident AI
- Judge metrics can be noisy
TruLens
Pioneered the RAG Triad — context relevance, groundedness, answer relevance — as feedback functions you attach to score and trace any LLM app.
- OpenTelemetry tracing, runs locally
- RAG Triad feedback functions built in
- Provider-agnostic LLM-as-judge metrics
- Leaderboard to compare app versions
- Python library, no hosted SaaS
- Smaller community than LangSmith/Langfuse
- Setup to wire feedback providers
